The Ethernet Card of my Apple MacBookPro10,1 is a "NetXtreme BCM57786 Gigabit Ethernet PCIe". It is not working any more since I have installed elementaryOS 6.1. With elementaryOs 5.1 it had worked seemlessly.

I've done a hardware probe and it says: "Driver is not found or not configured. We have not found a driver for the device in any Linux kernel versions up to 5.19 (according to the LKDDb) or known additional packages."

So it seems, there has never been a dedicated linux driver for this particular ethernet card, but it has been working with another (default?) driver.

Is there a way to pick the ethernet driver of elementaryOS 5.1 and install it on 6.1?

The comment of @Vlad helped me get on the track. As discussed here in brazilian Portuguese, I had to:

  • In Terminal, type
    • sudo apt-get update
    • sudo apt-get install firmware-b43-installer
  • restart

Note that according to this answer and Vlad's comment, I first did:

  • In Terminal, type
    • sudo apt install linux-firmware linux-modules-$(uname -r)
    • sudo modprobe -v bnx2x
  • restart

... but I don't think it is necessary here, as the latter installs the drivers for the model "BCM57810", not "BCM57786".
