If you're considering it, don't. Or at least know there's a 50/50 chance of returning it. Pretty compact house -- dismal signal one room away. Ended up hardwiring CAT5 -- which is what I should have done all along. Second house in a row that I broke down in the end (though actually G with a newer laptop with integrated antenna would have solved the problem in house #1). The open-source Linksys replacement firmwares really help with signal with the ability to max out power.
Its somewhat amazing that I have three things under my TV with ethernet (PS2, Tivo, Media PC).
