Common
Problems
LAN LED is Off
The Ethernet cable may not be connected or be damaged.
Make sure that the Ethernet cable is properly plugged in, or
replace it with another Ethernet cable.
PC/HUB switch is not set correctly.
The switch should be "in" if the Router is connected to a PC;
and it should be "out" if the Router is connected to a hub.
Verification and IP Address Problems
Getting a bad subnet address error.
The Router normally attempts to dynamically assign IP address-
es. Turn your static IP address off on your PC, then use the User
Manager to tell the Router that you will be using static IP
addresses. Then turn static IP addressing back on.
Getting a Verification Error.
Click Next on the error screen. You will be prompted to check
the most likely causes for the error. At any point in this process,
you can click on Retry to attempt to verify the Router again. If
you click on Done, you will exit the Install program.

The ADSL cable is not connected or has been damaged.
Ensure that the ADSL cable is fully plugged in, or replace it with
another telephone cable. Otherwise, contact your ISP.

Make sure that any filter or splitter that you received from your

Using the User Manager, make sure you have entered the proper
VCI/VPI values from your ISP. Otherwise, contact your ISP.
