STEPS TO REPRODUCE 1. upgrade networkmanager to 1.42.0 and/or kde plasma to 5.27.1 versions 2. open kde NM tray applet OBSERVED RESULT Primary Nameserver is not valid (in my case 8.116.124.209) EXPECTED RESULT Primary Nameserver must be valid as in IP4.DNS[1] value from nmlci (in my case 192.168.1.1) SOFTWARE/OS VERSIONS Linux: archlinux with 6.1.12 kernel KDE Plasma Version: 5.27.1 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 NetworkManager: 1.42.0 ADDITIONAL INFORMATION https://bbs.archlinux.org/viewtopic.php?id=283573
Seeing this as well with the same software versions as qtm4ig@gmail.com except Networkmanager updated to 1.42.2-1 today with the same result. Also noticed the IP displayed in IPv4 Primary Nameserver changes with every reboot. Mine is displaying 40.211.92.136 (Eli Lilly in Germany), however I've also seen IPs from the USPS and various other organizations.
Created attachment 156653 [details] NetworkManager 1.42 I have been experiencing the same issue with openSUSE Tumbleweed, KDE Plasma 5.27.1 and NM 1.42 (see attachment). > nmcli connection show wifi | grep -i ip4.dns IP4.DNS[1]: 192.168.0.1 gives the correct nameserver, consistent with /etc/resolv.conf. Restart of NM changes the primary nameserver again. It is not clear to me whether plasma-nm5 or NM is the culprit here. Any idea?
Definitely a Networkmanager bug. Please report upstream. Thanks!
JFYI: The issue is solved for me with NM 1.42.4.
