I built a new computer and the only thing I need now is a wireless adapter. I would like to purchase one that can go into a PCI slot and is a N. The problem is, I don't know which one I should purchase. It has to be compatible with Windows 7 Professional 64bit and a WRT350 N Linksys Router. I'm a gamer and my computer is located a floor above the router and about 50ft away. Any suggestions?
I would stick with the same brand as the router for simplicity and compatibility.
Whether you will be happy with gaming over wireless is something you should consider -- there's an inherent loss with wireless and you are likely to encounter further loss if operating near the (realistic) limit of the wireless.
