Ethernet not detected on Gigabyte Motherboard

I’m not certain what information I need to provide. Can provide whatever is needed to troubleshoot. Checked some other solutions in #help, but not applicable to me.

can you type
lspci | grep Ethernet
lspci | grep Ethernet
and post output I suspect the Ethernet device is not supported By kernel

Just anecodotally, i had a gigabyte motherboard once and it had the weirdest/most difficult ethernet drivers.

if it is this ehternet deivce you have, you will have problems: https://linux-hardware.org/?id=pci:10ec-8125-1458-e000

yeah, this ethernet driver has problems, I have the same one
Archduke Sleepyhead
So it may be the board itself is not support on Linux kernel?

you probably need an out of tree driver and that is difficult to do on bazzite

I just purchased the motherboard, so as annoying as it is, I could take back and get a new one. I only purchased because the specs were about the same as my original plan but it was on sale for 40% off Any recommendations on boards if I need to go this route?

If you're in the return window that feels like a good idea ^

Sadness I’ll pull it out now Any recommendations on boards appreciated. Recommended to reinstall OS after swap?

No need at all And you can always use an external Wi-Fi card, in my case I use a PCIe adapter that lets me plug a laptop wireless card in to my desktop And then I use an Intel AX210, which is probably the best supported hardware in Linux Maybe you're lucky and your board has a swappable Wi-Fi card?

I just took it out, in store looking good for a more reputable mATX now. Hoping to get back up and running today!

New board acquired! Solution. Hardware incompatibility issues with Ethernet support in Linux kernel. Will follow up closure after working system is established. Thank you everyone.

For what it is worth, I got it working in 6.13 kernel

All is working now. The gigabyte board was replaced with an asus. I suppose without some advanced tinkering, gigabyte boards don’t have Linux kernel support for Ethernet

Nah, it is just the realtek wifi/ethernet drivers are a bit behind on driver support in the kernel. It is getting there, but slowly.

As far as I see all the x870/X870E boards are using the Realthek 8125/8126 chips Does the driver for those chips really don't work? That would be kinda tough:bobofrfr:

I have a 2.5G realtek 8125 in my ASRock x670e pro-rs. Works fine never had any problems with that or had to do anything to get it to work 🤷 lspci | grep Ethernet 77:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)

It will probably work in next update Yeah it has been hit or miss for some, but there was a bug on the chips relying on the r8169 module of those drivers. The firmware should build properly in 6.13 kernel.
