One of my kids (#1) has a Mac notebook computer that automatically seeks networks and gives you the opportunity to log on to anything it detects. Kid #2 has a Windows XP laptop (Dell) that does not have that capacity. Is there anything I can buy for #2 that will give her computer something like #1?

I have a wire-based ethernet network in my house but this wireless thing I just haven't kept up with because I didn't intend to go that way. What can I do that will allow me to keep my network but give it wireless capability?
