Can existing multiple routers be converted into a mesh network? I have a 3-floor building where the ethernet wire runs on each room of every floor. All wires are connected to a switch which is then connected to the main router. I don't face any problem when surfing the internet, as I am getting consistently equal speed in all my router(i have connected the wire coming from switch on wan port of the router and set dynamic IP as the internet option), but the only purpose I made my entire building wifi was to access my network resources spread across the floors. For eg. I have a wireless printer that I can access only when I am connected with the same router from which my printer is connected. The same way I have NVR's, Smart TVs, etc.
