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.

Wi-Fi 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 screen.

 If you enabled WPA and configured a passphrase on the

gateway, be sure each affected Wi-Fi client has the identical

passphrase. If this does not solve the problem, check if the

Wi-Fi client supports WPA.

 If you enabled WEP and configured a key on the gateway, be

sure each affected Wi-Fi client has the identical WEP key. If

this does not solve the problem, check if the client’s wireless

adapter supports the type of WEP key configured on the

gateway.
