have wireless internet already.? A friend wants me to help her. She has a comp and a laptop that she want to connect. I think the laptop comes with a build-in wireless 802.11bg. When I check her laptop to see want I need to setup, it said to have wireless network adaptor, one for each computer on my network, and a wireless router. What specifically do I need and how many do I need in order to get internet connection onto the wireless home network that I'll setup? Thanks!
