I just started going wireless and I got one problem now: We got sub-areas in our school network, and you can't connect from one to the other. The Airport is hooked up to one of those sub-nets, the wired network is in another. I have a G4 which has AirPort & Ethernet connections, so that one can, thanks to OS X, access all the computers... is there any way to set the G4 up so it works as a router, so that the wired computers can access all the wireless?!? I know MacOS X has some great capabilities...
