RBR20 constant connection issues

I’m dropping the switch and time capsule out of the system. I had the time capsule setup correctly so the radios were off but when I used a WiFi scanner it was tagging the router as the Apple time capsule. So I removed it from the system and it cleared up a good bit of the issues. The Xbox is only getting 40 ish mbps download. Once test it jumped to 140mbps but that was only once. It’s enough to stream through it and not get constantly disconnected.

Thanks for all the help and suggestions.

So the recap was first part of the issue was the modem (bad chipset) and second the old time capsule that was being used as a external hard drive was somehow high jacking the orbi (even though the radios were shut off).
