NetworkManager is not connecting to wifi automatically at boot.

Hi

After logging in to Gnome, the wifi is not established itself. Then I tried the following

>> iwlist wlp0s26f7u1 scan
wlp0s26f7u1  No scan results



>> iwconfig
lo        no wireless extensions.

wlp0s26f7u1  unassociated  Nickname:"<WIFI@REALTEK>"
          Mode:Managed  Frequency=2.412 GHz  Access Point: Not-Associated   
          Sensitivity:0/0  
          Retry:off   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

enp2s0    no wireless extensions.




>> nmcli dev status
DEVICE       TYPE      STATE         CONNECTION 
wlp0s26f7u1  wifi      disconnected  --         
enp2s0       ethernet  unavailable   --         
lo           loopback  unmanaged     --         




>> nmcli dev wifi list
*  SSID  MODE  CHAN  RATE  SIGNAL  BARS  SECURITY 



>> nmcli radio wifi   
enabled

Note that I can't even scan the list of wifi network iwlist command.

Eventually, I have to make the connection explicitly.
That also fixed the scanning problem.

>> nmcli conn up dccy 
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/0)


>> iwlist wlp0s26f7u1 scan
wlp0s26f7u1  Scan completed :
          Cell 01 - Address: D8:5D:4C:F7:15:C8
                    ESSID:"dccy"
                    Protocol:IEEE 802.11bg
......
...

Question is I don't have to do that in the past. What when wrong in the recent upgrade ?
