Do not set up multiple APs. Use a real mesh network designed to be used together.

Multiple APs with the same SSID will not only interfere with each other, they will hold on to clients for way longer than they should, meaning as you walk around the house, you’ll have super weak connections, even if you’re close to the next AP.

Mesh networks talk to each other over a lower band to coordinate both interference and clients, so they work way better.

If you must have a specific router, just use it as a router, and set up the mesh router and satellites in AP mode.
