Odd NTL Cable Modem problem

Hi, I'm helping a neighbour after a botched wireless install (NOT by me!). Neighbour has sent all wireless kit back and is connecting to NTL cable modem via USB port as they were previously. I suggested that ethernet might be better but I'm having the following problems connecting.

When I plug in the ethernet cables, the PC (running XP Pro, patched to date) says "Network adapter is aquiring IP address" [from cable modem], but times out with the message "Limited connectivity on this network" and does not pick up an ip address from the modem.

I have tried putting the required ip addresses into the NIC manually, and then I get a message saying "Connected at 100mps", but I cannot ping or browse the net, I have tried disabling the Mcafee and windows firewall, but still nothing.

I was beginning to wonder if NTL were looking at the MAC address of the NIC card and seeing it had changed from the USB Mac address was accepting the connection, but refusing to route traffic though it. The Cable Modem is a Motorola Model and my neighbour doesn't have any instructions as to its setup?

Hope this makes sense?

REmove all the ip settings and set it to obtain ip auto.

Unplug ntl modem from mains and turn off pc, plug in the modem and wait 30 secs for it to start up then turn on the modem.

the modem associates itself with a particular mac address so needs to be reset on the change from usb (yuk) to ethernet (good)
