How long have you waited after getting the new MAC address added? These things can take up to 24 hours, IIRC. You might have some success by powering off the cable modem (physically unplugging it from both the wall, *and* unscrewing the cable connection), waiting 5-10 minutes, and then trying again[1]. If you're desperate you could always just switch NICs to make sure things work. I assume you've already checked all the obvious stuff (cables, duplex settings, routing tables, and so on...)?

You're pretty much correct. I've found that switching the modem off, then swapping the machine and powering up with the new nic in place does the trick. Their hinder^Whelp pages suggest releasing the dhcp lease before doing that but I've never found it necessary. 'ipconfig /release' on a win2k box. You know that you can register MACs directly via the webshite ? Check with the working machine and have a look at http://selfcare.blueyonder.co.uk/PInfranetServlet?page=p_list_mac_addrs&loadBean=yes You'll need the username and password that they sent you when you signed up. It's *much* quicker than talking to the helldesk ! Simon. -- "Oh no, not again."

Re: Telewest + Linux + MAC(?) oddness
Thanks everyone (incl. Paul Hammond who answered offlist)! In the end I powered down the Windows box Tuesday, came in Wednesday and switched off the cable modem for a few minutes and then rebooted the linux box with the modem back on. It grabbed an IP and is working fine. Which of those did it I'm not sure but it's working finally.
