Random connection drops with LAN and Wifi

Hi Manjaro community,

I’m experiencing random internet connection dropouts with LAN and WiFi and am not sure where to start troubleshooting.

My laptop has a Realtek RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet and a Intel Wi-Fi 6 AX200 network device. Wifi is directly coming from my router Speedport Smart 4 (unfortunately bound to that by my provider). Ethernet is connected to the same router via a powerline adapter. I’m running 6.12.43-1-MANJARO with KDE 6.3.6 on Wayland, with Windows 11 in dual boot.

The random dropouts have been happening since a while now and only on Linux and never on Windows. They happen whether I’m connected to Ethernet only, WiFi only, and both in parallel. I cannot yet identify a pattern when they happen or for how long they happen. During a dropout I see in the network popup that the connection is active however download and upload speeds are 0 B/s.

I’ve found some posts that recommended to blacklist r8169 and only use linux612-r8168 as driver, so I’ve done that. Other than that I don’t really know where to start looking for the issue or start troubleshooting. I’m hoping that this information helps an I’m happy to provide more if necessary.

First disable mac randomization and power save. Lots of times one of them or both cause random network disconnections:

Hi @wunst ,

I wonder whether you could read this post, in order to solve the problem.
[Stable Update] 2025-08-29 - Kernels, Toolchain, Virtualbox, Mesa, Wine, ZFS - #42 by philm

Hope it help,

Regards

Resync your mirrors and update, version 6.12.44-2 from today should solve it. (Still testing but i did not see a disconnect so far)

There was a kernel regression, which got fixed lately in linux617. Also all stable kernels were affected. So far we backported it to all branches of Manjaro.

Thanks for the hints. I’ve updated to kernel version 6.12.44-2-MANJARO, deactivated wifi power safe and mac randomization, and will see if the disconnections are fixed.

In case they occur again, is there a better way to see what’s happening other than journalctl --since "2min ago"?

Do you mean:
I won’t see it with this command if the event is more than 2 minutes ago?

You could have a minimized terminal running all the time, displaying the log messages as they occur:
journalctl -f

Sorry that wasn’t clear enough. I wondered if there are any other commands to specifically check for network issues or filter the logs for relevant content? With options journalctl -b0 -x -u NetworkManager I get a lot of information but wouldn’t know what to look for.

Anyhow I haven’t had network issues since I updated to 6.12.44 and made the other changes, so I consider this solved.

Not really - the messages might come from kernel or another facility - and by filtering for just one
like NetworkManager,
you might miss important stuff.

journalctl -f
on an already running system should not produce too many messages and you’d see issues right away.
