Ethernet connection not working Qubes 4.1 Lenovo X230

Wifi works. When disconnect wifi and plug in ethernet cable, no internet connection. The GUI in top right corner says Ethernet Network (Intel 82579LM) - disconnected. It works fine on another laptop.

This used to work, and I believe it stopped working after upgrading Qubes to 4.1

What is the best way to debug this? Can I see some logs?

All the logs available in a normal install are available after boot,
(but not persistent to the next boot.)
Qubes specifics logs are also available from Manager->qube->Right click->Logs

I never presume to speak for the Qubes team. When I comment in the Forum or in the mailing lists I speak for myself.

Ok, I guess I’m asking how to check logs for ethernet connection. I can open terminal in sys-net (the vm that has ethernet device attached) and check those logs. Which ones?
