Windows is validating identity for wireless network
Click on Properties once you select the wireless network that is having problems.
Click on the Authentication tab and now uncheck the Enable IEEE 802.1x authentication for this network box.
The previous chapter focused on the levels of authorization you should provide for users and devices based on your logical Security Policy.
You must type the name exactly as it appears in the Subject field of each RADIUS server certificate, or use regular expressions to specify the server name.
The complete syntax of the regular expression can be used to specify the server name, but to differentiate a regular expression with the literal string, you must use at least one “*” in the string specified.
If you disable this check box, client computers cannot verify the identity of your servers during the authentication process.
If server authentication does not occur, users are exposed to severe security risks, including the possibility that users might unknowingly connect to a rogue network.
