I THINK the answer is no - you can't use the router part. What you can do though (I think) - and this is probably what Belkin's support centre mean - is connect ONE PC wirelessly and connect the cable modem to a hard-wired LAN port, thus giving ONE PC wireless internet access. (You'd need to turn off the DHCP function, so the PC gets it's IP address from NTL, rather than from the router). If I'm wrong, no doubt someone will be along to correct me.

by the way.
