you won't be able to get online when you use another network adaptor to connect to your cable modem as ntl stores the mac address of your original adaptor on its dhcp server. i have seen people saying that they need to call ntl to notify the change in mac address. actually you can change the mac address yourself without bothering ntlers.

you need win2k/xp/2k3 to do this (think linux or mac can also do it but not sure what the command is. anybody?). after installing the new network adaptor go to its hardware properties (for example via the device manager) and go to the advanced tab. then select the item called 'Local Administered Address' on the left list and write the original mac address in the 'value' field on the right, like '0123456789ab' and then click ok. not too sure whether restarting is necessary, probably not. do 'ipconfig' in command console and you see that the mac address has been changed to the orignal one!
