I installed the 5G Gateway box upstairs and get a pretty strong signal. Downstairs is a different story. Not strong at all. I previously used Orbi system with my Spectrum internet. Can I connect the Verizon 5G box to my Orbi? Or do I need to get a Verizon 5G extender? Can I place the Verizon extender downstairs to get a better signal? I was reading that it might not work on a different floor. Thank you.
