Network issue with 6.4

Support Network
1

Hi.
Strange issue this morning, my network was ok until about 11 AM when I went out, coming back about 1 hour later.
There, no network anymore.
I also couldn’t use my android shared connection.
eno1 & wlo1 desperately down the former was using 8169
This until I rebooted on the 6.1 kernel.

There I did this

And network is back on 6.4

The odd thing is that I was totally up to date and did no update today…

What may have happened ?

I think it’s probably a kernel bug. Over at the PCLinuxOS forum, several people are also reporting the loss of network functionality — mainly Ethernet, but sometimes WiFi as well — with the Realtek RTL8111/8168/8411 chipset in combination with a 6.4 kernel, although in one instance it was also with 6.1, and in that person’s case, switching from the r8169 driver to the r8168 driver only made things worse.

I myself am using the 6.1 kernel with the in-kernel r8169 driver — my chipset may be slightly different though, because this is a desktop, and it doesn’t have WiFi — although until recently I was using the out-of-tree r8168 driver module due to that one having been the default when I installed Manjaro back in 2019. And I can’t say that I’ve ever had any connection problems with either driver so far.

So it may be specific to that particular chipset, and then one can only hope that the kernel developers will hear about the problem and that they get to fix the driver. :thinking:

Thank you for caring.
What is supposed to be the most efficient driver for these ?

Well, the r8169 driver is the in-tree driver, meaning that it’s the official driver as it ships from the kernel developers at kernel.org, but when I myself installed Manjaro back in April 2019, it defaulted to using the r8168 driver, which was no longer part of the official kernel sources — and r8169 was blacklisted in /etc/modprobe.d/blacklist.conf. At present time, Manjaro does not install r8168 by default anymore.

I asked @philm about why Manjaro defaulted to r8168 instead of r8169, and he said that many people were having compatibility problems with r8169 — even back then.

Well, all I can say is that on my system here, I’ve taken the leap and removed r8168, deleted /etc/blacklist.conf, and that I’m happily running r8169 now without any problems. But like I said, I’m on the 6.1 LTS kernel, and my chipset may be slightly different because it doesn’t have any WiFi functionality, given that this is a desktop computer.

So I guess the most efficient driver is the one that works for you, given that lots of people are reporting problems with either driver, depending on their exact setup. :man_shrugging:

:point_up:
kernel 6.4 has really flaws with the realtek chipsets. the network shuts down and is no longer responding as it would disappeared in nothing. fun fact, i connected a usb-network-dongle and switched the ethernet-cable to this and suddenly both (!!!) network adapters are connecting back to the router and the realtek-network adapter is working again. silly game

By the way, I’ve just checked with inxi, and my network chipset is the same as yours. But as I said, I’m running the 6.1 LTS kernel here — I prefer stability. :stuck_out_tongue:

i compiled the clear-linux-kernel-6.4.10 just for fun and the problem is solved. maybe a problem of the shipped binary of kernel 6.4. who knows, who cares ? there’s no reason to think about because kernel 6.5 is coming soon.
