Suggestions to Correct
Verify the preamble type matches between controller and Clients. Try a different
setting.
Verify in Syslog there is not a high rate of decryption error messages. This could
indicate a device key is incorrect.
Verify the device is not in the "do not adopt ACL".
Verify Keyguard is set on the client if the Security/WLAN Policy calls for Keygaurd.
If Encryption is being used, verify the encryption settings on the Client and the
controller match.
If WEP Encryption is being used with non-Brocade Clients, ensure the key being
entered is in hexidecimal format and not a Passphrase.
If the controller is configured to use RADIUS authentication, check the RADIUS log
file for any failure information.
If you are using Authentication and/or Encryption on the controller, and the
previous troubleshooting steps have not fixed the problem, try temporarily
disabling Authentication and Encryption to see if that fixes the problem.
