MacBook Pro M1 is not detecting Ethernet via USB-C Monitor, any ideas?

Hi there,

I had a similar situation using an Apple USB Ethernet Adapter on a MBP M1. It showed connected status but did not work with the same manual IP configuration used with an older Macbook Pro.

For me this worked (beware that I know my configuration details, so you may need to write down yours beforehand):

1. Remove the non-working network connection in System Preferences > Network using the "-" when selected
2. Adding a new network connection using the "+" for the same interface (Apple USB Ethernet Adapter)
3. Re-adding the connection details

My guess is this has to do with Apple Cloud configuration sharing magic that simply does not map to the correct network interfaces on the new device. But that is just a guess.

I had this problem too... After a while of troubleshooting with Apple Chat and reinstalling my OS nothing worked.

I think I might have a solution though. At least it worked for me.

Go to settings > Select Network

Select the service (in my case "USB 10/100/1000 LAN") > Change Configure IPv4 from "Using DHCP" to "Using DHCP with manual address"

Type a correct IP address and you'll be connected to the internet

I was able to change it back to "Using DHCP" and still keep my connection afterwards, even after reconnecting.

I hope this might help some other people too and maybe help Apple to fix the bug.

Hi to both, I have been having the same issue, with both of my docks not being able to connect to the M1 to provide ethernet. I tried the recommended solution above, it shows it is connected, but when I turn off my wifi (to depend on ethernet), it does not connect to the internet at all.

Has anyone got any solutions?

Just got an M1 MacBook Air and have same issue. Using a USB-C hub with Ethernet. After reboot it wouldn't connect to ethernet. I have to unplug the dongle and plug it back in to get it to redirect.

Hope Apple fix this.

This worked for for with my Anker usb c hub. I did also have to download the drivers for the ethernet port from Anker first which is odd because I never needed drivers before.

Unfortunately that didn't work for me...

I had the same problem, and then I switched the ports, and made sure the cable was all the way in in the usb port. No more DHCP problems and it works now. Maybe that works for some of you...

This worked for me using a j5Create JCD543 triple display docking station. Thank you very much! The ethernet in my office is great and the wifi is terrible.

The upon cases couldn't work for me...

In my case, only can work after I logged out user for a while and then reopen.

Hope Apple face this issue.
