Self-assigned IP Address (2022) Macbook Pro 14 inch

Hello,

I have read numerous threads and tried almost all the solutions that I can find on the internet.

My situation:

1) I'm trying to connect to my local ethernet at my office

2) I have a Macbook Pro 14 inch (2021) since March 2022

3) Previously I used Macbook Air 2017, with the latest OSX, using a USB-A to ethernet adaptor, connected to the local ethernet at my office and it worked fine

4) Since I have changed to the MBP 14, I keep getting the "self-assigned IP address" on my MBP

5) I have tried all the solutions that I could fine on the internet

6) I have bought three different USB-C to Ethernet Adaptor: one from AUKEY, one from TP-LINK and the latest one from an Apple Store (the Belkin USB-C to ethernet adaptor).

7) The LAN cable works fine. I've connected it to my Windows desktop and also my older Macbook Air.

I am not sure on what to do now. Does anyone have a similar issue and have solved this?

Thank you in advance.
