anyone else experience this problem? last night i hooked up the usb ethernet adapter to connect the air to my old powerbook g4. changed settings to never sleep on both machines. started the migration, air said it would take 4+ hours, confirmed that it indeed started and then i went to bed. this morning an alert popped up on the air saying the was a problem with a connection (with only an hour remaining!) nothing had been moved, changed, etc. tried to start it again after restarting both machines and now when it tries to connect it says there's an error with the connection. anyone else experiencing similar problem? note: not sure if this has happened to you, but it helped to turn off airport on both machines before migrating via ethernet.
