Network-manager crashing

[João Gabriel]

My Network Manager was working well, but in 15/jun/17, I lost controlability over my hardware.

Now I can activate wifi through network-manager icon, but it doesn't display any network.

I can see it is activated through command line:

    nmcli -f in-use,ssid,bssid,signal,bars dev wifi

I can even connect to a network through command line:

    nmcli d wifi connect 14:D6:4D:39:8D:85

    Dispositivo "wlp2s0" ativado com sucesso com "85fcc7fb-60bd-47af-a9da-9381656ee2a3".

    ping 192.168.1.1

    PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

    64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=4.11 ms

But through graphical interface I cannot operate it.

When I'm connected through WiFi, the network-manager icon has changed.

Before the bug, it presented the common wifi icon, showing signal intensity of the connection.

Now it is presenting the icon of ethernet connection, when connect through WiFi.

When I open Network Connections and exclude some network, it doesn't remove it from the list until I close the window and open it again.

I have made an update on 14/jun, in the night. During all day of 15/jun I used my network without any problem. In the end of the say the problem began.

The packages updated were:

I have tried loading my previous kernel version (linux-image-4.8.0-53-generic), but it doesn't change the wrong behavior.

Restarting network-manager, reestablish normal behavior. But after suspend-awake, sometimes the bug returns.
