Connecting Wireless Notebook to Wired Network

You can hardwire the laptop using its LAN port as long as you have a free port on the router. If she wants to connect wirelessly, you'll need to get a wireless Router if your's isn't but you can still hardwire you computer to it and the modem would connect to the router like it does now. I'm using a ZyXEL x-550 and really like it but Bufflalo, Netgear, Linksys, and D Link make good routers. I'd stick with b/g rather than n right now given they're still working on the n standard
