I guess that you cannot, unless you have a wireless router.http://www.microsoft.com/windowsxp/using/n...p/wireless.mspx
I don't do wireless, so I have no hands-on with it. I do have a wireless router, though
, I just use it as a wired router.
If it is your NIC, then it would seem that you just have to acquire a wireless router and set up the wireless network.
The best way to test that wired NIC...would be to remove it and replace it (temporarily) with another wired NIC that is known to be good. If that setup didn't work, it would be something other than the NIC (setup, etc.) on your system. Alternatively, you could temporarily move it to another system and see if it works there.
Sometimes it's convenient to have multiple computers
