Hello there, I have problems with my connection using Manjaro KDE. And it’s super annyoing.
I’m currently using network-8169 even though it keeps disconnecting every time I put my computer on sleep. When I boot up my computer I have to wait ~1 minutes before it connects correctly to my network. I tried using network-8168 but with no luck: boot time becomes extremely long (2 minutes) and sometimes my computer freezes repeatedly making it unusable.
Also I use r8169 and I have troubles with connection with Wide 40Mhz channels. If you could modify your router settings to use only Full 20Mhz channel widths you might have a better chance. (Speaking only with my experience resulting from similar simptomps you have).
You can also proceed with pinpointing of the problem by trying kernel 5.9 or the older LTS if it has the same troubles.
No luck. I tried using r8168, disabling ipv6, even reset my modem router, but the problem is still there.
What drives me mad is that my moteherboard is widely used in the world, and manjaro (and linux in general) can’t figure out how to handle it. It’s like 1997 again.
Do you have a custom DNS? if so try to have full auto configuration for a test, reboot and see if it connects instantly on boot with the r8168 installed from the System Settings.
PS: I have similar hardware (B450M DS3H), and at some point the r8168 wasn’t installed anymore, not sure how/why, it took me time to figure that out, I reinstalled the driver from System Settings -> Hardware and rebooted, still same behavior, then I reset all configs in Network Manager, full auto, rebooted, works perfectly.
Yeah, I’ve installed it via GUI on Plasma settings. It automatically puts network-8169 in blacklist.
This is my log:

Just booted my computer, it seems everything works fine.
Yeah I already tried to reboot several times, although after installing network-r8168 and using defualt network settings everything seems to work just fine. I will tell you guys if there’s any other problems.
What really bothers me is the inability of using custom DNS.
Hum… OK… I just see your log file starts 5 days ago but OK I specifically wrote you needed to reboot for changes to properly take effect.
Yep, this is the only problem I don’t know why yet, for now I use the setting in Firefox to have custom DNS in web browser (General Settings → scroll to bottom → Network Settings → scroll to bottom → Enable DNS over HTTPS → select CloudFlare or whatever).
