Gateway Problem Possible Solution
Wireless devices cannot
send or receive data • If the problem still persists 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.
