So, I have a nice MDD 2003 G4 dual 1.25 with 2MB L3 Cache. Just got rid of the Belkin PCI FD57000 wireless-G card and replaced it with the USB netgear WG111v2. When I go into system profiler it gives me the following:
The system sees the Netgear device as a mass storage device i.e. hard drive. That is why the "OS 9 Drivers:No" is listed. There isn't support in OS 9 for USB 2.0, and I doubt Netgear has drivers available, but you could check with them.
