Herelink ethernet port not working

hello i have a question about the ethernet port of my herelink is not working although i think the wifi is working as iam able to get the camera rtsp feed to my laptop when i connected the camera to the herelink through hdmi does anyone know what i can do about this or whom i could contact about this issue?

If you want to use wifi you can share an hotspot with your phone, it needs to be 5GHZ. Never tried ethernet sorry,

the problem i have is connecting the laptop on the ground to a onboard computer on the drone side, the problem is used to connect the ethernet port of the airunit directly to the onboard computer now that the airunit ethernet is not working i dont know what to do
