Have you ever tried using an Apple AirPort Extreme? That's the router we're running with at home and it's been damn amazing. I haven't had to touch the thing since I bought it 1.5 years ago, and it's only been off three times during the time I've had it (all due to power outages). It's also ridiculously fast; I get almost all of my allocated throughput over Wi-Fi. It's amazing.
