[iBook Ben]

My situation is that at home I have a wired network which has two PCs on it sharing internet connection. I am able to connect my iBook by plugging into the network.
If I want to go wireless just with my iBook what hardware (in addition to an Airport card) would I need?

The network currently operates as a main PC with cable modem (2 Network Cards)which connects to a switch for the rest of the network.
Is there some sort of wireless hardware which I could simply plug into this switch where my iBook would normally do so?

Thanks in advance

The simpler solution is to buy a wireless router. These boxes include a gateway router, a switch (usually with 4 ports), and a wireless access point. Here's how it would go in your network:

Cable modem >> router WAN port

router LAN port >> PC #1
router LAN port >> PC #2
router wireless >> laptop

This simplifies things in a number of ways, including making it so you don't have to have any particular computer running to allow others to access the Internet. You have two ethernet ports left open for future use, and the access point usually is capable of supporting over 200 wireless clients! Cool?
