I had the same problem Mark and I unplug my WRT54G every once in a while too. It seems to help to unplug the radio too but I am not sure about that. This is my second WRT54G because the first one was defective. I called tech support at 1-800-326-7114 and they waltzed me through several tests before saying it was defective. They then sent me the packaging for return authorization and sent me a new one. They were very cool about the whole thing.
