I was until recently using the XP64 driver by disabling signed drivers. This has been workign for months but since the latest wave of updates from windows-update the drivers stopped working. I tried reinstalling but to no avail.
I got on this forum and was looking for a solution since i LIVE off this thing for WOW (Really ui cant play without it anymore) but there was nothing new. In panic I started googling for a solution and found the thing I would not have thought would happen has happened.. http://www.belkin.com/uk/support/article/?lid=enu&pid=F8GFPC100&aid=7884&scid=293
Drivers for Vista from belkin themselves, released today.
I havent had a chance to test since I'm at work so please follow up with results if you do.
