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.
