Hi
I bought a flat from the developer. I have 3 ethernet sockets in the apartment and outside the apartment - in the staircase - I have a teletechnical box in which there are 5 ethernet sockets, fiber optics, concentrators for TV / SAT. I would like to make a LAN in the flat and I have a problem how to do it.
Is it normal to install the router in a staircase so that I have a network in every outlet in the apartment? I do not know what the practices are because I encountered something like this for the first time.
Is it better not to give anything to this box and instead establish a point in the apartment, which will be the focal point, release WAN from it to the box and then put the router in the apartment at this point and pull cables to all rooms from it?
