Re: [SOLVED] enp1s0 doesn't exist

I loaded r8169 kernel module on boot, yet the link doesnt exists.
When I try this I still get an error:

$ sudo ip link set dev enp1s0 up && sudo dhcpcd enp1s0
Cannot find device "enp1s0"

Did you disable "predictable network interface names" so kernel names like eth0 & wlan1 are used ?

Installing iwd implicitly disables this nonsense, but only for wifi NICs (because it doesn't work w/ iwd…)
But we're lacking any wired NIC here

Re: [SOLVED] enp1s0 doesn't exist

Hmm.
I manually loaded `r8169` using `sudo modprobe r8169`, and then when I use the command `$ sudo ip link set dev enp1s0 up && sudo dhcpcd enp1s0`, the link opens up and I get a connection from my ethernet.

$ sudo modprobe r8169

Re: [SOLVED] enp1s0 doesn't exist

For context, I hadn't been using my ethernet cable for around three months. But then I recently plugged it in a few days ago, but it didn't seem to be working with my Linux desktop even though it was working fine on my Windows laptop. So some blog on the internet suggested that I load the module first, then see if it comes up. And it did. So I put r8189 in /etc/default/grub and regenerated the grub config. But that doesn't work. I have to manually load the module using modprobe.

I am using the linux-zen kernel btw.

Re: [SOLVED] enp1s0 doesn't exist

Check/post dmesg. Safe assumption you installed a variant of r8168 from the repos which will blacklist r8169 but are now running a kernel that's either never been built with/for that module or is incompatible with it. Check that remove r8168 if installed.

dmesg:

$ pacman -Qnq | grep r8168
r8168

Your assumption was correct. I will remove it and restart.
