Orbi wifi 6 RBK753s-100NAS satellite AP mode woes

As I powered on the router connected behind FIOS Quantun gateway, it switched itself to 10.x.x.x network to avoid conflict with Quantum IP address range. I then paired the satellites which got 10.x.x.x addresses as well. Then I switched the router to AP mode and had created a static reservation for the RBR on Quantum gateway, which got its reserved IP. However, the satellites never connected back despite trying exactly what you said. Pressed the sync button on RBS and the tried both ways on screen button (add satellite option) or on the back of the router sync button, but it kept on failing. Then I connected the RBS to the lan ports on the RBR (one at a time) and then I was able to sync. I was hoping now I could remove the network cable and it would stay sync, but it did not connect in wirelees mode.

Anyways, I might try once more, otherwise may be i have bad router/satellite hardware and they are going back unfortunately.

The process is not rocket science, I am upgrading them from RBK53 (the non AX older version of Orbi mesh) and the process was relatively straigth forward.

Thanks
