SWAP SATELLITE FROM RBK753 TO RBK752

HELLO EVERYONE.  I HAVE BEEN USING MY RBK752 SINCE JUNE OF 22.  ITS COVERAGE HAS BEEN AMAZING.  I NEEDED ANOTHER SYSTEM FOR ANOTHER BUSINESS.  I PURCHASED A NEW RBK753, THINKING THAT I WOULD NOW HAVE AN EXTRA SATELLITE IF ONE WENT DOWN, OR IF I NEEDED MORE COVERAGE AT ONE PLACE OR THE OTHER.  LONG STORY SHORT, I NEED TO USE THE UNUSED SATELLITE FROM THE 753, ON THE 752. UNFORTUNATELY, I AM HAVING TROUBLE ADDING IT TO MY EXISTING 752 NETWORK. I HAVE RESET IT, AND SYNCED IT TO MY ROUTER. MY NETGEAR APP RECOGNIZES THE ADDITIONAL SATELLITE. IT’S LISTED IN MY NETWORK MAP, AND HAS A GREEN DOT SHOWING ITS ACTIVE AND ONLINE, BUT NONE OF MY DEVICES SHOW TO BE CONNECTED TO IT……ODDER STILL, THE PHONE AND PC I HAVE WIRED DIRECTLY TO THIS SATELLITE DO NOT SHOW TO BE CONNECTED TO IT, NOR DO THEY APPEAR ANYWHERE ON ANY LIST OF DEVICES. BUT THEY FUNCTION PROPERLY.  THE 753 PASSWORD AND WHATEVER ELSE, CAME PREPROGRAMMED IN THAT SATELLITE.  I ASSUMED RESETING THAT SATELLITE,  MADE IT PLAIN AS IF I HAD ARBITRARILY ORDERED AN ADDITIONAL SATELLITE.  WHAT AM I MISSING?  THANK YOU FOR YOUR TIME AND/OR SUGGESTIONS.
