WiFi randomly disconnects and shows 'No Networks Available'

[Arrababiski]

If you are experiencing wifi disconnections, I recommend first these two workarounds:

1º Disable wifi power saving
2º Disable MAC randomization

RTL8822CE Instability even with newest kernel

You can try two workarounds. Turn off wifi power save first. Create .conf file: sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf And copy these two lines inside it: [connection] wifi.powersave = 2 If the issue remains, turn off Mac Randomization. Create .conf file: sudo nano /etc/NetworkManager/conf.d/disable-random-mac.conf Copy these two lines inside: [device] wifi.scan-rand-mac-address=no Hope this can solve your problem.
