I have a Linksys WRT54GL here, with dd-wrt (v23) running on it, and I'm very pleased with it. I can change the output power to increase coverage which is nice, however at the normal levels it covers our 210m^2 house without any issues.

It's also been very reliable, haven't actually had to reset it for any reason yet, it's only ever been reset to single out a network problem in other equipment.

The wireless portion of it has never dropped a connection on me either.

Overall I'm very happy with it.
