No stability issue.

[h1]Unstable connection (Trisquel 8, kernel 4.4)[/h1]
(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.

[p]Power management for WIFI is disabled :[/p]
[b]iwconfig | grep Power[/b]
[code]
lo no wireless extensions.

enp4s0f1 no wireless extensions.

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


[p]Workaround : use the following driver (better because muche more stable).[/p]
