Orbi V2.0.0.74 - iPhones constantly losing Internet connectivity (but not WiFi connectivity)

I've been having these same issues for the longest time, even on different versions of firmware. Right now it seems the worst on the latest...so bad that I opt to just use my cellular data; which is ridiculous to have to resort to. 

Turning on wifi and then off sometimes fixes it; lately, not so much. Speedtest results off my iphone are highly variable. When it works I'm over 150mbps+ download speeds then when watching videos it starts lagging. I've noted download speeds as low as 0.03mpbs when it was the previous just minutes before. When that happens, I do a power cycle of the router and it works again; abeit temporarily.

Maybe it's an issue of jumping between the router and the satellite that screws things up. Or maybe its because I've used the speedtest feature within the orbi interface in the past that screwed something up and still lingers.

I've brought down the 2.4ghz channel power down to 50%. Any lower and my netgear arlo q or ring doorbell starting losing connection.

I've read before on here about clearing svram files or something like that if ever using the speedtest feature on the interface...maybe that's the issue? How do I do that, would a router reset essentially do the same thing?

I am also considering putting my orbi in AP mode as a possible solution...would that remedy this iphone issue? 

MIMO and beamforming are off as default with the latest firmware.

Someone please give me some advice on how to get the bottom of this. Thanks in advance!
