I have a Safecom SAMR-4114 wired ASDL modem router, that has been working fine. Recently I have been having a problem in that sometimes it can only keep up a connection for a couple of minutes before the router resets itself and I lose the connection. I the get the error 'A network cable is unplugged' appear at the bottom of the screen, it re-establishes the ADSL connection and then works again for a bit. I am using windows XP with just a single PC plugged into the router via an ethernet cable. Do I need a new router, a firmware upgrade, or could it be something else. Any help would be appreciated. Thanks in advance, Andy Baker
