[SOLVED] No more network drivers after system update

zrchuser · 2018-09-01 17:59:38

I just update my system and after reboot, I can not found both wired and wireless interfaces anymore using

 ip link show

I checked drivers status using

 lspci -v

and there is no line with "Kernel driver in use: .... " for the ethernet controller and network controller. I had no problem with those drivers before.

Please let me know if you have any idea about this issue.

What is the output of `pacman -Q linux` and `uname -a`? Please use code tags not quote tags for commands and their outputs and please show actual command outputs.

zrchuser · 2018-09-01 18:09:12

Ok, difficult for me to show exact command outputs since I can not use the same computer to post messages, the result of

 pacman -Q linux

is

 linux 4.18.5.arch1-1

and the result of

 uname -a

is

 Linux achuser 4.18.3-arch1-1-ARCH # ...

There is a mismatch between the booted kernel and the installed kernel package that supplies the network modules hence the lack of networking.
Most common cause is updating the kernel without /boot being mounted. Downgrade the kernel package to match the modules. Then mount /boot update the kernel package and add /boot to the fstab.

Note the difference? The 4.18.3 kernel cannot find its drivers since they were removed when you updated to 4.18.5.

Mount the boot partition on boot. (I wager it is not)
Reinstall the kernel using pacman -S linux It will used the cached version.
Reboot.

Fix your /etc/fstab so that this does not happen the next time you update the kernel

Edit: Loqs beat me; I like my solution better

I suggested the downgrade as if /boot is fat32 the modules for mounting will not be available.

thanks for your answer, I managed to downgrade the kernel and get an internet connection, I will look on how to configure fstab to add /boot

Is /boot in the systems fstab?

zrchuser · 2018-09-01 19:03:31

nope I forgot to modify fstab, and I am looking on how to do it since I use encryption so I have to edit crypttab too

zrchuser · 2018-09-01 19:06:36

Ok thanks my initial problem is solved, I will look for properly configure fstab to avoid this problem at the next update.

Oh, good point. I still have the mindset that the boot partition is ext.

It leaves me wondering whether we should bake fat32 into the kernel rather than having it as a module.
