Broken state.

pavel@amd:~$ nmcli dev
DEVICE  TYPE      STATE        CONNECTION
eth1    ethernet  unavailable  --
lo      loopback  unmanaged    --
wlan0   wifi      unmanaged    --
pavel@amd:~$ nmcli radio
WIFI-HW  WIFI     WWAN-HW  WWAN
enabled  enabled  enabled  enabled
pavel@amd:~$ uname -a
Linux amd 4.16.0-rc5-next-20180314+ #31 SMP Thu Mar 15 14:27:19 CET
2018 i686 GNU/Linux

Let me suspend/resume. I was lucky and got it into working state:

pavel@amd:~$ nmcli dev
DEVICE  TYPE      STATE        CONNECTION
wlan0   wifi      connected    openwireless.org
eth1    ethernet  unavailable  --
lo      loopback  unmanaged    --
pavel@amd:~$ nmcli radio
WIFI-HW  WIFI     WWAN-HW  WWAN
enabled  enabled  enabled  enabled
pavel@amd:~$

Best regards,
