Here’s how to connect to your wireless router if you are getting this message.First, click on the wireless icon in your taskbar and under Related Tasks, choose Change advanced settings.Also, since I was able to connect from my laptop with no problem, it led me to believe it was something wrong with my desktop.After about 30 minutes of fiddling around with various settings, I was able to figure out what the problem was.I configured the IAS policy to grant access to Domain Computers, Authentication is set to PEAP and uses a private cert issued by our CA, the other profile settings are all default.The client settings on the laptop match the IAS settings and the certificate is definately installed.I moved the selection tab to WPA2 only and keep the rest the same and no luck. Ok so I setup the router to only transmit wireless N and to use WPA2 only.
If the box was checked, then that was why you were getting the “unable to find a certificate to log you on to the network” message because Windows is looking for one, but your wireless router is not setup for certificate security. Once I unchecked that box and tried to reconnect to the wireless network, everything worked fine! WPA2 is supported as i can connect to WPA2 personal APs. During the connection it flashes that it "connected" for a second then goes to "Validating Identity" which it eventually timesout on.I am using the Windows Wireless Connection Manager. On a couple of occasions I've seen that particular AP (don't know what firmware) suddenly stop attempting to authnenticate clients (it never sends any RADIUS requests) and power-cycling the AP "fixes" the issue.Ok so I setup the router to only transmit wireless N and to use WPA2 only.When I try to connect using the windows zero configuration utility it gets stuck validating identity.
