I have a problem with Vista laptops not authenticating wirelessly to my 3COM WX-2200 wireless switch. It connects to it, but when you attempt to access the Internet you are supposed to be prompted with a username and password to authenticate into the switch. Then it will let you browse websites. People with Vista laptops are never prompted with this logon page. I get the typical IE7 Certificate error page saying, There is a problem with this website's security certificate. Then you click on "Continue to this website (not recommended)." After clicking on that, the page just times out and never loads. This is NOT the issue with anything other than Vista machines. On pre-Vista OS', I am prompted with the 3Com logon page after clicking on "Continue to this website (not recommended)".
I have tried Mozilla Firefox, just to see if it was IE settings, and disabled most security settings with no success. Anyone that comes into my building with a Vista machine cannot access the Internet wirelessly right now. Does anyone know what in Vista is not allowing this logon page to load?
