Question Speed Problem with 2nd and 3rd Routers

[Woodworker22]

Hello all, this is my first time posting here so please be kind. My newly created network looks like this. Any suggestions on what to look for to fix the speed issue and how to connect to the third router without being in that room?

Try hooking them together via the lan ports. I am assuming these devices have a AP mode and you have set them. In any case make sure the DHCP function is disabled on the 2 slave routers.

It should not make a difference but if you use the lan ports the traffic does not pass through the cpu. The lan ports are acting as a small switch which tends to be much faster than wan/lan traffic.

Still it should give you faster speeds. I would suspect a bad lan cable especially if it does this when you connect them lan-lan.
