You should meander into the section that has wifi routers and then pick the brains of whatever associate wanders by to help you. I could note that all the makers have web sites about setup and how to do this so I won't duplicate any content from linksys.com, dlink.com or netgear.com but I will say you should go shopping.
I have a PC which is hardwired to cable internet. If I buy a laptop how easy is it to network using a wireless system. Do I just need a router and something that plugs into the laptop. How much is this likely to cost and what are your recomendations as to which router, etc., to buy.
I run Win XP Pro on the PC and I presume I would have to have the new windows operating system on the laptop (Vista).
