Load Balance can help to distribute the traffic for all of the access points (e.g., VigorAP
920RP) registered to Vigor router. Thus, the bandwidth will not be occupied by certain
access points.
However, traffic overload might be occurred if too many wireless stations connected to
VigorAP 920RP for data incoming and outgoing. Therefore, “Force Overload
Disassociation” is required to terminate the network connection of the client’s station to
release network traffic. When the function of “Force Overload Disassociation” in web user
interface of Vigor router (e.g., Vigor2860 or Vigor2925 series) is enabled, wireless clients
specified in black list of such web page will be disassociated to solve the problem of traffic
overload.

WEP (Wired Equivalent Privacy) is a legacy method to encrypt each frame transmitted via
radio using either a 64-bit or 128-bit key. Usually access point will preset a set of four keys
and it will communicate with each station using only one out of the four keys.
WPA (Wi-Fi Protected Access), the most dominating security mechanism in industry, is
separated into two categories: WPA-personal or called WPA Pre-Share Key (WPA/PSK),
and WPA-Enterprise or called WPA/802.1x.
In WPA-Personal, a pre-defined key is used for encryption during data transmission. WPA
applies Temporal Key Integrity Protocol (TKIP) for data encryption while WPA2 applies
AES. The WPA-Enterprise combines not only encryption but also authentication.
Since WEP has been proved vulnerable, you may consider using WPA for the most secure
connection. You should select the appropriate security mechanism according to your needs.
No matter which security suite you select, they all will enhance the over-the-air data
protection and /or privacy on your wireless network. The VigorAP 920RP is very flexible
and can support multiple secure connections with both WEP and WPA at the same time.

It is the simplest way to build connection between wireless network clients and VigorAP
920RP. Users do not need to select any encryption mode and type any long encryption
passphrase to setup a wireless client every time. He/she only needs to press a button on
wireless client, and WPS will connect for client and VigorAP 920RP automatically.
Note: Such function is available for the wireless station with WPS supported.
There are two methods to do network connection through WPS between AP and Stations:
pressing the Start PBC button or using PIN Code.
On the side of VigorAP 920RP series which served as an AP, press WPS button once on the
front panel of VigorAP 920RP or click Start PBC on web configuration interface. On the
side of a station with network card installed, press Start PBC button of network card.
If you want to use PIN code, you have to know the PIN code specified in wireless client.
Then provide the PIN code of the wireless client you wish to connect to the VigorAP 920RP.

Depending on the wireless utility, the user may only see the
information except SSID or just cannot see any thing about
VigorAP 920RP while site surveying. The system allows you
to set four sets of SSID for different usage.
SSID
Set a name for VigorAP 920RP to be identified. Default setting
is DrayTek.
Isolate Member
Check this box to make the wireless clients (stations) with the
same SSID not access for each other.
VLAN ID
Type the value for such SSID. Packets transferred from such
SSID to LAN will be tagged with the number.
If your network uses VLANs, you can assign the SSID to a
VLAN on your network. Client devices that associate using the
SSID are grouped into this VLAN. The VLAN ID range is
from 3 to 4095. The VLAN ID is 0 by default, it means
disabling the VLAN function for the SSID.

This page is to determine which algorithm will be selected for wireless transmission rate.
Available settings are explained as follows:
Item Description
Channel Width
20 MHz- the device will use 20MHz for data transmission and
receiving between the AP and the stations.
Auto 20/40 MHz – VigorAP will scan for nearby wireless AP
to determine which channel width (20MHz or 40MHz) shall be
used to meet the air situation. Usually, 40MHz would have
better performance under the clean wireless environment (e.g.,
less wireless traffic / contention). When the air condition is not
satisfied (e.g., dirty air), 20MHz will be used by VigorAP
automatically to ensure smooth network transmission.
40 MHz- the device will use 40MHz for data transmission and
receiving between the AP and the stations.
Antenna
VigorAP can be attached with two antennas to have good data
transmission via wireless connection. However, if you have
only one antenna attached, please choose 1T1R.

WMM is an abbreviation of Wi-Fi Multimedia. It defines the priority levels for four access
categories derived from 802.1d (prioritization tabs). The categories are designed with
specific types of traffic, voice, video, best effort and low priority data. There are four
accessing categories - AC_BE , AC_BK, AC_VI and AC_VO for WMM.
Available settings are explained as follows:
Item Description
WMM Capable
To apply WMM parameters for wireless data transmission,
please click the Enable radio button.
APSD Capable
APSD (automatic power-save delivery) is an enhancement over
the power-save mechanisms supported by Wi-Fi networks. It
allows devices to take more time in sleeping state and consume
less power to improve the performance by minimizing
transmission latency.
The default setting is Disable.
Aifsn
It controls how long the client waits for each data transmission.
Please specify the value ranging from 1 to 15. Such parameter
will influence the time delay for WMM accessing categories.
For the service of voice or video image, please set small value
for AC_VI and AC_VO categories For the service of e-mail or
web browsing, please set large value for AC_BE and AC_BK
categories.
CWMin/CWMax
CWMin means contention Window-Min and CWMax means
contention Window-Max. Please specify the value ranging from
1 to 15. Be aware that CWMax value must be greater than
CWMin or equals to CWMin value. Both values will influence
VigorAP 920R Series User’s Guide
56
the time delay for WMM accessing categories. The difference
between AC_VI and AC_VO categories must be smaller;
however, the difference between AC_BE and AC_BK categories
must be greater.
Txop
It means transmission opportunity. For WMM categories of
AC_VI and AC_VO that need higher priorities in data
transmission, please set greater value for them to get highest
transmission opportunity. Specify the value ranging from 0 to
65535.
AckPolicy
“Uncheck” (default value) the box means the AP will answer the
response request while transmitting WMM packets through
wireless connection. It can assure that the peer must receive the
WMM packets.
“Check” the box means the AP will not answer any response
request for the transmitting packets. It will have better
performance with lower reliability.
ACM
It is an abbreviation of Admission control Mandatory. It can
restrict stations from using specific category class if it is

Airtime fairness is essential in wireless networks that must support critical enterprise
applications.
Most of the applications are either symmetric or require more downlink than uplink capacity;
telephony and email send the same amount of data in each direction, while video streaming
and web surfing involve more traffic sent from access points to clients than the other way
around. This is essential for ensuring predictable performance and quality-of-service, as well
as allowing 802.11n and legacy clients to coexist on the same network. Without airtime
fairness, offices using mixed mode networks risk having legacy clients slow down the entire
network or letting the fastest client(s) crowd out other users.
With airtime fairness, every client at a given quality-of-service level has equal access to the
network's airtime.
The wireless channel can be accessed by only one wireless station at the same time.
The principle behind the IEEE802.11 channel access mechanisms is that each station has
equal probability to access the channel. When wireless stations have similar data rate, this
principle leads to a fair result. In this case, stations get similar channel access time which is
called airtime.
However, when stations have various data rate (e.g., 11g, 11n), the result is not fair. The
slow stations (11g) work in their slow data rate and occupy too much airtime, whereas the
fast stations (11n) become much slower.
Take the following figure as an example, both Station A(11g) and Station B(11n) transmit
data packets through VigorAP 920RP. Although they have equal probability to access the
wireless channel, Station B(11n) gets only a little airtime and waits too much because Station
A(11g) spends longer time to send one packet. In other words, Station B(fast rate) is
obstructed by Station A(slow rate).
To improve this problem, Airtime Fairness is added for VigorAP 920RP. Airtime Fairness
function tries to assign similar airtime to each station (A/B) by controlling TX traffic. In the
following figure, Station B(11n) has higher probability to send data packets than Station
A(11g). By this way, Station B(fast rate) gets fair airtime and it's speed is not limited by
Station A(slow rate).
VigorAP 920R Series User’s Guide
59
It is similar to automatic Bandwidth Limit. The dynamic bandwidth limit of each station
depends on instant active station number and airtime assignment. Please note that Airtime
Fairness of 2.4GHz and 5GHz are independent. But stations of different SSIDs function
together, because they all use the same wireless channel. IN SPECIFIC ENVIRONMENTS,
this function can reduce the bad influence of slow wireless devices and improve the overall
wireless performance.
Suitable environment:
(1) Many wireless stations.
(2) All stations mainly use download traffic.
(3) The performance bottleneck is wireless connection.
Available settings are explained as follows:
Item Description

Such feature is especially useful for free Wi-Fi service. For example, a coffee shop offers
free Wi-Fi service for its guests for one hour every day. Then, the connection time can be set
as “1 hour” and reconnection time can be set as “1 day”. Thus, the guest can finish his job
within one hour and will not occupy the wireless network for a long time.

The network signal for a single wireless access point might be limited by its coverage range.
Therefore, if you want to expand the wireless network in a large exhibition with a quick
method, you can install multiple access points with enabling the Roaming feature for each
AP to reach the purpose of expanding wireless signals seamlessly.
These access points connecting for each other shall be verified by pre-authentication. This
page allows you to enable the roaming feature and the pre-authentication.
Available settings are explained as follows:
Item Description
AP-assisted Client
Roaming Parameters
When the link rate of wireless station is too low or the signal
received by the wireless station is too worse, VigorAP 920RP
will automatically detect (based on the link rate and RSSI
requirement) and cut off the network connection for that wireless
station to assist it to connect another Wireless AP to get better
signal.
Minimum Basic Rate – Check the box to use the drop down list
to specify a basic rate (Mbps). When the link rate of the wireless
station is below such value, VigorAP 920RP will terminate the
network connection for that wireless station.
Disable RSSI Requirement - If it is selected, VigorAP will not
terminate the network connection based on RSSI.
Strictly Minimum RSSI - VigorAP uses RSSI (received signal
strength indicator) to decide to terminate the network connection
of wireless station. When the signal strength is below the value
(dBm) set here, VigorAP 920RP will terminate the network
connection for that wireless station.
VigorAP 920R Series User’s Guide
62
Minimum RSSI - When the signal strength of the wireless
station is below the value (dBm) set here and adjacent AP (must
be DrayTek AP and support such feature too) with higher signal
strength value (defined in the field of With Adjacent AP RSSI
over) is detected by VigorAP 920RP, VigorAP 920RP will
terminate the network connection for that wireless station. Later,
the wireless station can connect to the adjacent AP (with better
RSSI).
With Adjacent AP RSSI over – Specify a value as a
threshold.
Fast Roaming
(WPA2/802.1x)
Enable – Check the box to enable fast roaming configuration.
PMK Caching - Set the expire time of WPA2 PMK (Pairwise
master key) cache. PMK Cache manages the list from the
BSSIDs in the associated SSID with which it has
pre-authenticated. Such feature is available for WPA2/802.1
mode.
Pre-Authentication - Enables a station to authenticate to
multiple APs for roaming securer and faster. With the
pre-authentication procedure defined in IEEE 802.11i
specification, the pre-four-way-handshake can reduce handoff
delay perceivable by a mobile node. It makes roaming faster and
more secure. (Only valid in WPA2)

Band Steering detects if the wireless clients are capable of 5GHz operation, and steers them
to that frequency. It helps to leave 2.4GHz band available for legacy clients, and improves
users experience by reducing channel utilization.
If dual-band is detected, the AP will let the wireless client connect to less congested wireless
LAN, such as 5GHz to prevent from network congestion.
Note: To make Band Steering work successfully, SSID and security on 2.4GHz also
MUST be broadcasted on 5GHz.

WMM is an abbreviation of Wi-Fi Multimedia. It defines the priority levels for four access
categories derived from 802.1d (prioritization tabs). The categories are designed with
specific types of traffic, voice, video, best effort and low priority data. There are four
accessing categories - AC_BE , AC_BK, AC_VI and AC_VO for WMM.
Available settings are explained as follows:
Item Description
WMM Capable
To apply WMM parameters for wireless data transmission,
please click the Enable radio button.
APSD Capable
APSD (automatic power-save delivery) is an enhancement over
the power-save mechanisms supported by Wi-Fi networks. It
allows devices to take more time in sleeping state and consume
less power to improve the performance by minimizing
transmission latency.
Aifsn
It controls how long the client waits for each data transmission.
Please specify the value ranging from 1 to 15. Such parameter
will influence the time delay for WMM accessing categories.
For the service of voice or video image, please set small value
for AC_VI and AC_VO categories For the service of e-mail or
web browsing, please set large value for AC_BE and AC_BK
categories.
CWMin/CWMax
CWMin means contention Window-Min and CWMax means
contention Window-Max. Please specify the value ranging from
1 to 15. Be aware that CWMax value must be greater than
CWMin or equals to CWMin value. Both values will influence
the time delay for WMM accessing categories. The difference
VigorAP 920R Series User’s Guide
90
between AC_VI and AC_VO categories must be smaller;
however, the difference between AC_BE and AC_BK categories
must be greater.
Txop
It means transmission opportunity. For WMM categories of
AC_VI and AC_VO that need higher priorities in data
transmission, please set greater value for them to get highest
transmission opportunity. Specify the value ranging from 0 to
65535.
AckPolicy
“Uncheck” (default value) the box means the AP will answer the
response request while transmitting WMM packets through
wireless connection. It can assure that the peer must receive the
WMM packets.
“Check” the box means the AP will not answer any response
request for the transmitting packets. It will have better
performance with lower reliability.
ACM
It is an abbreviation of Admission control Mandatory. It can
restrict stations from using specific category class if it is
checked.
Note: VigorAP 920RP provides standard WMM configuration
in the web page. If you want to modify the parameters, please
refer to the Wi-Fi WMM standard specification.

Airtime fairness is essential in wireless networks that must support critical enterprise
applications.
Most of the applications are either symmetric or require more downlink than uplink capacity;
telephony and email send the same amount of data in each direction, while video streaming
and web surfing involve more traffic sent from access points to clients than the other way
around. This is essential for ensuring predictable performance and quality-of-service, as well
as allowing 802.11n and legacy clients to coexist on the same network. Without airtime
fairness, offices using mixed mode networks risk having legacy clients slow down the entire
network or letting the fastest client(s) crowd out other users.
With airtime fairness, every client at a given quality-of-service level has equal access to the
network's airtime.
The wireless channel can be accessed by only one wireless station at the same time.
The principle behind the IEEE802.11 channel access mechanisms is that each station has
equal probability to access the channel. When wireless stations have similar data rate, this
principle leads to a fair result. In this case, stations get similar channel access time which is
called airtime.
However, when stations have various data rate (e.g., 11g, 11n), the result is not fair. The
slow stations (11g) work in their slow data rate and occupy too much airtime, whereas the
fast stations (11n) become much slower.
Take the following figure as an example, both Station A(11g) and Station B(11n) transmit
data packets through VigorAP 920RP. Although they have equal probability to access the
wireless channel, Station B(11n) gets only a little airtime and waits too much because Station
A(11g) spends longer time to send one packet. In other words, Station B(fast rate) is
obstructed by Station A(slow rate).
To improve this problem, Airtime Fairness is added for VigorAP 920RP. Airtime Fairness
function tries to assign similar airtime to each station (A/B) by controlling TX traffic. In the
following figure, Station B(11n) has higher probability to send data packets than Station
A(11g). By this way, Station B(fast rate) gets fair airtime and it's speed is not limited by
Station A(slow rate).
VigorAP 920R Series User’s Guide
93
It is similar to automatic Bandwidth Limit. The dynamic bandwidth limit of each station
depends on instant active station number and airtime assignment. Please note that Airtime
Fairness of 2.4GHz and 5GHz are independent. But stations of different SSIDs function
together, because they all use the same wireless channel. IN SPECIFIC ENVIRONMENTS,
this function can reduce the bad influence of slow wireless devices and improve the overall
wireless performance.
Suitable environment:
(1) Many wireless stations.
(2) All stations mainly use download traffic.
(3) The performance bottleneck is wireless connection.
Available settings are explained as follows:
Item Description

Station Control is used to specify the duration for the wireless client to connect and
reconnect VigorAP. If such function is not enabled, the wireless client can connect VigorAP
until it shuts down.
Such feature is especially useful for free Wi-Fi service. For example, a coffee shop offers
free Wi-Fi service for its guests for one hour every day. Then, the connection time can be set
as “1 hour” and reconnection time can be set as “1 day”. Thus, the guest can finish his job
within one hour and will not occupy the wireless network for a long time.
Note: Up to 300 Wireless Station records are supported by VigorAP.

The network signal for a single wireless access point might be limited by its coverage range.
Therefore, if you want to expand the wireless network in a large exhibition with a quick
method, you can install multiple access points with enabling the Roaming feature for each
AP to reach the purpose of expanding wireless signals seamlessly.
These access points connecting for each other shall be verified by pre-authentication. This
page allows you to enable the roaming feature and the pre-authentication.
Available settings are explained as follows:
Item Description
AP-assisted Client
Roaming Parameters
When the link rate of wireless station is too low or the signal
received by the wireless station is too worse, VigorAP 920RP
will automatically detect (based on the link rate and RSSI
requirement) and cut off the network connection for that wireless
station to assist it to connect another Wireless AP to get better
signal.
Minimum Basic Rate – Check the box to use the drop down list
to specify a basic rate (Mbps). When the link rate of the wireless
station is below such value, VigorAP 920RP will terminate the
network connection for that wireless station.
Disable RSSI Requirement - If it is selected, VigorAP will not
terminate the network connection based on RSSI.
Strictly Minimum RSSI - VigorAP uses RSSI (received signal
strength indicator) to decide to terminate the network connection
of wireless station. When the signal strength is below the value
(dBm) set here, VigorAP 920RP will terminate the network
connection for that wireless station.
Minimum RSSI - When the signal strength of the wireless
station is below the value (dBm) set here and adjacent AP (must
VigorAP 920R Series User’s Guide
96
be DrayTek AP and support such feature too) with higher signal
strength value (defined in the field of With Adjacent AP RSSI
over) is detected by VigorAP 920RP, VigorAP 920RP will
terminate the network connection for that wireless station. Later,
the wireless station can connect to the adjacent AP (with better
RSSI).
With Adjacent AP RSSI over – Specify a value as a
threshold.
Fast Roaming
(WPA2/802.1x)
Enable – Check the box to enable fast roaming configuration.
PMK Caching - Set the expire time of WPA2 PMK (Pairwise
master key) cache. PMK Cache manages the list from the
BSSIDs in the associated SSID with which it has
pre-authenticated. Such feature is available for WPA2/802.1x
mode.
Pre-Authentication - Enables a station to authenticate to
multiple APs for roaming securer and faster. With the
pre-authentication procedure defined in IEEE 802.11i
specification, the pre-four-way-handshake can reduce handoff
delay perceivable by a mobile node. It makes roaming faster and
more secure. (Only valid in WPA2)

Band Steering detects if the wireless clients are capable of 5GHz operation, and steers them
to that frequency. It helps to leave 2.4GHz band available for legacy clients, and improves
users experience by reducing channel utilization.
If dual-band is detected, the AP will let the wireless client connect to less congested wireless
LAN, such as 5GHz to prevent from network congestion.
Note: To make Band Steering work successfully, SSID and security on 2.4GHz also
MUST be broadcasted on 5GHz.
VigorAP 920R Series User’s Guide
98
Open Wireless LAN (2.4GHz)>>Band Steering to get the following web page:
Available settings are explained as follows:
Item Description
Enable Band Steering
If it is enabled, VigorAP will detect if the wireless client is
capable of dual-band or not within the time limit.
Check Time…. – If the wireless station does not have the
capability of 5GHz network connection, the system shall
wait and check for several seconds (15 seconds, in default)
to make the 2.4GHz network connection. Specify the time
limit for VigorAP to detect the wireless client.
5GHz Minimum RSSI – The wireless station has the
capability of 5GHz network connection, yet the signal
performance might not be satisfied. Therefore, when the
signal strength is below the value set here while the
wireless station connecting to VigorAP 920RP, VigorAP
will allow the client to connect to 2.4GHz network.
Overloaded – If it is enabled, VigorAP will activate the
band steering according to the conditions set below.
2.4GHz Utilization Overload Threshold – The
default setting is 70%. It can define the network
congestion for 2.4GHz.
5GHz Utilization Overload Threshold – The default
setting is 70%. It can define the network congestion
for 5GHz.
When the utilization of 2.4GHz is higher than the specified
threshold and the utilization of 5GHz is lower than the
specified threshold, VigorAP will steer the client to connect
to 5GHz network.

This page is to determine which algorithm will be selected for wireless transmission rate.
Available settings are explained as follows:
Item Description
Channel Width
20 MHz - the AP will use 20MHz for data transmission and
receiving between the AP and the stations.
Auto 20/40 MHz – VigorAP will scan for nearby wireless AP
to determine which channel width (20MHz or 40MHz) shall be
used to meet the air situation. Usually, 40MHz would have
better performance under the clean wireless environment (e.g.,
less wireless traffic / contention). When the air condition is not
satisfied (e.g., dirty air), 20MHz will be used by VigorAP
automatically to ensure smooth network transmission.
40 MHz - the AP will use 40MHz for data transmission and
receiving between the AP and the stations.
Antenna
VigorAP can be attached with two antennas to have good data
transmission via wireless connection. However, if you have
only one antenna attached, please choose 1T1R.
Fragment Length
Set the Fragment threshold of wireless radio. Do not modify
default value if you don’t know what it is, default value is
2346.
RTS Threshold
Minimize the collision (unit is bytes) between hidden stations
to improve wireless performance.
Set the RTS threshold of wireless radio. Do not modify default
value if you don’t know what it is, default value is 2347.
Country Code
VigorAP broadcasts country codes by following the 802.11d
standard. However, some wireless stations will detect / scan
the country code to prevent conflict occurred. If conflict is
detected, wireless station will be warned and is unable to make
VigorAP 920R Series User’s Guide

for AC_VI and AC_VO categories For the service of e-mail or
web browsing, please set large value for AC_BE and AC_BK
categories.
CWMin/CWMax
CWMin means contention Window-Min and CWMax means
contention Window-Max. Please specify the value ranging from
1 to 15. Be aware that CWMax value must be greater than
CWMin or equals to CWMin value. Both values will influence
the time delay for WMM accessing categories. The difference
between AC_VI and AC_VO categories must be smaller;
however, the difference between AC_BE and AC_BK categories
must be greater.
Txop
It means transmission opportunity. For WMM categories of

Airtime fairness is essential in wireless networks that must support critical enterprise
applications.
Most of the applications are either symmetric or require more downlink than uplink capacity;
telephony and email send the same amount of data in each direction, while video streaming
and web surfing involve more traffic sent from access points to clients than the other way
around. This is essential for ensuring predictable performance and quality-of-service, as well
as allowing 802.11n and legacy clients to coexist on the same network. Without airtime
fairness, offices using mixed mode networks risk having legacy clients slow down the entire
network or letting the fastest client(s) crowd out other users.
With airtime fairness, every client at a given quality-of-service level has equal access to the
network's airtime.
The wireless channel can be accessed by only one wireless station at the same time.
The principle behind the IEEE802.11 channel access mechanisms is that each station has
equal probability to access the channel. When wireless stations have similar data rate, this
principle leads to a fair result. In this case, stations get similar channel access time which is
called airtime.
However, when stations have various data rate (e.g., 11g, 11n), the result is not fair. The
slow stations (11g) work in their slow data rate and occupy too much airtime, whereas the
fast stations (11n) become much slower.
Take the following figure as an example, both Station A(11g) and Station B(11n) transmit
data packets through VigorAP 920RP. Although they have equal probability to access the
wireless channel, Station B(11n) gets only a little airtime and waits too much because Station
A(11g) spends longer time to send one packet. In other words, Station B(fast rate) is
obstructed by Station A(slow rate).
To improve this problem, Airtime Fairness is added for VigorAP 920RP. Airtime Fairness
function tries to assign similar airtime to each station (A/B) by controlling TX traffic. In the
following figure, Station B(11n) has higher probability to send data packets than Station
A(11g). By this way, Station B(fast rate) gets fair airtime and it's speed is not limited by
Station A(slow rate).
VigorAP 920R Series User’s Guide
121
It is similar to automatic Bandwidth Limit. The dynamic bandwidth limit of each station
depends on instant active station number and airtime assignment. Please note that Airtime
Fairness of 2.4GHz and 5GHz are independent. But stations of different SSIDs function
together, because they all use the same wireless channel. IN SPECIFIC ENVIRONMENTS,
this function can reduce the bad influence of slow wireless devices and improve the overall
wireless performance.
Suitable environment:
(1) Many wireless stations.
(2) All stations mainly use download traffic.
(3) The performance bottleneck is wireless connection.
Available settings are explained as follows:

Station Control is used to specify the duration for the wireless client to connect and
reconnect VigorAP. If such function is not enabled, the wireless client can connect VigorAP
until it shuts down.
Such feature is especially useful for free Wi-Fi service. For example, a coffee shop offers
free Wi-Fi service for its guests for one hour every day. Then, the connection time can be set
as “1 hour” and reconnection time can be set as “1 day”. Thus, the guest can finish his job
within one hour and will not occupy the wireless network for a long time.
Note: Up to 300 Wireless Station records are supported by VigorAP.

The network signal for a single wireless access point might be limited by its coverage range.
Therefore, if you want to expand the wireless network in a large exhibition with a quick
method, you can install multiple access points with enabling the Roaming feature for each
AP to reach the purpose of expanding wireless signals seamlessly.
These access points connecting for each other shall be verified by pre-authentication. This
page allows you to enable the roaming feature and the pre-authentication.
Available settings are explained as follows:
Item Description
AP-assisted Client
Roaming Parameters
When the link rate of wireless station is too low or the signal
received by the wireless station is too worse, VigorAP 920RP
will automatically detect (based on the link rate and RSSI
requirement) and cut off the network connection for that wireless
station to assist it to connect another Wireless AP to get better
signal.
Minimum Basic Rate – Check the box to use the drop down list
to specify a basic rate (Mbps). When the link rate of the wireless
station is below such value, VigorAP 920RP will terminate the
network connection for that wireless station.
Disable RSSI Requirement - If it is selected, VigorAP will not
terminate the network connection based on RSSI.
Strictly Minimum RSSI - VigorAP uses RSSI (received signal
strength indicator) to decide to terminate the network connection
of wireless station. When the signal strength is below the value
(dBm) set here, VigorAP 920RP will terminate the network
connection for that wireless station.
Minimum RSSI - When the signal strength of the wireless
station is below the value (dBm) set here and adjacent AP (must
be DrayTek AP and support such feature too) with higher signal
strength value (defined in the field of With Adjacent AP RSSI
over) is detected by VigorAP 920RP, VigorAP 920RP will
terminate the network connection for that wireless station. Later,
VigorAP 920R Series User’s Guide
124
the wireless station can connect to the adjacent AP (with better
RSSI).
With Adjacent AP RSSI over – Specify a value as a
threshold.
Fast Roaming
(WPA2/802.1x)
Enable – Check the box to enable fast roaming configuration.
PMK Caching - Set the expire time of WPA2 PMK (Pairwise
master key) cache. PMK Cache manages the list from the
BSSIDs in the associated SSID with which it has
pre-authenticated. Such feature is available for WPA2/802.1
mode.
Pre-Authentication - Enables a station to authenticate to
multiple APs for roaming securer and faster. With the
pre-authentication procedure defined in IEEE 802.11i
specification, the pre-four-way-handshake can reduce handoff
delay perceivable by a mobile node. It makes roaming faster and
more secure. (Only valid in WPA2)

Band Steering detects if the wireless clients are capable of 5GHz operation, and steers them
to that frequency. It helps to leave 2.4GHz band available for legacy clients, and improves
users experience by reducing channel utilization.
If dual-band is detected, the AP will let the wireless client connect to less congested wireless
LAN, such as 5GHz to prevent from network congestion.
Note: To make Band Steering work successfully, SSID and security on 2.4GHz also
MUST be broadcasted on 5GHz.
VigorAP 920R Series User’s Guide

Open Wireless LAN (2.4GHz)>>Band Steering to get the following web page:
Available settings are explained as follows:
Item Description
Enable Band Steering
If it is enabled, VigorAP will detect if the wireless client is
capable of dual-band or not within the time limit.
Check Time…. – If the wireless station does not have the
capability of 5GHz network connection, the system shall
wait and check for several seconds (15 seconds, in default)
to make the 2.4GHz network connection. Specify the time
limit for VigorAP to detect the wireless client.
5GHz Minimum RSSI – The wireless station has the
capability of 5GHz network connection, yet the signal
performance might not be satisfied. Therefore, when the
signal strength is below the value set here while the
wireless station connecting to VigorAP 920RP, VigorAP
will allow the client to connect to 2.4GHz network.
Overloaded – If it is enabled, VigorAP will activate the
band steering according to the conditions set below.
2.4GHz Utilization Overload Threshold – The
default setting is 70%. It can define the network
congestion for 2.4GHz.
5GHz Utilization Overload Threshold – The default
setting is 70%. It can define the network congestion
for 5GHz.
When the utilization of 2.4GHz is higher than the specified
threshold and the utilization of 5GHz is lower than the
specified threshold, VigorAP will steer the client to connect
to 5GHz network.
After finishing this web page configuration, please click OK to save the settings.

This page is to determine which algorithm will be selected for wireless transmission rate.
Available settings are explained as follows:
Item Description
Channel Width
20 MHz- the AP will use 20MHz for data transmission and
receiving between the AP and the stations.
Auto 20/40 MHz – VigorAP will scan for nearby wireless AP
to determine which channel width (20MHz or 40MHz) shall be
used to meet the air situation. Usually, 40MHz would have
better performance under the clean wireless environment (e.g.,
less wireless traffic / contention). When the air condition is not
satisfied (e.g., dirty air), 20MHz will be used by VigorAP
automatically to ensure smooth network transmission.
Fragment Length
Set the Fragment threshold of wireless radio. Do not modify
default value if you don’t know what it is, default value is
2346.
RTS Threshold
Minimize the collision (unit is bytes) between hidden stations
to improve wireless performance.
Set the RTS threshold of wireless radio. Do not modify default
value if you don’t know what it is, default value is 2347.
Country Code
VigorAP broadcasts country codes by following the 802.11d
standard. However, some wireless stations will detect / scan
the country code to prevent conflict occurred. If conflict is
detected, wireless station will be warned and is unable to make
network connection. Therefore, changing the country code to
ensure successful network connection will be necessary for
some clients.
Auto Channel

WMM is an abbreviation of Wi-Fi Multimedia. It defines the priority levels for four access
categories derived from 802.1d (prioritization tabs). The categories are designed with
specific types of traffic, voice, video, best effort and low priority data. There are four
accessing categories - AC_BE , AC_BK, AC_VI and AC_VO for WMM.
Available settings are explained as follows:
Item Description
WMM Capable
To apply WMM parameters for wireless data transmission,
please click the Enable radio button.
APSD Capable
APSD (automatic power-save delivery) is an enhancement over
the power-save mechanisms supported by Wi-Fi networks. It
allows devices to take more time in sleeping state and consume
less power to improve the performance by minimizing
transmission latency.
The default setting is Disable.
Aifsn
It controls how long the client waits for each data transmission.
Please specify the value ranging from 1 to 15. Such parameter
will influence the time delay for WMM accessing categories.
For the service of voice or video image, please set small value
for AC_VI and AC_VO categories For the service of e-mail or
web browsing, please set large value for AC_BE and AC_BK
categories.
CWMin/CWMax
CWMin means contention Window-Min and CWMax means
contention Window-Max. Please specify the value ranging from
1 to 15. Be aware that CWMax value must be greater than
CWMin or equals to CWMin value. Both values will influence
the time delay for WMM accessing categories. The difference
between AC_VI and AC_VO categories must be smaller;
however, the difference between AC_BE and AC_BK categories
must be greater.
VigorAP 920R Series User’s Guide
143
Txop
It means transmission opportunity. For WMM categories of
AC_VI and AC_VO that need higher priorities in data
transmission, please set greater value for them to get highest
transmission opportunity. Specify the value ranging from 0 to
65535.
AckPolicy
“Uncheck” (default value) the box means the AP will answer the
response request while transmitting WMM packets through
wireless connection. It can assure that the peer must receive the
WMM packets.
“Check” the box means the AP will not answer any response
request for the transmitting packets. It will have better
performance with lower reliability.
ACM
It is an abbreviation of Admission control Mandatory. It can
restrict stations from using specific category class if it is
checked.

Airtime fairness is essential in wireless networks that must support critical enterprise
applications.
Most of the applications are either symmetric or require more downlink than uplink capacity;
telephony and email send the same amount of data in each direction, while video streaming
and web surfing involve more traffic sent from access points to clients than the other way
around. This is essential for ensuring predictable performance and quality-of-service, as well
as allowing 802.11n and legacy clients to coexist on the same network. Without airtime
fairness, offices using mixed mode networks risk having legacy clients slow down the entire
network or letting the fastest client(s) crowd out other users.
With airtime fairness, every client at a given quality-of-service level has equal access to the
network's airtime.
After finishing this web page configuration, please click OK to save the settings.
The wireless channel can be accessed by only one wireless station at the same time.
The principle behind the IEEE802.11 channel access mechanisms is that each station has
equal probability to access the channel. When wireless stations have similar data rate, this
principle leads to a fair result. In this case, stations get similar channel access time which is
called airtime.
However, when stations have various data rate (e.g., 11g, 11n), the result is not fair. The
slow stations (11g) work in their slow data rate and occupy too much airtime, whereas the
fast stations (11n) become much slower.
Take the following figure as an example, both Station A(11g) and Station B(11n) transmit
data packets through VigorAP 920RP. Although they have equal probability to access the
wireless channel, Station B(11n) gets only a little airtime and waits too much because Station
A(11g) spends longer time to send one packet. In other words, Station B(fast rate) is
obstructed by Station A(slow rate).
VigorAP 920R Series User’s Guide
145
To improve this problem, Airtime Fairness is added for VigorAP 920RP. Airtime Fairness
function tries to assign similar airtime to each station (A/B) by controlling TX traffic. In the
following figure, Station B(11n) has higher probability to send data packets than Station
A(11g). By this way, Station B(fast rate) gets fair airtime and it's speed is not limited by
Station A(slow rate).
It is similar to automatic Bandwidth Limit. The dynamic bandwidth limit of each station
depends on instant active station number and airtime assignment. Please note that Airtime
Fairness of 2.4GHz and 5GHz are independent. But stations of different SSIDs function
together, because they all use the same wireless channel. IN SPECIFIC ENVIRONMENTS,
this function can reduce the bad influence of slow wireless devices and improve the overall
wireless performance.
Suitable environment:
(1) Many wireless stations.
(2) All stations mainly use download traffic.
(3) The performance bottleneck is wireless connection.
Available settings are explained as follows:

Station Control is used to specify the duration for the wireless client to connect and
reconnect VigorAP. If such function is not enabled, the wireless client can connect VigorAP
until it shuts down.
Such feature is especially useful for free Wi-Fi service. For example, a coffee shop offers
free Wi-Fi service for its guests for one hour every day. Then, the connection time can be set
as “1 hour” and reconnection time can be set as “1 day”. Thus, the guest can finish his job
within one hour and will not occupy the wireless network for a long time.
Note: Up to 300 Wireless Station records are supported by VigorAP.

The network signal for a single wireless access point might be limited by its coverage range.
Therefore, if you want to expand the wireless network in a large exhibition with a quick
method, you can install multiple access points with enabling the Roaming feature for each
AP to reach the purpose of expanding wireless signals seamlessly.
These access points connecting for each other shall be verified by pre-authentication. This
page allows you to enable the roaming feature and the pre-authentication.
Available settings are explained as follows:
Item Description
AP-assisted Client
Roaming Parameters
When the link rate of wireless station is too low or the signal
received by the wireless station is too worse, VigorAP 920RP
will automatically detect (based on the link rate and RSSI
requirement) and cut off the network connection for that wireless
station to assist it to connect another Wireless AP to get better
VigorAP 920R Series User’s Guide

signal.
Minimum Basic Rate – Check the box to use the drop down list
to specify a basic rate (Mbps). When the link rate of the wireless
station is below such value, VigorAP 920RP will terminate the
network connection for that wireless station.
Disable RSSI Requirement - If it is selected, VigorAP will not
terminate the network connection based on RSSI.
Strictly Minimum RSSI - VigorAP uses RSSI (received signal
strength indicator) to decide to terminate the network connection
of wireless station. When the signal strength is below the value
(dBm) set here, VigorAP 920RP will terminate the network
connection for that wireless station.
Minimum RSSI - When the signal strength of the wireless
station is below the value (dBm) set here and adjacent AP (must
be DrayTek AP and support such feature too) with higher signal
strength value (defined in the field of With Adjacent AP RSSI
over) is detected by VigorAP 920RP, VigorAP 920RP will
terminate the network connection for that wireless station. Later,
the wireless station can connect to the adjacent AP (with better
RSSI).
With Adjacent AP RSSI over – Specify a value as a
threshold.
Fast Roaming
(WPA2/802.1x)
Enable – Check the box to enable fast roaming configuration.
PMK Caching - Set the expire time of WPA2 PMK (Pairwise
master key) cache. PMK Cache manages the list from the
BSSIDs in the associated SSID with which it has
pre-authenticated. Such feature is available for WPA2/802.1
mode.
Pre-Authentication - Enables a station to authenticate to
multiple APs for roaming securer and faster. With the
pre-authentication procedure defined in IEEE 802.11i
specification, the pre-four-way-handshake can reduce handoff
delay perceivable by a mobile node. It makes roaming faster and
more secure. (Only valid in WPA2)

20 MHz- the device will use 20MHz for data transmission and
receiving between the AP and the stations.
Auto 20/40 MHz – VigorAP will scan for nearby wireless AP
to determine which channel width (20MHz or 40MHz) shall be
used to meet the air situation. Usually, 40MHz would have
better performance under the clean wireless environment (e.g.,
less wireless traffic / contention). When the air condition is not
satisfied (e.g., dirty air), 20MHz will be used by VigorAP
automatically to ensure smooth network transmission.
Fragment Length
Set the Fragment threshold of wireless radio. Do not modify
default value if you don’t know what it is, default value is
2346.
RTS Threshold
Minimize the collision (unit is bytes) between hidden stations
to improve wireless performance.
Set the RTS threshold of wireless radio. Do not modify default
value if you don’t know what it is, default value is 2347.
Country Code
VigorAP broadcasts country codes by following the 802.11d
standard. However, some wireless stations will detect / scan
the country code to prevent conflict occurred. If conflict is
detected, wireless station will be warned and is unable to make
network connection. Therefore, changing the country code to
ensure successful network connection will be necessary for
some clients.
Auto Channel

WMM is an abbreviation of Wi-Fi Multimedia. It defines the priority levels for four access
categories derived from 802.1d (prioritization tabs). The categories are designed with
specific types of traffic, voice, video, best effort and low priority data. There are four
accessing categories - AC_BE , AC_BK, AC_VI and AC_VO for WMM.
Available settings are explained as follows:
Item Description
WMM Capable
To apply WMM parameters for wireless data transmission,
please click the Enable radio button.
APSD Capable
APSD (automatic power-save delivery) is an enhancement over
VigorAP 920R Series User’s Guide
164
the power-save mechanisms supported by Wi-Fi networks. It
allows devices to take more time in sleeping state and consume
less power to improve the performance by minimizing
transmission latency.
The default setting is Disable.
Aifsn
It controls how long the client waits for each data transmission.
Please specify the value ranging from 1 to 15. Such parameter
will influence the time delay for WMM accessing categories.
For the service of voice or video image, please set small value
for AC_VI and AC_VO categories For the service of e-mail or
web browsing, please set large value for AC_BE and AC_BK
categories.
CWMin/CWMax
CWMin means contention Window-Min and CWMax means
contention Window-Max. Please specify the value ranging from
1 to 15. Be aware that CWMax value must be greater than
CWMin or equals to CWMin value. Both values will influence
the time delay for WMM accessing categories. The difference
between AC_VI and AC_VO categories must be smaller;
however, the difference between AC_BE and AC_BK categories
must be greater.
Txop
It means transmission opportunity. For WMM categories of
AC_VI and AC_VO that need higher priorities in data
transmission, please set greater value for them to get highest
transmission opportunity. Specify the value ranging from 0 to
65535.
AckPolicy
“Uncheck” (default value) the box means the AP will answer the
response request while transmitting WMM packets through
wireless connection. It can assure that the peer must receive the
WMM packets.
“Check” the box means the AP will not answer any response
request for the transmitting packets. It will have better
performance with lower reliability.
ACM
It is an abbreviation of Admission control Mandatory. It can
restrict stations from using specific category class if it is
checked.
Note: VigorAP 920RP provides standard WMM configuration
in the web page. If you want to modify the parameters, please
refer to the Wi-Fi WMM standard specification.

Airtime fairness is essential in wireless networks that must support critical enterprise
applications.
Most of the applications are either symmetric or require more downlink than uplink capacity;
telephony and email send the same amount of data in each direction, while video streaming
and web surfing involve more traffic sent from access points to clients than the other way
around. This is essential for ensuring predictable performance and quality-of-service, as well
as allowing 802.11n and legacy clients to coexist on the same network. Without airtime
fairness, offices using mixed mode networks risk having legacy clients slow down the entire
network or letting the fastest client(s) crowd out other users.
With airtime fairness, every client at a given quality-of-service level has equal access to the
network's airtime.
The wireless channel can be accessed by only one wireless station at the same time.
The principle behind the IEEE802.11 channel access mechanisms is that each station has
equal probability to access the channel. When wireless stations have similar data rate, this
principle leads to a fair result. In this case, stations get similar channel access time which is
called airtime.
However, when stations have various data rate (e.g., 11g, 11n), the result is not fair. The
slow stations (11g) work in their slow data rate and occupy too much airtime, whereas the
fast stations (11n) become much slower.
Take the following figure as an example, both Station A(11g) and Station B(11n) transmit
data packets through VigorAP 920RP. Although they have equal probability to access the
wireless channel, Station B(11n) gets only a little airtime and waits too much because Station
A(11g) spends longer time to send one packet. In other words, Station B(fast rate) is
obstructed by Station A(slow rate).
To improve this problem, Airtime Fairness is added for VigorAP 920RP. Airtime Fairness
function tries to assign similar airtime to each station (A/B) by controlling TX traffic. In the
following figure, Station B(11n) has higher probability to send data packets than Station
A(11g). By this way, Station B(fast rate) gets fair airtime and it's speed is not limited by
Station A(slow rate).
VigorAP 920R Series User’s Guide
167
It is similar to automatic Bandwidth Limit. The dynamic bandwidth limit of each station
depends on instant active station number and airtime assignment. Please note that Airtime
Fairness of 2.4GHz and 5GHz are independent. But stations of different SSIDs function
together, because they all use the same wireless channel. IN SPECIFIC ENVIRONMENTS,
this function can reduce the bad influence of slow wireless devices and improve the overall
wireless performance.
Suitable environment:
(1) Many wireless stations.
(2) All stations mainly use download traffic.
(3) The performance bottleneck is wireless connection.
Available settings are explained as follows:
Item Description

Station Control is used to specify the duration for the wireless client to connect and
reconnect VigorAP. If such function is not enabled, the wireless client can connect VigorAP
until it shuts down.
Such feature is especially useful for free Wi-Fi service. For example, a coffee shop offers
free Wi-Fi service for its guests for one hour every day. Then, the connection time can be set
as “1 hour” and reconnection time can be set as “1 day”. Thus, the guest can finish his job
within one hour and will not occupy the wireless network for a long time.
Note: Up to 300 Wireless Station records are supported by VigorAP.

The network signal for a single wireless access point might be limited by its coverage range.
Therefore, if you want to expand the wireless network in a large exhibition with a quick
method, you can install multiple access points with enabling the Roaming feature for each
AP to reach the purpose of expanding wireless signals seamlessly.
These access points connecting for each other shall be verified by pre-authentication. This
page allows you to enable the roaming feature and the pre-authentication.
Available settings are explained as follows:
Item Description
AP-assisted Client
Roaming Parameters
When the link rate of wireless station is too low or the signal
received by the wireless station is too worse, VigorAP 920RP
will automatically detect (based on the link rate and RSSI
requirement) and cut off the network connection for that wireless
station to assist it to connect another Wireless AP to get better
signal.
Minimum Basic Rate – Check the box to use the drop down list
to specify a basic rate (Mbps). When the link rate of the wireless
station is below such value, VigorAP 920RP will terminate the
network connection for that wireless station.
Disable RSSI Requirement - If it is selected, VigorAP will not
terminate the network connection based on RSSI.
Strictly Minimum RSSI - VigorAP uses RSSI (received signal
strength indicator) to decide to terminate the network connection
of wireless station. When the signal strength is below the value
(dBm) set here, VigorAP 920RP will terminate the network
connection for that wireless station.
Minimum RSSI - When the signal strength of the wireless
station is below the value (dBm) set here and adjacent AP (must
be DrayTek AP and support such feature too) with higher signal
strength value (defined in the field of With Adjacent AP RSSI
over) is detected by VigorAP 920RP, VigorAP 920RP will
terminate the network connection for that wireless station. Later,
VigorAP 920R Series User’s Guide

the wireless station can connect to the adjacent AP (with better
RSSI).
With Adjacent AP RSSI over – Specify a value as a
threshold.
Fast Roaming
(WPA2/802.1x)
Enable – Check the box to enable fast roaming configuration.
PMK Cache Period - Set the expire time of WPA2 PMK
(Pairwise master key) cache. PMK Cache manages the list from
the BSSIDs in the associated SSID with which it has
pre-authenticated. Such feature is available for WPA2/802.1
mode.
Pre-Authentication - Enables a station to authenticate to
multiple APs for roaming securer and faster. With the
pre-authentication procedure defined in IEEE 802.11i
specification, the pre-four-way-handshake can reduce handoff
delay perceivable by a mobile node. It makes roaming faster and
more secure. (Only valid in WPA2)

When the local client and remote server are required to make certificate authentication (e.g.,
Radius EAP-TLS authentication) for wireless connection and avoiding the attack of MITM,
a trusted root certificate authority (Root CA) will be used to authenticate the digital
certificates offered by both ends.
However, the procedure of applying digital certificate from a trusted root certificate authority
is complicated and time-consuming. Therefore, Vigor AP offers a mechanism which allows
you to generate root CA to save time and provide convenience for general user. Later, such
root CA generated by DrayTek server can perform the issuing of local certificate.
Root CA can be deleted but not edited. If you want to modify the settings for a Root CA,
please delete the one and create another one by clicking Create Root CA.
Click Create Root CA to open the following page. Type or choose all the information that
