Have you tried to replace the ethernet cable with a known working ethernet cable?
If not try to replace it first if not working try to check the ethernet socket and try to clean it with brush and thinner(Laquer flo) then check it again.

If it doesn't work try to reset the miner then also reset the modem then put the ethernet cable to another socket on the modem and then test it again.
If it still doesn't work try to use a router let see if it won't work and then update here.

This seems like a control board went bad, I am afraid there isn't much that can be done about it.

If it has an Ip-report button you should try it, also if there is a way to Sdflash it that might fix it, meanwhile look for a spare control board, you can buy a used one for cheap.

Look at the control board. It's full of dust...

Try the mikeywith suggestion first, and then if the issue persists, do this below.

Clean the control board, then check the parts near the ethernet socket and, maybe there are some parts with rust and corrosion clean them with thinner. If it can't remove, try to resolder them. Use a multimeter to check the ethernet terminal and maybe it's shorted. If you have Hotair(BGA) you can replace the ethernet socket with the new one.

Also, try to make a crossover cable and use it as your ethernet cable.

If all of them don't work, your final solution is to replace it with a working control board.
