I have been having a problem with my PowerBook's Ethernet port lately. Sometimes for no apparent reason it will stop working (not while it's working, but when I plug an Ethernet cable in). Sometimes it will not detect the Ethernet Cable and the Router on the other side, while sometimes it does. It has happened 4 times now and it happens at random. When I've had that problem I've tried to get it to work with 4 different cables, different routers, shutting down, restarting, and putting my PowerBook to sleep and still nothing. Suddenly (usually the next day), the port is functional again. Any ideas? EDIT: My PowerBook is a 1.5Ghz, 15" PowerBook with SuperDrive.
