Wireless Driver will definitely work on OS X 10.3 (Panther) and also claims to work for 10.2 (Jaguar) and 10.1 so it should cover all your needs. Simply run the installer then either kextload the extension or just reboot and specify the network to connect to in the new “Wireless Config” control panel and configure the new “Ethernet Interface” that will appear in the network control panel.
