I got a problem with my network. For simplicity reason I will say Router A and Router B. Router B is connected through a wire with Router A. I ran from the Router A port straight into the WAN Port from Router B and this creates an entirely new network.
Is there a method to make one big network so I can access devices that are connected at Router A through Router B or should I make a routing table so Router A knows the other network?
edit: For example I want to stream something to a TV that's connected with Router A and my device is connected to Router B
