My new Linksys WRT54G router keeps disconnecting from the Internet (PPPoE connection). Sometimes it even happens when I'm actively surfing or downloading. There seems to be no pattern. Resetting or messing with the cables won't bring my connection back, though after a while (hours), it returns. The kicker is, the only way I can get my connection back right away is by unplugging my ethernet cable and putting it into my old router. The WAN signal lights up, then I plug back into my WRT54G and everything is fine. Anyone know what's happening? PS Latest firmware is installed.
