[SOLVED] Wired connection keeps resetting
Almost every second, the KDE Plasma Network Manager notifies me that Wired connection 1 deactivated; then Wired connection 1 activated.
The symptom I will see on web pages is:
Your connection was interrupted
A network change was detected.

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
35 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.Last edited by mparillo (2021-04-01 01:33:08)

Thank you. I assume that means I should systemctl disable one or more of the above?
Short of randomly trying each possible subset, which would be most promising?
I would like to debug my wireless next, so I will need wpa_supplicant.service then, right but I can disable it for now.
And I need dhcpcd.service because I do not have a static IP address, right?
That leaves NetworkManager.service and systemd-networkd.service. I thought KDE Plasma (https://wiki.archlinux.org/index.php/Ne … KDE_Plasma) uses Network Manager and systemd must use networkd.

Re: [SOLVED] Wired connection keeps resetting
You disable them all. Then you read the wiki page on the manager you want to use, and follow the instructions there.
