This is bizarre. I have five Macs in the house, all of which can see each other on the local wireless network...but...for some weird reason, none but when they try to connect, I get Connection Failed after several minutes of silence. When I click Connect As... in hopes of getting a login screen, nothing happens at all. Nada. Zilch. Zip. The sharing settings on the MacBook are identical to the ones on the other five. Of course, the MacBook can connect the other direction to everyone, including my brand spankin new MBP. Any clues, oh wise ones? Im stumped. What is it about getting into a simple MacBook that has two G4s and two MBPs scratching their heads?
