Query: I've seen three of these fail so far

I do some basic network consulting on the side, and have seen three WRT54G routers fail so far. One was mine, two were customers'. Of the ten or so that I've worked with, thats around a 30% failure rate. Not so good. When they work, they're great. The failures generally came after power outages, so it's likely to do with the power supply and/or conditioning in the power circuit in the router. In any event, I have not seen this failure rate in the D-Link, Netgear or Buffalo routers that I have worked with.
