Macbook Air M1 2020 not recognising ethernet cable

I am unable to connect my MacBook Air to the internet using ethernet connection, I was able to do this on my intel model, but not this new M1 model. it is the same two hubs which worked on my old MacBook but not this one. I have tried to configure the IPv4 using DHCP with Manual Address, and Manually, they show 'connected' on the left hand tab, but it still doesn't let me connect to the internet.

Any ideas? Is this an hardware issue, or Big Sur?

Anyone else having this issue?

MacBook Air 13″, macOS 11.0

Hello,

I solved my issue with the ugreen type C ethernet 1gbits adapter.

Turns out the issue wasn't the M1 but big sur lack of driver.

Check if your device has the following ethernet chipset : AX88179

If yes, download the driver here :

https://www.asix.com.tw/en/product/USBEthernet/Super-Speed_USB_Ethernet/AX88179

And follow the installation process provided with the .txt file:

"This is a beta driver.

The following steps are necessary to enable Develop mode.

1. Disable SIP in Recovery mode then reboot.

2. Enable System extension develop mode. Open the Terminal and issue the following command.

$ systemextensionsctl developer on"

I posted the Ethernet problem back on 29th December, shortly after receiving my new MacBook Air M1. I've now updated the OS to Big Sur 11.2 and this bug has not been resolved or sorted..... very poor show by Apple... with only two USB-C ports we all have to connect some sort of hub for USB-A, HDMI or indeed ethernet direct connection to my fibre to get maximum broadband speed..... APPLE PLEASE SORT THIS OUT, surely you are listening to the issues from your customers... or at least advise that a fix will be on the way..... just relying saying try starting up in safe mode is not acceptable and we are not all IT wizards and able to configure any fancy workarounds or interim solutions..... meantime it is back to WIFI only for me.... ehhhhh...
