So heres the story. My wrt54gs v4 was working just fine for about a month then bang stops working.Still have the wireless connections just fine..... Logged into the firmware and its not connecting to my isp comes up saying "cannot establish ip from pppoe server". So I reset the modem and router still same thing. I upgraded the firmware to 1.05.2 and bam it works again for about 30 minutes. Now its down again. I tried without the router just a direct connection from one computer to the dsl modem and it works just fine so i know its not an isp problem. Anyone have an ideas of whats causing this or what I should do?
