Good morning, I recently bought a 3 floor house. In his basement I have set up a recreation room, it has large walls and there is no mobile line or 3g data, so I installed the
fiber optics that goes well 300Mbs. This basement has its own light box. I have the problem to bring the Wi-Fi to the rest of the house because the signal does not reach beyond the basement. I bought the Mesh wifi system with Powerline tplink px50 that brings the internet signal through the electrical line but since the basement and the house have different electrical panels, although they are connected to each other, the system does not work and the mesh network does not reach beyond the basement either .

Any help is greatly appreciated.
