2 - GET THE DWL-122 DRIVER AND INSTALL IT
I found the driver, with the help of versiontracker.com, at this address:
ftp://203.126.164.142/driver/DWL-122_MAC_OSX.zip

Allow the Mac to reboot when the install is finished.
Nothing complicated at this step, just follow the on-screen instructions. Don't forget to unplug the Linksys wl-140 befor you start.
After this is done, we must
find the "kernel extension" that are to be modified.
