Sharing files/printers across a wireless network

[abc1]

Hi,

I currently have an Actiontec GT701-WG router (built in modem) connected via ethernet to my main computer. This router is also connected to the internet. Now the thing is, I have another computer that I'd like to set up a wireless network with. The second one has a Netgear WG311 wireless PCI card and I can share the internet connection perfectly but when I try to use windows 'Set up a wireless netowork' I just can't get it to set up so that I can share files and printers.

Could someone please explain the steps I need to take to do this? Is the router (connected via ethernet) on my main computer enough to share files?

Thanks.

[edit] both computers are using Windows XP SP2

Can you get internet with all the computers? Can you ping all the computers on your network? You don't need to use the wizard just to share files and printers.
