My download speed while in vista is about 50% of what it is on xp. I have a dual boot xp which average 490kbs on the download while vista got around 250kbs. This was the exact same file from same website, tested out a few other files with all same result. I updated the lan drivers thinking it might be that, didn't do anything so I'm outta ideas. Wanna leave reformat and screw vista as last resort as it is my main OS with all my crap on it. Also would this effect pings in online gaming? is that related to download or upload? Thanks guys.
