House with built in Ethernet ports, half of the ports are not working

They’re 12 ports in this house, my electrician patches all those ports and I’ve bought a 24 Port PoE switch, and connected everything up, but only like half of the RJ45 jacks are working. I’ve connected every patched port from the patch panel with the switch and they’re still not working, some are, some aren’t!

What can it be? It seems like everything’s correct

My router is in the basement, next to the switch and the patch panel

The connection goes Router -> Switch -> Patchpanel -> Wall jack

Thanks in advance
