orbi wifi 6 RBR750

[juju70]

Why can't i get the satellites to connect.  One connects and the other will not.  The wifi also shows as unsecured on the iphones.  I am at the point of taking apart and returning because this is just not worth the hassle.

What Firmware version is currently loaded? Be sure the RBS are loaded with same version of FW as the RBR.

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Is the Orbi system operating in Router or AP mode?

What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router
