Hey, it might work. If it were me, though, knowing how finicky wireless networking is, I'd cover my bases. Especially if I were running cable already, I'd just go all out and run it to the farthest points, then stick the access points at those locations. If you get a new AP/router, you may end up with something that has a different antenna design and signal range.

Does anyone here know about the properties of ac? I seem to recall that while n technically has greater range, it has more trouble with obstructions. Is that the case? How does ac do?
