Ethernet adapter not working after switching kernel

Hey there, as the name suggests, I have a network issue.
EndevaourOS kept crashing on the regular kernel, and a guide here suggests switching the kernel to the LTS one. So I did.
As soon as I launched my browser, I was met with the “no internet” screen.
The WiFi was working, so I was at least connected to my network that way.
What do I do?

machine specs:
CPU: Intel Xeon E5-2630L v3 x16 @ 2.900GHz
GPU: Zotac/Nvidia GTX 750 Ti
Kernel: 5.15.32-1-lts
MB: Machinist X99-K9 (Chinese-brand motherboard my dad got me from AliExpress)

It is hard to say without seeing any hardware info but if I was guessing, I would say you need to install the network module matching the LTS kernel. When this happens it is often that r8168-lts needs to be installed. If that doesn’t work, we will need some more information to help you.

erm, did you check what I wrote at the end? but thanks, I’ll try it now.

Are you referring to this?

If so, we need much more detail than that.

inxi -Fxxxz would be a good start if that doesn’t work.


ah. here’s everything under the network section:

Device-1: Intel Wireless-AC 9260 driver: iwlwifi v: kernel pcie: speed: 5 GT/s lanes: 1 bus-ID: 05:00.0 chip-ID: 8086:2526 class-ID: 0280
IF: wlan0 state: up mac: <filter>
Device-2: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet
driver: N/A pcie: speed: 2.5 GT/s lanes: 1 port: d000 bus-ID: 06:00.0 chip-ID: 10ec:8168 class-ID: 0200

also, adding to this, I installed the r8168-lts thingy. what now?

That should be all you need. Restart the network or just reboot.
