Networking :: How to setup a RT2500 card

I'm trying to instal a DWL-G122 USB Wireless card. I download de Rt2500 drivers source and install apt-get ad gcc system. I update agt-get too.

But when I do apt-get install build-essential linux-headers-2.4.26 the app returns:

could not find package linux-headers-2.4.26...

Somebody can help me? There are a linux-headers in dsl? anybody have the rt2500.o driver compiled?

Thanks for all!
