Description radimir.cacic09 2020-05-10 16:57:53 UTC
The title pretty much sums the issue.
I have Kubuntu 20.04 LTS on my laptop and this WiFi applet is driving me nuts.
It just randomly disconnects you from WiFi, takes a few minutes and then reconnects you.


SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.18.4
KDE Frameworks Version: 5.68.0
Qt Version: 5.12.8

Are you sure it is an KDE Plasma issue? This applet is just an interface for underlying Network Manager service.
It looks more like an issue with WiFi driver, or WiFi network, or Network Manager or hardware...

You can disable Network applet by:
* right click on the small arrow in the system tray (usually between icons and clock)
* select System Tray setting
* disable Networks applet

Then you can connect to WiFi network using command line tool:
nmtui
or
nmcli

In additional, can you check if problem occurs on Ubuntu 20.04?

Hi Konrad. Thank you very much for your reply.
I think this should be KDE Plasma issue because I've been using Plasma for ~2 years and this is the first time I've encountered this. (it is the same laptop for 2 years)

The problem does not occur on "normal" Gnome Ubuntu 20.04, only on Kubuntu 20.04.

Thank you.

This is definitely not a plasma-nm issue. It is most likely a driver or NetworkManager issue. There also hasn't been any change recently that could cause such behavior.

Can you report your issue to NetworkManager instead?
