[SLUG] Cheap Linux/Windows wireless home networking options ?

[Rod Butcher]

I need to set up a wireless home network, essentially for training 
myself on networking. It needs to support a couple of Linux and Windows 
servers and clients such as laptops. Do I need a wireless router, or can 
I just plug a cheap PCI card into the server that will host the network 
? Can anybody recommend cheap Linux-compatible solutions available in 
Sydney ?
thanks
Rod
