Validating identity in wireless
In this window make sure you are in the "Association" tab.
Please refer to the documentation of your vendor's card in order to turn it off as this may interfere with the procedure here documented.
Uncheck Varify the server’s identity by validating the certificate, then click the Configure button. Make sure the Automatically use my Windows logon name and password (and domain if any) checkbox is unchecked.
Check Specify Authentication mode and choose User Authentication.
I recenty switched from AT&T Uverse to Time Warner because AT&T Uverse could not support Cisco VPN Client.
If your network is Encrypted go on to step 6 otherwise Click ok and try to connect to your network again.
These are only needed when you first setup the wireless connection.
