Gateway Problem
Possible Solution
Cannot Access the
Internet
Check that all cable and power connections on your gateway
and computer are properly connected.
Check that the Power, Online, and Wireless LED icons on
the front panel are lit up solid.
Contact your service provider for assistance.
Wireless devices cannot
send or receive data
If the problem still continues after checking the coaxial cable
and Ethernet connections and your IP address, check the
Wireless Security Mode setting on the Wireless Primary
Network screen.
If you enabled WPA and configured a passphrase on the
gateway, be sure each affected wireless client has the
identical passphrase. If this does not solve the problem,
check if the wireless client supports WPA.
If you enabled WEP and configured a key on the gateway, be
sure each affected wireless client has the identical WEP key.
If this does not solve the problem, check whether the
client’s wireless adapter supports the type of WEP key
configured on the gateway.
