so we have this problem that whenever we use the LAN cables that the wifi in the entire house goes down, we use 3 routers one in the main room to connect to the wall, the other in the living room for the TV and HIFI and one in my room to connect the PC's, we think its the 2nd or 3rd router thats clashing with one another and that causes the wifi to stop working, the wifi works fine when we turn off the 2nd and 3rd router, is there any solution to this? a way to keep using 3 routers and keep the wifi enabled?
