Ethernet port problem tp-link RE650 v2

Hi, The ethernet port does not appear tp-link RE650 v2. I have tried reset to reset the configuration but that didn't solve the problem.

Does anyone know how to fix this error? Thank!

let's see your configuration.

What are you expecting to happen (i.e. is this device serving as a router or an extender or something else)?

Are you able to get a physical link?
How are you resetting the configuration and making changes -- is the ethernet port working for that?
