** Description changed:

+ According to 
+ 
https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoofing-in-networkmanager-1-4-0/
+ there is a new privacy feature in the new version of NetworkManager.
+ This privacy feature can cause some USB WiFi adapters to stop working
+ while they used to work with older versions of NetworkManager (Ubuntu 16.10 
or older).
+ 
+ The purpose of this privacy feature is to get your computer to report a new 
random MAC address whenever you connect to a WiFi network.
+ This privacy feature is especially useful when you connect to public WiFi 
networks, so that the operators cannot identify you when you connect multiple 
times.
+ 
+ The downside of this privacy feature is that some USB WiFi adapters misbehave 
when NetworkManager tries to change their MAC address repeatedly. 
+ The result is that those USB WiFi adapters cannot connect anymore to the WiFi 
 network.
+ 
+ Original report follows:
+ 
  My Panda USB wi-fi adapter works just fine on 16.10, but when I try to
  connect to my wi-fi router in 17.04, GNOME network manager reports
  "Connection failed." I did some tinkering, and noticed that my MAC
  address for my wifi adapter, according to GNOME, is DIFFERENT every time
  I make it forget my wifi settings and try to reconnect. Weird, right?
  Any leads on a possible fix or work-around?
  
  I'm running the latest beta of Ubuntu GNOME 17.04, kernel
  4.10.0-19-generic, GNOME 3.24.0.
