SUMMARY After Neon "wakes" from suspension, one in two times there is no wifi connection any more. I experienced this on three different machines. It is irritating and leaves a bad impression of Neon. But the solution is in fact very simple! In the file /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf change the line wifi.powersave = 3 to wifi.powersave = 2 After I did this the problem didn't occur any more. And there is no reason for me to doubt Neon! It is a friendly suggestion of a happy user. STEPS TO REPRODUCE 1. startup Neon KDE 2. bring machine in suspension state 3. wake the computer - very often there is no internet connection any more. OBSERVED RESULT No connection to the web EXPECTED RESULT Connection to the web SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: KDE neon 5.17 (available in About System) KDE Plasma Version: 5.17.4 KDE Frameworks Version: 5.65.0 Qt Version: 5.13.2 ADDITIONAL INFORMATION
I received an email concerning this bug. Very cool! I had forgotten it. But I found a way to work around it. I found that when I changed "wifi.powersave = 3" to "wifi.powersave =2" in the file /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf, wifi kept allways working on that system. To achieve this I used sed: sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/g' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf I now have an other machine. That doesn't need this tweak.

Seems like this was ultimately a wifi driver/power management bug.
