I am using a PLC plug now, but the wifi is still activated and still
crashes sometimes.

I will do as you suggest, as long as it does not prevent me from
writting my thesis.

Title:
  14e4:4353 Wi-Fi disconnects then cannot connect to any network --
  Broadcom BCM43224 bcma

Status in “bcmwl” package in Ubuntu:
  Incomplete

Bug description:
  I start my laptop, the network connects and I can use it well.

  Then after some time (hours, or days) the WIFI disconnects and can't
  connect to the network, nor any other WIFI network. The ethernet works
  fine however.

  There is a kworker process that hangs on CPU. NM asks me the WIFI key
  several times, and does not success in connecting the network.

  I then need to reboot my computer, as any "service network-manager
  restart" or "service networking restart" does not work.

  dmesg contains informations about an exception, I copied it in the
  attached .txt . Those lines are repeated several times.

  
  I think there are two bugs :
   - One in the WIFI driver that prevents connecting to the network
   - One in the network-manager that does not understand there is an internal bug and keeps trying to reconnect, while asking me the keyphrase. NM should know that the last connection failes because of an internal failure.
