Select Properties once you locate the wireless network causing the error.Step 5 Select the Authentication tab and uncheck the Enable IEEE 802.1x authentication for this network box.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. " From: Upgrade to SP3 and you should be able to connect to your network.
The client settings on the laptop match the IAS settings and the certificate is definately installed.
By default, 802.1X authentication on Window 7 consists of not only client authentication, but also server authentication, which requires the server (here is the Vigor AP) to provide certificate information to the client.
However, if the model or the firmware version does not support Certificate Configuration yet, we may set up the Windows client not to verify the server's identity, and still do 802.1X authentication with Vigor AP.

Step 7 Select the Association tab and uncheck the “The key is provided for me automatically” box, then select Network Authentication & Data encryption and type in the Network key according to the wireless settings on your router.
