Quite easily and IMO, it knocks the spots of ICS and is expandable so if you wanna add more PCs you can. Also, you don't need to have the PC on when the 2nd one wants to access the net.
There are several types you can get but I'd recommend one of a Belkin, Linksys or Netgear as they seem to be most reliable, as for protocols 802.11g is the best. You need one that doesn't have a modem in as ntl have provided you with one, they are usually called cable routers. There's threads you can find on (wireless) routers here:

and one on securing wireless here

which I can't emphasise the importance of enough.
If you look around online and find one you want anyone to take a look at then feel free to post back- likewise, if you get one and are experiencing setup issues...
