    This is Lion I presume.. losing its marbles.

     

    If a power cycle of the TC doesn't get it going.. give it the full treatment.

     

    Press and hold reset for about 10sec.. (I would say plug in by ethernet.. but you don't have one on MBA)

    Plug into another computer by ethernet to do setup for preference but if you must try if wireless now works.

     

    You will need to redo the setup..

     

    Use short names.. no spaces no special characters ie pure alphanumeric.. eg

     

    TC name.. TC

    Wireless name.. TC24ghz (no dot, no space)

    Set different name for 5ghz.. TC5ghz

    Set wireless to manual.. a/n - b/g

    Set wireless channels.. 1, 6, 11 for 2.4ghz try them in turn.. but this is hard to do by wireless.

     

    Update the TC.
