I got an USB 3.0 type C ethernet adapter to my lenovo P1 Gen4, but the network adapter doesn’t properly starts.

I use fedora 36 kde spin, all packages updated, kernel 5.19.11-200.fc36.x86_64

when I plug the adapter to an usb type c port it shows the logs

Early on there was a bug trying to load the module,

(unnamed net_device) (uninitialized): Failed to write reg index 0x0002: -32

It was fixed by setting the following into /etc/modprobe.d/ax88179.conf

softdep ax88179_178a pre: cdc_mbim

Do you see the cause of the problem ?

Please post the output if ip addr, lsusb, and inxi -SNzxx.

In the output shown above I see no mention of connection with IPv4, which may be the issue.

The wired connection had a “virtual mac address” randomly generated set in Network Manager GUI (I can’t remember why I had set that before), so disabling this configuration the wired connection started ok and is at full speed.
