I have an Orbi RBKE962, I recently upgraded my Xbox One X to an Xbox Series X and have experienced the same issues described in this post. My download speeds are in the 1.4Gbps + tested on all devices, phone, laptop, tablet, PC... The Xbox Series X, the fastest speed I've gotten is 200Mbps. I spent a few hours on the phone with Xbox, no resolution other than there some type of incompatibility with the Xbox devices and the Netgear system. I spent quite a bit of time on the phone with Netgear as well. Finally, after several weeks, this is the response I got from Netgear...
"Please be informed that the Xbox Wi-Fi client is not an AX, it is only an AC. This could be the issue since they are under a different protocol as advised by the expert from the higher department. The Orbi System is operating in AX (Wi-Fi6)."
I would think that the 960 would be backwards compatible, but I guess its not. So... it looks like the only solution to slow speeds on the Xbox, is for Xbox to upgrade their system to be compatible with 802.11AX.
I have had both Xbox One, now a XB1 X and a series X. Any of these models have never seen much over 400-500Mpbs on any of my NG routers, Orbi or Nighthawk. Xbox wireless have never been on the bleeding edge of wifi and have only been or seems to be designed with the average general wifi specs. Since the wifi is AC on game consoles, and probably limited to 80Mhz channel width, this will be limiting to wifi speed performances so you'll never see anything near 900mpbs or beyond with these wifi radios in the game consoles. And honestly, gaming and gaming traffic isn't a major bandwdith hog anymore. Most all gaming just needs maybe 500Mpbs on the down and 50Mpbs on the up. 50Mpbs works well for me and I'm one of two games in the home.
If you want to see better speeds and performances on any game console, use ethernet connections. Will always out perform wifi.
