The problem may be in the router itself, prehaps a faulty product. But I am more inclined to think it is the outdated copy of windows 2000 which you use. In my view 2000 was second to Windows ME in terms of faults, errors, recoginizing hardware, and what have you. I would take the router back to walmart and test with a new one, but if that does not help, then it may be time for you to upgrade. Have you tried getting the ps3 online even without the computer having an active connection? Give that a shot and if for some reason the ps3 grabs the signal then it is time to give in for sure man. And watch the router when you try to connect the ps3 to see if it even attempts to grab the wireless connection, the wireless light will start blinking rapidly if it does.
