Vista - Net gaming problem

Hi, Recently my laptop was playing up, had viruses, etc., i went and got it fixed, and reformatted, before i had problems on my laptop i played CSS and WOW, easily

I installed WOW today and have come accross a few problems, but they are to do with the NET or VISTA, which of the 2 i do not know.

I installed WOW successfully, but it says cannot connect to server, when i try to get on to it, but my IE8 Browser works fine, so does my Windows Live Messenger, My internet status is Wireless, : Connected "Excellent"

I made sure all my firewalls were off and my account is set as Administrator

So i am starting to think it is something to do with my drivers for my laptop or Vista, ive tried to install additional drivers but no luck wat so ever

Also so you know, my m8 was able to run wow successfully the same day, so wow isnt the problem, because the servers were running and online
