Satellite recommendation

[Supermansings]

I have the setup with router, 1 satellite indoor and the outdoor addition. Still missing coverage just in master bedroom. Does adding a wall plug in drop back haul speed for all or do I have to get another 200 dollar satellite to maintain speed?

You are not likely to noice any difference in performance.  The hard part is finding an Orbi satellite of any model.

What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended or more 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
