Low Signal/Speed Orbi Pro Satellite SRR60

I have one Orbi Pro router and an Orbi Pro satellite. The router is positioned in the middle of the home and has a very strong signal. The issue I am having is with a satellite that I've positioned on the top floor. When I'm next to the satellite, the signal is very strong/speed great. When I walk less than ten feet away from it- the signal and speed drops to 11% of the speed it was closest to the satellite. There is not a wall or a door impeding the approx 8' space. There is a high pitched ceiling in the area that the signal is weak. Could it be the high pitched ceiling? I would love to use a laptop in that area but it's very splotchy and I'm wondering if there's anything I can do to fix it? Anyone have an idea why this is happening? 

Thanks,

Becky
