Problem

Possible Solution

 

 

Wireless client(s) cannot 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 SBG901, 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 SBG901, 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 SBG901.

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.

Slow wireless transmission speed with WPA enabled

On the Wireless Primary Network Page, check whether the WPA Encryption type is TKIP. If all of your wireless clients support AES, change the WPA Encryption to AES.
