Wireless units stop working under OSX

So i have a MacBook white, from february 2009. recently the bluetooth unit ceased to exist when under mac OSX, but it works perfectly while bootcamping windows. when trying to access my wireless network, it asks for password, and when i provide password, it says (in swedish) that my "connection request has" - nothing more, for some reason. i guess that "Failed" or "timed out" should be the missing words here.

again, while under windows XP the wireless works flawlessly, which is good so i can rant about this here.
