XR700: devices disconnect after installed smart light switches

Okay I think I figured it out. I changed to guest network and it did not work. The light switches are connecting all at the same time and I mean exactly at the sametime. So I hit the breaker for all the light switches and noticed everything connected. I waited 1 to 2 minutes to let everything connect. After that I turned on the breaker for the switches and they connected and everything else stayed connected. So i restarted the router and noticed it happened again so i repeated the process and it worked. So i think the router has an issue with too many devices connecting at the exact moment which these light switches are probably retrying to connect at the exact moment over and over. My light switches are iotty smart light switches.
