Don't get a DSL router, that would be useless since NTL broadband is delivered over cable. You'll need an ethernet router, not an adsl router., a very popular and feature packed ether router is the Linksys WRT54GS which has a built in access point so your devices can communicate with it wirelessly. It's very easy to set up and has a good wireless range because of the dual antennas.
