Title:
  USB wi-fi dongles not working with latest updates

Status in linux package in Ubuntu:
  Confirmed
Status in network-manager package in Ubuntu:
  New

Bug description:
  Same laptop - two different network dongles (ASUS USB-N13 + Edimax
  cheap commonly used with RaspPis). Confirmed issue with xenial-updates
  and xenial-security versions. Going to try to force a downgrade to
  original xenial to see if it still happens.

  ASUS dongle -> $ inxi -Fxxrzc0 | pastebin
  https://gist.github.com/d926d05c2bd23226a9f4b4a593b9de65

  Edimax dongle -> $ inxi -Fxxrzc0 | pastebin
  https://gist.github.com/f76284151c225ae43af82de8439efe02

  
  They work fine w/ the 18.1 Installer/Live Boot.. They worked fine after the 
install.. when I did the latest update they broke.

  ^^^ note.. it attempts to connect to the wifi.. and manages a successful 
connection (my tomato router shows an assigned IP for the MAC of the wifi 
dongle).. but it fails in the process /before/ it saves the network name + 
password for auto connecting in the future... so at first this happened every 
time I plugged in the dongles because it would try to auto connect.. but if I 
deleted the saved network I could at least plug-in/remove the dongles (they 
would register with the USB hub) without issue. But once I attempted to connect 
/ provide creds / etc it would bomb. Initially I thought it was dhclient but I 
don't think it is. 

  Whatever else you need I can paste.
