I have my iBook hooked up to the net via ethernet. Is it possible that I could connect my PC to the internet by joining a wireless network emitted by my Mac? The reason is because I can carry my mac into another room, connect there, and then use the net on my PC. But my bulky PC laptop has to stay where it is due to setup/space restraints. So, any ideas suggestions, directions are more than welcome. I'm running leopard.
