Unable to connect to any network

I have a CPU-Upgraded G4 Cube running Leopard. Up until today, I could access the Internet fine. Recently, I tried to poen a Web page, but it said I wasn't connected to the Internet. When I went to Network Preferences, SysPrefs crashed. Rinse and repeat, same story. I tried to enable AirPort, but nothing happens. I deleted /Library/Preferences/SystemConfiguration to no avail. What can I do short of reinstalling OSX? My CUbe has no DVD drive and I don't have a USB drive.

It could be a power related issue with your Power Management Unit (PMU) I don't know however, how to reset the PMU on a G4 Cube....

Try resetting your NVRAM. this is accomplished by shutting down your computer. Then during startup hold down Cmd, Option, P, and R

If this does not work let me know

Would that be the case if all three adapters (USB Ethernet, Ethernet, and AirPort) are visible in System Profiler?

hmmm it's still possible, but unlikely that it's the PMU.

However it could still be the NVRAM. you should try resetting that

I tried resetting both to no avail.
