Our Home Network??

A friend of ours here in town is a networking and security consultant. This is a diagram of the LAN network that connects the computers he has in his house. We are going to talk to him about doing the same kind of thing. Right now I think I would like to have one computer upstairs in the office connected directly to the cable modem, and the other computer downstairs in the front room connected to the internet by a wireless LAN card. On his diagram that's how the three laptops on the right that are surrounding a picture of a radio tower are connected. The wireless connections have either a 100 foot range or a 50 foot range depending on which type of wireless we go with. Pretty cool stuff, huh?
