Description przemyslawadamek 2018-09-12 03:11:46 UTC

NetworkManager is not able to connect to password protected network after the NetworkManager.service is restarted (`service NetworkManager restart` or restart on failure).

Here is how it looks from the point of view of the user.
https://youtu.be/FlJIuNFkiYY - there is no prompt to unlock kdewallet either.

Workaround:
go to background services and restart "Plasma Networkmanagement module" - https://imgur.com/lbq5n8f

relevant `journalctl -u NetworkManager.service` log:

Tested on openSUSE Tumbleweed.

Comment 1 Zhang Jingqiang 2018-11-08 07:41:31 UTC

Same here with Debian Sid.
network-manager version is 1.14.4
plasma-nm version 5.13.5

It seems plasma-nm doesn't try to reconnect to network-manager.
After restart network-manager, the ssid listed in plasma-nm is marked as nerver-used, which is obviously not correct.
And if I use `nmcli agent secret` to supply the secret needed by NM, then NM can reconnect, but status in plasma-nm won't change.

Comment 2 Jan Grulich 2018-11-08 08:25:05 UTC

This should be fixed in networkmanager-qt with version 5.53.
