If its a new laptop all you need is a wireless "G" access point. They are very easy to setup and get going by virtually anyone.
I can't stress this enough. BE SURE to enable security, at least WEP to keep people from accessing your network and or sniffing your traffic. When I'm bored I'll sometimes grab a laptop out of the office, fire up Ethereal and ride around town during my lunch hour. It would literally scare the hell out of people how many businesses have completely wide open wireless networks, using applications that transfer data in insecure ways.
Thanks! I've been slowly catching up on wireless security and am learning about disabling certain Windows components, but...
WEP ???
