Perform the first four checks in “Cannot send or receive data.”
Check the Security Mode setting on the Wireless > SECURITY — basic Page:
If you enabled WPA and configured a passphrase on the SBG900, 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 SBG900, be sure each affected wireless
client has the identical WEP key. If this does not solve the problem, check whether the client
wireless adapter supports the type of WEP key configured on the SBG900.
To temporarily eliminate the Security Mode as a potential issue, select None and click Apply.
After resolving your problem, be sure to re-enable wireless security.
On the Wireless > SECURITY — advanced Page:
Check whether you turned on Disable ESSID Broadcast. If it is on, be sure the network
name (ESSID) on each affected wireless client is identical to the ESSID on the SBG900.
Check whether you enabled Allow Only Listed Stations Access. If you did, be sure the
MAC address for each affected wireless client is correctly listed.
For detailed information, see “Setting Up Your Wireless LAN”.
