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.
