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

FWIW, I have been using a Belkin Multimedia USB-C Hub from the first

day I have my M1 MacBook Air (last week of November 2020) and the

ethernet has functioned flawlessly from day 1. That has been with

Big Sur 11.0 through 11.2.

If it shows the "green" connected light in network preferences, select the

advanced setting an under TCP/IP click "Renew DHCP lease".

The other possibility, delete the ethernet interface in Network preferences

and then re-add it. Sometimes config files simply get messed up.
