ok so I recently had my modem give up the ghost on me and want to use my desktop PC to play some PC specific video games. The problem is, that they require an active internet connection. There IS a wireless but I can't use a wireless adaptor as my computer has rejected every single one I've tried thus far. What I want to know is if I can use my macbook pro's airport as a modem, grabbing the wireless signal that it has no trouble connecting to, and sending it via a lan Router to my PC. Can that be done?
