After apt-get upgrade a few days ago, my USB wireless adapter stop working, although it worked perfectly before.
Symptom: I can see (scan) the available wireless in the neighbourhood, but selecting my SSID (in the Network Manager GUI), and providing the (correct) password, it fails to connect. (I can access the wireless from other devices, smartphone and other PC).
Looking for solutions in forums, I set
