First-time NTL user trying to register without the CD, using my laptop via ethernet cable (provided by NTL) into cable modem, under Windows XP. Most of the modem lights are busy flashing but ipconfig/all always shows Ethernet adaptor IP address of all zeroes and won't connect to Registration site address. I have tried ipconfig/release and /reset, and turning off the cable modem several times and let it settle, but no change. Also tried alternative ethernet cable (but not USB as I want to connect the modem to a broadband router via ethernet, and anyway haven't got the USB drivers as they failed to deliver the CD on installation). So what is most likely cause of all zeroes ISP-side ip address?
