This section describes common problems and offers solutions.
I don't understand the front panel status indicators
See Operation of Front Panel Indicators (on page 37), for more detailed information
on front panel LED status indicator operation and function.
The Wireless Gateway does not register an Ethernet connection
Try one of the following solutions:
Verify that your computer has an Ethernet card and that the Ethernet driver
software is properly installed. If you purchase and install an Ethernet card,
follow the installation instructions very carefully.
Verify the status of the front panel status indicator lights.
The Wireless Gateway does not register an Ethernet connection after connecting
to a hub
If you are connecting multiple PCs to the Wireless Gateway, you should first connect
the Wireless Gateway to the uplink port of the hub using the correct crossover cable.
The LINK LED of the hub will illuminate continuously.
The Wireless Gateway does not register a cable connection
The Wireless Gateway works with a standard, 75-ohm, RF coaxial cable. If you are
using a different cable, your Wireless Gateway will not function properly. Contact
your service provider to determine whether you are using the correct cable.
There is no dial tone when I lift the handset
Try the following solutions if you cannot hear a dial tone:
Your telephone wiring may be connected to the wrong RJ-11 port on the Wireless
Gateway. The Wireless Gateway has two telephone ports. Verify that you are
connected to the correct telephone port.
There may be a problem with your telephone set. Use a different telephone set
and listen to hear dial tone.
