Operating System: Windows 98 (Note: might work with other versions of this os.)
Got it from the TP-LINK site for their TM-IP5600 modem. It works for 98 through Vista. The download extracts to a 'MOTOROLA' FOLDER. Then run SSETUP.EXE within that folder to install the driver files--don't go through 'reinstall driver', 'add new hardware' or 'new hardware found' to do the install. If you have other drivers already installed for it you should probably uninstall them before installing these.
