Hi guys. For anyone with poor gaming performance (and not only) I strongly suggest investingin the best router on the market, bar none. D-Link DGL 4300 (Wireless 108G Gaming Router). Even if the price is a little steep, it is worth it. Do some "shopping arround. For anybody interested here is the link: http://games.dlink.com/products/?pid=370.
My speeds are awesome (average 3.5 - 4MB). I am a tech support and I have seen a lot, it seems that the most common issue is reggarding your location and of course what "package you have (Lite, Full etc.).
