So, before explaining this is the situation drawn out:
------- Router_1
|
Modem --- Router_2
|
------- Router_3
Three routers on 3 seperate floors of the building all connected to the modem (lan-cables through the walls attached to the modem). So that means 3 access points on each floor and there is no way to connect the routers to each other. Every time you go to a different floor of the building you manually change your access point on your device, i.e. phone, laptop, etc…
How do I, or can I even do it, create a “single access point” like in a Wifi-Mesh where it switches automatically to the stronges signal, without needing to manually switch between routers.
