yeah, NTL is cool for nix
i was on NTL broadband until i recently moved house
as long as you use the ethernet connection if your using the cable modem then you will be fine and dandy. if your using the set-top-box to get your bb, then its always an ethernet connection. either one will work with no problems at all.
just set your network up to use DHCP to get your ip addy and whatnot, and it will take care of itself. its a great service, and ive never had any problems with it at all, the only reason i had to switch to BT was cause i moved house.
you dont need the windows thingumy
you dont actually need the windows app for activation.
the only windows box i had here when i had the cable instaled was a way old p75 running win95. it wouldnt run the included software, and obviously it wouldnt run on the nix box. all you actually need to do is call up tech support and get the ip address of the 'registration page'. the account activation is little more than typing in the numbers on your introductory letter into a webpage and ntl activate your cable. its pretty painless, and any web-browser can do it.
