I have found the exact same problem than Manuel Dias (#24) but within a Samsung N150 Plus netbook.
A Lubuntu 13.10 install on the same hardware (Broadcom BCM4313) had solid wireless.
I was not able to get any wireless switched on again, no matter wich trick o change I tried.
But finally Hayden Skinner advice (#25) allowed me to get wireless on again. It works nicelly again but with the wicd interface which you have to start from the main Internet menu to configure it the first time.
