Ok I have a wireless hub with my new broad band deal, but since discovered my PC isn't set up for wireless. What is the cheapest and easiest way to "hook up". Will I have to have a dongle protuding from the front of my PC tower. I want to use it for my lap top, so can I use the ethernet cable for the PC and wireless for the laptop. I think the laptop has a slot for an integral unit. Stupid question but I take it the wireless things for the lap top canme any make and don't have to be the smae as the router?
