I am trying to share my internet connection between 2 macs, an iMac and a Powerbook, and about 75 feet of space. The iMac is receiving a direct-in ethernet connection from my modem. I have enabled internet sharing, however, is it even possible to use the airport to extend this signal? I cannot manage to get the Airport to recognize the shared signal; on the "join a network" page on the powerbook (mac #2) I have two options: 1. Computer or 2. Apple Home network (the airport's network from when i had previously configured it.) Note: the airport does not have ethernet plugged into it, I am merely trying to use this as a bridge between the only ethernet signal I have (the one in the iMac) and the one i need it to go to (the powerbook) did this make sense?
