you need to get what i think is called wireless keys, they are a little thing that looks like a thumb drive and it plugs into your usb port and you are good to go if you already have a wireless router.
first, you need to buy a "wireless router" for all the computers, then buy a "wireless G adapter" to install in your computers so they can pick up the wireless signal coming from the wireless router.
Use a router. Of course, the router depends on your PCs and connection speed.

For a 128kbps ++ speed Internet, and really good PCs, I suggest get one of the better routers (more expensive)

For a 56kbps / 29kbps and normal PCs, I suggest a cheaper router.

Also, routers require USB Adaptor (adapter???) of the same brand. These are the ones that will wirelessly spread your Internet as well as LAN over your PCs. Unless your PC came with its own wireless connection, you should get 1 or 2 of these.

Finally, the range counts. Remember that the further away the PCs are from each other, the less the speed of both LAN and internet.

I hope I answered your question.
I have 2 computers and I use a router!
You need to buy a router, either a cable or ADSL router(through tel. socket ), depending on your broadband connection. This router will be connected to the modem- to share internet connection wirelessly. Then for your computers, you need to buy a USB Wi-Fi adapter, or for laptop a PC card Wi-Fi adapter if your laptop lacks built-in Wi-Fi. Once your computers have the Wi-Fi adapter connected , it will connect to the router without wires to get online.
