LAN Ethernet is missing

  • I am using the H61H-G11 motherboard. The motherboard has a Controlador Fast Ethernet Realtek 8111E Wake-On-LAN. There is no connection, the LAN controller is not in the system. What is the problem?

Depending on your specific ethernet controller you may need to either install or remove the $kernel-r8168 package were $kernel refers to your current running kernel e.g. linux515.

Hi @Netifer, and welcome!

It would seem that you do not have the drivers for said adapter. But luckily I see it in the repositories as well ass the AUR:

There are for many kernels. You’d have to know for which kernel, to install the driver for your kernel.

Alternatively, AFAIK anyway, you can install the *-dkms version, which might actually be better, because it survives kernel upgrades. The driver is in the AUR, so can be installed with:

pamac build r8168-dkms

Hope this helps!

I’m using kernel 5.15.

The kernel headers aren’t installed. Install them first, using:

pamac install linux515-headers

If NIC driver is installed in mhwd or Manjaro Settings Manager it will install the additional headers files and blacklist the r8169 driver
