I'm having a problem connecting my laptop to my wireless router. The error I am getting is "Windows was unable to find a certificate to log you on to the network".
you can give that a shot (but be alert for third parties connecting onto the wireless device). However, based on the error the Windows box is trying to use a security method not configured on the router, so turning off security on the router isn't likely to help. Need to find the setting in Windows which is making it want to use a certificate to negotiate the connection.
