send or receive data Perform the first four checks in “Cannot send or receive data.”
Check the Security Mode setting on the Wireless Primary Network
Page:
• If you enabled WPA and configured a passphrase on the SBG941,
be sure each affected wireless client has the identical passphrase.
If this does not solve the problem, check whether the wireless
client supports WPA.
• If you enabled WEP and configured a key on the SBG941, 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 SBG941.
• To temporarily eliminate the Security Mode as a potential issue,
disable security.
After resolving your problem, be sure to re-enable wireless security.
• On the Wireless Access Control Page, be sure the MAC address for
each affected wireless client is correctly listed.
