Every once in a while it seems my router (Linksys BEFSR81) stops working. All of the lights on the front indicate that everything is fine, but no web pages load my instant messaging program disconnects and I can't even get to the configuration screen for the router. The lights on the cable modem are also fine. The only way that I've found to get it working again is to reset the router by pulling the power cord and waiting a few seconds and pluging it back in. I've looked on the linksys support page and a few other message boards but no luck... any idea?
