i love it when people have to be an ass, but don't have the courage to put their name behind it.

Are you absolutely certain it is the wifi? It could be your ISP. You didn't mention whether you were on DSL or Cable. I'm on cable, and I know that whenever my ISP resets my dynamic IP, my router locks up and I have to power cycle it. If it is always happening at the same time, it could be your ISP doing something on a regular schedule.
