I just updated my Software to the New Apple Extreme 2007-001 and once I did that my Macbook's Airport has gone to hell. The Airport Icon in my taskbar never turns black any more and when I click on it to turn on, it does nothing. I've gotten my internet to run wirelessly a couple of times by using the diagnostics, but the results are similar to throwing a dart in a dark room and hitting the right wall.
I would like to revert my airport to pre-february update, so if anyone knows how or is having similar problems, please respond.
