[14e4:4365] (rev 01) Slow and unstable WiFi signal.

[ramiro]

With Ubuntu 16.04 my WiFi connection is really unstable. I have to reconnect all the time. Also, the WiFi signal icon's bars moves constantly. This has been going on for the last couple years.

The connection by cable works good, and also WiFi is working fine on other devices (computers and phones).
