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).

2.4ghz is auto and 5ghz is set to 48. I’ve tried all the combinations of 2.4ghz 5ghz and still have the same issues. I have multiple networks around me of varying strength. I’ve adjusted my radios signal strength as well.

Beam forming and WMM are enabled, daisy chain and fast roaming are off. I’ll have to double check IPv6 when I get home. The 20Hz/40Hz button is checked, does deselecting it turn it to 40hz only?

I just factory reset the router Sunday evening.

Yes.

Sounds like even if you have tried all the troubleshooting suggestions, you may have a faulty or bad RBR.

    New router is setup, same issues.
    swapped out my modem this weekend from the SB6190 to a netgear CM1000 since I read there were serious issues with the SB6190 because of the chipset, still same issues.
    
    I'm not really that savvy in troubleshooting a network. All I have is my wifes macbook and my xbox one and I'm not really sure how to run tests or diagnose with the macbook.I ran a few network tests on my xbox and had acceptable upload and download speeds, 70ms latency and between 0-42% packet loss over 8-10 tests (I tried this wired to the switch and to the orbi). I figure it isn't really a great way to test but it's what I had at the time.
    
    We never really had issues with our old apple timecapsule router, we just couldn't get internet in the office (which is were my wife needs it the most for work).
    
    Any recommendations on how to test my network to run down what's causing all my network woes?
    Is there a way to rule out the router and then the modem?
    Are there tests I can run and provide spefic data to help with troubleshooting?
    
    any help would be greatly appreciated and all help up to this point has been greatly appreciated.
