I’m gonna say this first – don’t buy them.
It just pisses me off to walk into a Future Shop and see them sell these things under false marketing. Why false marketing? Because the “n” standard isn’t finalized yet, and manufacturers have been making products that might not work with the final standard.
The 802.11g standard has been here for a number of years, and we know that it works. People have been using it left right and centre… cities have based their entire wireless off it. Google had implemented it in San Fransisco. The 802.11n standard is not final. What does that mean? It means that when you buy your D-Link 802.11n router, and Linksys 802.11n wireless card, they might not work at their full rated speeds. With g products, this usually isn’t the case (you might find some incompatibilities, but usually from smaller name brands).
Anyways – it’s not a finished product. Don’t expect them to work as advertised, and don’t expect them to work with true Wireless-N products. $200 for an unfinished router is a waste of money.
