I have a G4 iMac and a G3 ibook. Both use the same Airport sender for the internet. I have offered shared files in Limeiwre from both computers. On the iMac I can receive the iBook's shared files.When the files are downloaded, there is no connection. The Requery function comes up. I am unable to find the iMac's shared files at all on the iBook. The iBook is using OS X and the iMac 10.2.1. Is the probelm because both use the same Airport sender or is something else wrong? The Airport is connected to cable, through a cable modem.
