well first question you have to ask is how fast is your internet connection. The second question you have to ask is how much bandwidth your game requires. The fastest you can ever go with a 54 mps connection is 28 mbps. This is assuming no interference and being right next to a good router. You can use Qcheck to benchmark it if your curious. I'd be willing to bet your broadband is about 5 mbps max so you want to stay above that. I use a 108 mbps super g network. I get about 30 mbps up close, 20 mbps 10 ft away through a wall. 17 mbps in the basement one floor down and one wall away. This is all with $25 network cards and a $80 DI-634M. Judging from the wireless charts it looks like Dlink DIR-655 is the best bet
