When I say "Turn Off" in the network manager, the syslog shows garbled
content like a mismanaged buffer or uninitialized memory. I have
attached the part of the syslog and a hexdump of the garbled two lines.

Title:
  2357:0100 USB Wifi TP-Link WN8200ND cannot associate to access points

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The Usb Wifi dongle TP-Link WN8200ND (rtl8192cu driver) does not
  connect with a default 14.04 trusty updated one or two days ago from
  the internet.

  If I add the dkms module that replaces the builtin driver (see
  instructions and source code in [1]) then I can connect to some access
  points (like my cellphone tethering access point) but not to other
  access points where my laptop connects without any problems.
