XBOX One and network dropping

Hey so I just bought and Orbi (and a Velop, which is constant to overall too slow). The Orbi is much faster BUT I am having 2 issues... 

BTW, I am on the latest firmware and have 300 down and 20 up.

1) Xbox One (both original XB1 and the Xbox One X)

- Wireless - even though it has 100% signal strength, will not get more than 40 mbps download

- Wired - will hit the max speeds available

2) Random system drop outs that effect wired and wireless. I go from 100% perfect signal to 0 in an instant. This shuts off the wireless and the wired model. My son was playing Xbox, while wired since the wireless kept disconnecting, and it still booted him from the game saying he lost his network connection.

I noticed that if I activate beamforming or the MU-MIMO (or whatever it is) that both of those majorly slow down the network and I have to turn them off... (isn't that stuff supposed to make it faster?) IPV6 is activated also. I disabled Daisy Chain as well.

How can I fix this? Going nuts here. I'd like to keep the faster system but will have to opt for the slower Linksys model because it's more consistent unless somebody can help me.
