I used it in a small appartment so I never tested the range. It alwas covered the 800sqf well, but that's not saying anything. 802.11a is supposed to have worse range than b, and I suspect g, as g is supposed to have worse range than b. If you don't need a, I'd go with a G one at the moment. If on the other hand, the six overlapping networks slow your throughput to a crawl and it drops to zero whenever someone picks up their 2.4ghz phone, 802.11a is perfect.
