Thanks, chaps. Have checked PC settings and they are as follows:
USBCM351000 (cable modem): 00 DO 59 X X X
IP address 80.7.X.X
subnet mask 255.255.255.0
default gateway 80.7.X.X
Only other thing I can find is
PPP adapter which just has 44-45-53-X-X-X as the Adapter Address.
This looks to me as if the ethernet card is not installed properly. I have got another card which I'll pop in and see how things look then. Any other ideas?
