unable to enable wifi

[TMG1961]

I have a Realtek RTL8822BE 802.11ac PCLe adapter but i am unable to select wifi because the option is not available when i click on the network icon in the panel.
Wifi works fine on windows 10 but not in Linux Lite

What's the output of

Code:

$ iwconfig

  check network status

Code:

$ sudo systemctl status systemd-networkd

Try restarting network manager

Code:

$ sudo systemctl network-manager restart

I just reinstalled Linux Lite 4.0, updated and then upgraded to 4.2. Now all is working again. Not sure what happened that made the wifi disappear.
I marked the post as solved.

Glad you solved it!
