I have read a lot of threads regarding firmware upgrade failures in WRT54GC model. Maybe another one was born... I have the 54GC a few month but never have it operate successfully. Each hour, too many disconnections. I got advice to upgrade firmware and found the Linksys official 1.02.8. During upgrade the wired computer stuck. I got none pingable router with yellow power led. I have tried most of the recommendations in this site: Using wired computer, Resetting the unit (30 sec & turned off), static IP address, lowering net speed (10T), TFTP utility but the 54GC refused to answer. Funny, I have the 54GL and it works perfect. I thought that the 54Gc would be nice for travels... Before I give up and say "No more bad product like Linksys 54GC" any of you have some idea what to do?
