[RESOLVED] Ethernet of Dell docking station not found

Framework Laptop 13 Linux
#1

I am using AMD Ryzen with Ubuntu 22.04. At work we have a DELL docking station using an USB connector. What works:

  • power
  • two screens
  • USB

Not working:

  • Ethernet

I should get an internet connection via this docking station, but I don’t. No Ethernet adapter appears.

Any idea which driver is missing and/or where to get it?

#2

A search suggests that

Is the Ethernet adapter on the dock, and is supposedly supported according to Linux Hardware

Is it just a case that it doesn’t configure the network interface automatically?

#3

Depending on the kernel version you might be hit by this bug:

#4

No, the interface does not show up at all.

#5

In case anybody is reading this thread: It turned out that the docking station is not (and cannot be) connected to wired Ethernet in the moment, so it cannot work anyways. So I have to use WLAN which works fine.

Sorry for the noise! I was not aware that I was using WLAN also with my old laptop.
