Nothing to do with dhcp here. Reassigning to proper component

Can you please do the following (as root user): - edit /etc/NetworkManager/NetworkManager.conf and set level=TRACE in the [logging] section - set "RateLimitIntervalSec=0" in /etc/systemd/journald.conf - reboot - wait that the problem happens again - attach the output of 'journalctl -u NetworkManager -b' to this bugzilla After attaching the journal log, you could change the DHCP plugin used by NM to solve your issue. To do this, set 'dhcp=dhclient' or 'dhcp=systemd' in the [main] section of /etc/NetworkManager/NetworkManager.conf. Then restart NM with 'systemctl restart NetworkManager'. Thank you!
Created attachment 1682736 [details] screenshot 3 with asked settings right after this error
(In reply to animuspexus from comment #6) > Created attachment 1682736 [details] > screenshot 3 > > with asked settings right after this error Unfortunately the log doesn't fit in one screen. Could you instead do: journalctl -u NetworkManager -b > log.txt and attach the log.txt file? If you didn't reboot since then, you don't need to perform again the previous steps.
Created attachment 1682762 [details] adding complete log file I didn't rebooted. changed to dhcp=system after uploaded last screenshot (this helped). complete log, includingly screenshoted timings, is in attachment.
