Ethernet device not detected

ikidy · 2026-03-31 22:27:35

Hey all!

I'm unable to use ethernet on my laptop, as it's not detected through lspci/lsusb. I'm using NetworkManager with iwd backend on an Asus ROG Strix Scar 15 G533ZW. Here are things I've tried so far:

- Check nmcli (No ethernet device shown)
- Check ip link (No ethernet device shown)
- Check lspci | grep -i ethernet (Nothing returned)
- Install r8125-dkms, modprobe, and restart nm
- Install linux-zen
- Install asusctl and enable asusd
- Add pci=realloc acpi_osi=! acpi_osi=\"Windows 2020\" to grub config
- Disable armoury crate control interface support in BIOS
- Update BIOS
- Boot into a live fedora environment (Ethernet still doesn't work)

As far as I can tell, no damage has been done to the ethernet port. Asus says my laptop supports ethernet with the provided rj45 port, and I have a cat 8 cable plugged in. Any ideas? Thanks in advance for any help.

if lspci nor lsusb show anything you can stop all attempts at fixing this at the OS level. Check your BIOS/UEFI whether there's a setting that hard disables the card. Alternatively if there are errors in enumerating the device it might show up in the journal in which case you should post

sudo journalctl -b | curl -F 'file=@-' https://0x0.st

the result you get from this (assuming you at least have working internet via wlan)

lspci -knn
lsusb

Please no grepping, there's absolutely no guarantee your vendor would show "ethernet" anywhere

lspci -knnd ::02xx

is more likely to provide meaningful (limited), output but we'll look at all of it.

Asus BIOS settings are very limited. All I could find was "armoury crate control interface support" which I disabled.

0x0.st seems to be down due to AI spam. Is there somewhere else I could upload logs to?

wlan0 works, it's just ethernet that doesn't.

According to this website (which shows a different ram/storage configuration of the same model laptop) I should have a Realtek RTL8125 ethernet controller, which doesn't show up. Maybe this is a red herring?

seth · 2026-03-31 23:14:25

sudo journalctl -b | nc termbin.com 9999

There's no RTL8125 chip nor anything else resembling a wired NIC nor an unaccounted device
Does it show up/can you configure it in the UEFI settings?

ikidy · 2026-03-31 23:34:32

Here's my termbin link:
https://termbin.com/9orn

For whatever reason, Asus doesn't give much control in the UEFI menu. All I could find was a setting called "armoury crate control interface support" which I disabled, and "Network stack" which I enabled. Neither of them seemed to make any difference.

There's something™ wrong on that bus - *might* be the ethernet.

Is the BIOS from last october the latest one available for your system?

"rd.driver.pre=vfio-pci … pci=realloc acpi_osi=! "acpi_osi=Windows 2020" intel_iommu=off" are already mitigational efforts?
Please remove those and post an updated "clean" boot.

* Do your UEFI settings allow you to toggle ReBAR?
* If there's a rj45 cable plugged in on both ends and your board has power (it does when the system is running ), are there any lights flashing at the plug to your computer?

As far as I can tell, yes. It's the latest bios version listed on their website.

I removed these and the same messages still show. Here's the logs:

Not as far as I can tell. There's not much I can do in UEFI.

The port on my laptop doesn't have a light, but the port on the splitter it's plugged in to does, and it flashes, though I don't get any connection from it.

https://wiki.archlinux.org/title/ASUS_ROG_G533QS has a

10ec:8168  Realtek Semiconductor Co., Ltd.  RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet Controller

so this fits, but the PCI errors remain and the device is nowhere to be seen, sanity check

Apr 01 12:22:01 archlinux kernel:  nvme1n1: p1 p3 p4

is there a parallel windows installation?
Any parallel OS? Does the NIC show up there? Does on a live boot of https://grml.org/ ?

In case there's a parallel windows see the 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

ikidy · Today 00:27:03

I don't have any other OSes installed. No other live medium sees my ethernet port. I assume something's just wrong with the port. I've gone ahead and gotten an ethernet to usb c adapter, which works perfectly. Thank you for the help you've given me, even if I wasn't able to get my ethernet port to work.

seth · Today 07:46:48

Can you remove some optional PCI device (eg. the GPU or one of the nvme's) - if you're removing the GPU, don't forget to re-attach your monitor to the IGP
Have you contacted asus about this?
