KJben,
okay 2 ways to setup the belkin for NTL
1. (easy) switch off the ntl modem and leave it off for 5 mins, plug everything in the belkin and thats done)
2. (harder) log into the router via your main pc that always works on the NTL modem (default ip is
http://192.168.2.1) then go to "internet wan" and select Connection Type.
You'll get a list of connection types there, select Dynamic IP press next and on the following page it'll ask for hostname, ignore this and below it says Change wan MAC ADDRESS, press that and then on the page that you get after that press CLONE.
after either of the 2 steps I've given you you should have connection.
