I've been a customer since the Telewest days with an old but reliable SB4100 that had to be replaced recently. VM posted a new Ambit 256 and after registering it's MAC address with them over the phone I tested it was working with one of my PC's. Everything seemed fine and so I shut it down and switched off the modem to set up my Netgear WGR614v6 router. Now what I can't do is get the modem to accept anything but the MAC address of the network card of the first PC. I can get the router working by having it use that MAC address but not it's own or any other PC.

I know it's hardly a major issue but surely the thing should accept the MAC of the first thing it finds after powering up.

Signal levels seem normal on the modem and otherwise it seems to behave fine despite looking rather cheap and nasty.

It simply refuses to work unless what it's connected to is set to use that particular MAC address which at the moment isn't a problem but could be in future.

Has anyone got any ideas before I start with the joyful process of trying to get VM to help while avoiding all mention of the terrible word 'router' which sets them into such a tizzy?
