I'm looking for a way to cover a big house with wi-fi. I've already tested with WRT54GL and it wasn't enough, so my idea is to buy 2 routers with good coverage and link them into bridge/repeater/WDS mode (I don't even know the difference to be honest). Since I've never done that before, I'm looking for an advice on which routers to buy and how to make it work altogether? At first, 2x Unifi LR LongRange was a promising solution, buy as far as I understand it, they both need to be physically connected into router with UTP cable, so that's out of equation because I can't drill holes into walls. How about 2x ASUS RT-N12 D1, would they do any good? They have pretty decent reviews and are also cheap, but do they even support signal repeating?
