Network adapter gone after recent update

I updated yesterday but didn't reboot until I went to bed, and this morning I was greeted by a computer with network not working only loopback listed as a network adapter in ip link show

The actual adapter (Realtek RTL8111/8168/8411) is listed under lspci.

Re: Network adapter gone after recent update

Did you actually reboot into the correct kernel?

uname -a
pacman -Q linux

should match in versions. Other than that check your dmesg on whether there are any issues loading the relevant kernel module.

Re: Network adapter gone after recent update

Yes, it did match. I ended up downgrading it and a bunch of other packages but it didn't make a difference either.

I'll try to check dmesg when I have the time

Did you check if it is correlated to:

Re: Network adapter gone after recent update

It's not related to that. I don't have Windows installed on this PC and ip link just straight-up only displays loopback as the only link.

I'm looking at the dmesg log rn but I don't really know what I'm looking for and I'm not sure I can transfer it to another PC to upload it anywhere atm

Re: Network adapter gone after recent update

Wow I did

sudo modprobe r8169

and it loaded the network driver and it works now but I don't know if I'll have to do it every time I boot now?

Re: Network adapter gone after recent update

Do you have https://archlinux.org/packages/community/x86_64/r8168/ for your kernel?
"uname -a"?

That Realtek NIC card is really faulty. Makes a lot of issues.
Having that card, I have noticed that even without Windows, rebooting the UNIX systems (not every time) might cause the card to be disabled.
I also suggest to use external r8168 driver not the r8169 which sometimes behaves abnormally.
Try to install the driver with Seth suggestion

Thanks. This worked for me, since WOL used to work for me before and then it stopped.
The link to install the r8168 helped in the restoration.
