help for ralink rt2500 cardbus reference card

could anyone please provide a download link for config2500.exe?

here's the problem: i've been wondering for the past couple of days why my wireless networking icon in the network connections is missing. i tried reinstalling my modem, but to no avail. then i found out that the problem wasn't in the modem but the network adapter. so i tried looking for drivers for my ralink rt2500 cardbus reference card, all of them didn't solve my problem. so i figured, why not download the last installed driver that worked: config2500. i tried searching all over the internet for this software for days now, still can't find one.

help.
