Chapter 10 Troubleshooting the Cisco Unified Wireless IP Phone 7925G Resolving Startup and Connectivity Problems If using static WEP, check the WEP key on the phone to be sure it matches the WEP key on the access point. Reenter the WEP key on the phone to be sure it is correct. Note If open authentication is set, the phone is able to associate to an access point although the WEP keys are incorrect or mismatched. Error Messages During Authentication If you see the following error messages, check these problems: Authentication failed, No AP found • Check if the correct authentication method and related encryption settings are enabled on the access point. • Check that the correct SSID is entered on the phone. • Check that the correct username and password are configured when using LEAP, EAP-FAST or Auto (AKM) authentication. • If you are using A WPA Preshared key or WPA2 Preshared Key, check that you have the correct passphrase configured. • You might need to enter the user name on the phone in the domain\username format when authenticating with a Windows domain.
