I have two computers connected together via a crossed cable. They share the internet via a Telewest connection and internet sharing under XP Home (I have 2 NIC's on the main PC - one connects to the cable modem - the other connects to the second PC).

Both machines can share files, printers and internet access.

I have now bought a centrino based laptop and am trying to connect that to share the net.

I have added a netgear wireless card to the main machine and this now allows me to share files etc. but I cannot browse the web!

A techie at my local computer shop said I have to bridge the connections but when I try this on the main machine it says 'To create a Network Bridge you must select at least two network connections that are not being used by Internet Connection Sharing or the Internet Connection Firewall'.

Does anyone know if this is possible and how to do it?

I know a router is the best way but I would rather try everything before spending any more money.

Any advice would be appreciated.
