1. You can check and change the mains module
First you have to try it because it does not make much sense to intervene directly with the motherboard.
2. Check the network antenna, replace it if it is removed and replace it if it is worn or crushed.
3. You have to remove the part on the mains antenna and remove the way.
4. intervene with the power supply to the mains supply, replace it if it still does not supply power.
