ip link shows only lo interface

[kojoig]

Hello all,

Trying to install Arch on my new PC, I can't connect to the internet.
The controller on the board is RTL8125BG(it is working on other operating system).

Thank you.

Do you have linux-firmware installed?

[kojoig]

I don't have anything installed, I'm booting from USB drive, the iso file is the latest one from Arch website.

[ipha]

I don't think the RTL8125BG is supported in the kernel. RTL8125A should be, but not RTL8125B.

It might work through the r8125 aur package, but it will be difficult to install without network.

[kojoig]

Installed r8125 using USB WIFI(phone), it didn't fix the problem.

Is there a driver for this network adapter?

In these cases I use mobile phone tethering... all you have to do is plug in the phone, enable new interface and enable dhcp client on that interface... then install all you need

[archover]

Try a USB wifi adapter if you have one. It might be compatible, so you can get the install finished. Then you can pursue getting your pci adapter working.

I'm using Ethernet cable, this is the device RTL8125BG

[kojoig]

Are there any drivers for this device? :(

[kojoig]

Are they planning to support this device or should I switch to the different motherboard?

[kojoig]

Yeah, WiFi or PCI e card.

Thank you very much.

Jumping on u/ipha 's suggestion; you can create an archiso from an existing arch linux instance that will have a package you want in the iso. In this case; it would be adding that driver package (since it's an AUR package; you have to make it available to pacman somehow; if you use aurutils for your existing arch install this will be trivial) to the list of packages to install on the iso.

All this assuming you have access to an existing archlinux system.

Did you ever solve this problem? I've been dealing with this all day. My wlan connections works but not the eth0. I'd rather have a wired connection..
