Also, keep in mind wireless N products do not nessecarily always guarantee better speeds. I found this out recently after trying out a few products. Go to cnet and search for their wireless N comparison review’s. The name brands you would think are better (linksys/netgear) actually gave me slower speeds then g w/ speedbooster. After going to that site, i actually got a dlink xtreme gigabit router and dlink xtreme card, and i’m still only getting around 70-100 mbps, downloads. For some reason network transfers are still a little slower than that. But even thats a lot faster, and way more stable then the netgear gigabit router was offering.
I would highly suggest going to cnet and reading on what card to buy/what chipset is going to give you the best results.
