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.

security.
