No network after update/reboot

[spearhead83]

Hey there,

I just installed the latest updates via GUI and after the mandatory reboot I have no internet connection anymore.
I connected via ethernet through a repeater and the repeater via ethernet to the router. The router-GUI says I’m still connected but Manjaro says otherwise.
Since I’m typing on my phone now I can provide the output from inxi -Fazy only as pictures.

Welcome to the forum!

You have a Realtek RTL8111/8168/8411 adapter. Manjaro uses the out-of-tree r8168 driver module from Realtek for that by default, but this driver is now causing problems with the latest kernel updates, and one only needs this driver if one has very old hardware. On any hardware newer than 4 years old with this chipset, it is better to use the in-kernel r8169 driver.

Open up the Manjaro Settings Manager and uninstall the r8168 driver. Then, check whether there is a blacklist file for r8169 under /etc/modprobe.d/— removing r8168 should normally also remove the blacklist file, but if it doesn’t, then just remove it by hand.

Then reboot, and it will automatically load the r8169 driver.

Well, not really ok …

• System up to date with previous update (23-09-10): no problem
• Apply last update (23-09-18) : no network after reboot
• Timeshift, system ok after reboot (so system with 23-09-10 update)
• Remove r8168 driver, reboot : ok with network
• Apply last update (23-09-18), reboot : no network again !
• Timeshift again, reboot : ok with network (so system with 23-09-10 update)

I must add that I still use 5.10 (and 5.4) kernel, due to some problems with 5.15 and 6.1. (long boot time due to unexpected fsck)

We’re working on it…

Thanks for the hint, it did the trick for me on my Lenovo ThinkPad Edge E351 even without a reboot.
