Descripción:
Unstable connection (Trisquel 8, kernel 4.4)
(Same issue with 2 devices) The connection is very unstable : it disconnects after some minutes. Then I need to disable the wifi and re-activate it to be able to browse the web again, until the next time some minutes later.

Power management for WIFI is disabled :

iwconfig | grep Power
lo        no wireless extensions.

enp4s0f1  no wireless extensions.

          Bit Rate=72.2 Mb/s   Tx-Power=20 dBm   
          Power Management:off

Workaround : use the following driver (better because muche more stable).
