    So we have a Time Capsule setup. Old Macbook Air connected to it.

    Bought new Air. Originally they had the same name in Sharing "Vanessa's Macbook Air".

    Old Air works. As soon as new Air turned on, old Air gets kicked from the network, and is told none of the favorite networks are available, and can't rejoin the Time Capsule's network.

    As soon as new Air goes to sleep, BAM old Air is on the network.

    So I changed the names in Sharing tab of system preferences to "Vanessa's MBA 13" and "Vanessa's MBA 11" respectively. I also used DHCP to reserve each a different IP by MAC address. So one is and the other is

    So now it should work right? Nope. If the new macbook joins the network the old one is immediately kicked off. It doesn't happen the other way around.

    Also, the Time Capsule backup for the Old Air is corrupted, and Time Machine said it had to create a new backup and just toast the old one.

    What the HECK is going on?!! I'm completely stumped!

    I would call apple support. They are awesome with problems like this.

    Problem turned out to be....



    My 2.4gHz audio/video transmitter! It was clashing on the same channel as the time capsule and the new air was just enough to be the straw that broke the old air's back for wi-fi noise/rejection.

    Changed channel on audio/video transmitter and everything works again.

    The AppleCare rep I got was an absolute networking genius. I'm a fairly technical geek, but this guy's networking expertise made me look like a 3 year old. THAT is the kind of experience you want when you call technical support. A+

    Very nice, I'm impressed. A problem like that is very hard to catch, especially over the telephone... Great it worked out :)
