Herelink v1.1 Ethernet Problem

Hello all,

I have an issue with the Ethernet in Herelink V1.1.
details: When I plug in the ethernet port into my laptop, I don’t see the ethernet port in my PC have led light.
Also, I have done some Ping commands from my laptop to the receiver here link but did not get a response.
Any idea to help me resolve this problem?
Thanks!
