I-4. Switch
The EW-7438AC includes a hardware slide switch
on the underside of the device which can switch
between normal, green mode and off as shown
in the table below. “Wi-Fi power” refers to the
strength of the extender’s wireless radio signal.
If you are using the extender in a small or
medium sized space, you may not need the full
power of the wireless radio. Try it, and determine
if you still have sufficient Wi-Fi coverage using
green mode. If so, you can save some energy.

100% Wi-Fi power
Green Mode

Power off
Tx power works in conjunction with the Tx power setting in
the web-based configuration interface (Advanced
2.4GHz
Wireless/5GHz Wireless). The switch is the primary setting
and the Tx power value will be a percentage of the slide
switch setting. E.G If the slide switch is set to Green Mode
(25%) and Tx power to 75%, the overall output will be 75% of
25%.

I-5. WPS Setup
The WPS button is a quick and easy method to establish a secure connection
between your EW-7438AC and wireless router/access point.
If your wireless device supports WPS (Wi-Fi Protected Setup) then you can use
this method to setup your wireless extender in extender or adapter/bridge
mode, instead of the setup wizard described in II. Installation.
Please do not hold the WPS button for too long – this may reset
your device.
1. Press the WPS button on your wireless
router/access point for the correct
length of time to activate its WPS.
Please check the instructions for
your wireless device for how long
you need to hold down its WPS
button to activate WPS.
2. Within two minutes, press and hold
the WPS button on the wireless
extender for two seconds. The
extender’s blue WPS LED should flash
to indicate that WPS is in progress.
3. The devices will establish a connection.
The extender’s blue WPS LED should
display on for 30 seconds to indicate a
successful connection.
The extender can establish either a 2.4GHz or 5GHz connection
using the WPS button. By default the extender will establish a
5GHz connection where available. Use iQ Setup to extend both
2.4GHz & 5GHz together.
6
I-6. Reset to Factory Default Settings
If you experience problems with your extender or if you want to change the
extender to a different operating mode, you can reset the device back to its
factory settings. This resets all settings back to default.
1. Press and hold the WPS button for at least 10 seconds and release when
the white power LED is flashing.
2. Wait for the extender to restart. The extender is ready for setup when the
white power LED displays on.

II. Installation
The EW-7438AC has three different operating modes:
Wi-Fi Extender
The device connects wirelessly to your existing network
and repeats the wireless signal.
Location: The best location for your extender is roughly
in the middle between your existing wireless
router/access point and the dead zone. The extender
needs to receive a good Wi-Fi signal from your
router/access point.
Wi-Fi Bridge
(Wi-Fi
Adapter)
The device connects to an Ethernet device such as a
games console or smart TV via Ethernet cable and
provides wireless Internet access for that device.
Location: Within Wi-Fi coverage, close to your wired
network device.
Wi-Fi Access
Point
The device connects to an existing router via Ethernet
cable and provides wireless Internet access for your
network devices.
Location: Connected to your router via Ethernet cable.
1. Plug the EW-7438AC into a power socket.

2. The white power LED will flash while the extender is starting up. The
device is ready when the white power LED displays on.
3. Use a Wi-Fi device to connect to the SSID “EdimaxEXT.Setup **”. The last
two ** characters are unique according to your device.
If you are using a computer, please disconnect any Ethernet
cables.

select “Yes, I need a Range Extender” to continue setup as a Wi-Fi
extender.
11
6. Follow the on-screen instructions for your selected mode to complete
setup. You can configure the product for 2.4 GHz and/or 5GHz Wi-Fi. Refer
to the appropriate chapter for each mode below if you need more help.

Notice According to GNU General Public License Version 2
This product includes software that is subject to the GNU General Public License version 2. The program is free software and
distributed without any warranty of the author. We offer, valid for at least three years, to give you, for a charge no more
than the costs of physically performing source distribution, a complete machine-readable copy of the corresponding source
code.
GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General
Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free
for all its users. This General Public License applies to most of the Free Software Foundation’s software and to any other
program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser
General Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make
sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive
source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that
you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender
the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you
modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights
that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms
so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal
permission to copy, distribute and/or modify the software.
Also, for each author’s protection and ours, we want to make certain that everyone understands that there is no warranty for
this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they
have is not the original, so that any problems introduced by others will not reflect on the original authors’ reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a
free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have
made it clear that any patent must be licensed for everyone’s free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License. The ‘“Program’“, below, refers to any such program or work, and a
‘“work based on the Program’“ means either the Program or any derivative work under copyright law: that is to say, a work
containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language.
(Hereinafter, translation is included without limitation in the term ‘“modification’“.) Each licensee is addressed as ‘“you’“.
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The
act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a
work based on the Program (independent of having been made by running the Program). Whether that is true depends on
what the Program does.
1. You may copy and distribute verbatim copies of the Program’s source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep
intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the
Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in
exchange for a fee.
