[Unitree GO1] Unable to use internet on Go1 Nano 15

I already tried using this for head nano (.13) which worked fine initially but then the eth0 automatically went down.

Please connect a LAN cable that has an internet connection to the go1, and then run:

sudo ip link set eth0 down && sudo ip link set eth0 up
sudo dhclient eth0

Then you can check if the internet is active via:

sudo apt update

But this did not even work single time for Nano 15. Can you please tell me how to do that?
Because I am using Nano for navigation.

This wiould require more comlex networking to enable internet. Currently, we do not have our GO1 test unit on hand so you may have to check online on how to share internet between connected pcs or perhaps some other user can assist.
