Network is not working after update

After updating my system my network devices are not working. Also the system is taking much longer time to boot. I’ve already tried downgrading my network manager but that didn’t solve the issue.

I recently had the same problem, uninstalled the linux56-r8168 package, and added blacklist r8168 in /etc/modprobe.d/blacklist.conf to fix this.

boot on USB iso manjaro live
check ip is on

open a terminal

sudo manjaro-chroot -a ( type 1 if only one line appears )
pacman -Syy ( check ip is on )
mhwd-kernel -i linux54
mhwd-kernel -i linux57
mhwd-kernel -i linux58
exit ( quit chroot )

reboot , and press Esc or Shift to get Grub
and select in details one other kernel

see also switch between r8168 or r8169

That is your problem. Kernel 5.6 is EOL for several weeks and got removed from the repositories. Upgrade to a maintained kernel.

While installing a kernel using mhwd-kernel in chroot I had some errors saying no target specified. So I had to use pacman to install the kernel and headers pacman -S linuxXX linuxXX-headers

Hmmm… I’m probably capturing that thread gnihihi

I’m also running Manjaro on an Acer with a Realtek r8168 network-device. In my case (either on Kernel 5.7 AND on 5.8) I do experience network-drops. After disabling/enabling the network again everything works fine - till a few hours later it down again.
I’ve looked into dmesg, but there’s only my disabling/enabling event and the following “link up” of my driver visible.
