RBK14 Satellite dead zone

1 of my RBK14 satellites when it i connect it to the router it creates a "dead zone" in its range. Without that specific salellite a have an "ok" signal throught my entire house (due to the construction not the mesh system). But 1 of my salellites is hinky. As soon as I connected it to the router that room looses all connectivity! The app shows that satellite connected to the router, but zero connected devices. And if you walk into the room with THAT satellite, its like walking into a Faraday Cage, all connectivity is lost. I paid for the 1 router and 3 satellite system because my home construction is so screwy I need multiple satellites to get a goo/fast connection everywhere in my house. So, I want to be able to use ALL of my satellites!
