RBK50 - Slow Wifi Upload speed

Here it is again, the link works, I tried it, not sure why you can't see it.

But here it is again. 

I seem to be getting slow wireless Internet connection speed, wired is fine. Cell phones still seem very slow. I only managed to get high speed the first day or 2, don't remember exactly how much, but I was satisfied, not any more. 

I have a 3400 sq. ft home, 3 levels. Bell Home Hub 3000 router is in the basement. Construction is pretty standard, more open concept and walls are drywall. I have cat5e cabling from the basement to the office and family room on 1st level and another cable running up to the landing area on the 2nd level.
My old system includes 2 TP-Link Archer C7 access points. But wifi sucks lately (<5mbps sometimes) in the last 6 months or so.
Got the Orbi RBK50 for better wifi and mainly faster internet speed.

I connected the Orbi RBK Router to the Office on 1st level. The Satelite to the landing area. It will be about 30 feet apart or less. I have also tried connecting the Router to the Family room with similar speed. All speed tests were run with ookla.

All speed tests were done late night with no other devices connected.
