ORBI showing connected but no WIFI, Modem going offline occasionally

Equipment: ORBI RBR850 and a CM1000

I am having WIFI connection issues. My WIFI will be great then it will drop a few times and completely go out. It shows me as connected to WIFI but there is no connection. I do have access through my hardline from the router to PC but no acess from any other deivce connected through the router ports (switches,  xbox, home automation ect). Sometimes I have no connection at all through my hardline and my ISP shows my modem as off line. I swapped out my old CM1000 for a new one just in case it was modem problems and the problem still persists, so I dont think it was my modem. When the connection goes down I can sometimes connect with the hardline and it tells me my WIFI is connected not my devies have no signal, factory reset does not help. Actions I hae taken are

1. New modem

2. Tried a new Router (AX8), that worked

3. Adjusted rts/cts threshhold settings

4, Used a static DNS, was having lots of DNS errors

5. Changed out cables (I kept getting no connection check wires, may be broke messages)

6. Factory resetting of modem

7. ISP resets 

*Note that the resets sometimes did work but not all the time, no consistancy*

    What is the size of your home? Sq Ft?
    What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router

     

    What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
    Any Wifi Neighbors near by? If so, how many?

     

    Try disabling the following and see:
    IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).

    Be sure that CTS and RTS values are changed to 2346 under Advanced Tab/Advanced Settings/Wireless Settings

     

    What happens if you disable AX Mode?

      I have had no drops in 24hrs

       

      What is the size of your home? Sq Ft? 5000
      What is the distance between the router and satellite(s)?

      -1 satellite and distance between them 1-200ft (if I have to setup again I will use the reccomended 30feet for pairing)

       

      What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
      Any Wifi Neighbors near by? If so, how many?

      -Using auto channel but I did change it while troubleshooting while it was acting up (made no difference) a couple WIFI nieghbors maybe 2-3 but are good distance apart

       

      Try disabling the following and see:
      IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s) Be sure that CTS and RTS values are changed to 2346 under Advanced Tab/Advanced Settings/Wireless Settings- 

      -These are my current settings

       

      What happens if you disable AX Mode? I have this disablded and not seeing any drops/loss of connection (and it was yesterday I disablded this so might be a connection between my problem and AX mode)

       

      I am almost certain this has something to do upstream since I am getting no consistantcy in errors. If this was a hardware failure or software I would get soe kind of consistancy. I will keep monitoring this amd keep this post updated if I have any changes

        200 feet is a bit too far for RBS. 

         

        30 feet is recommended starting placement distance at it's remote location. Depend upon building materials, 50-60 feet is a remote distance range for RBSs. Pairing distance can be in the same room with the RBR. Once placed, then put out at it's remote location. 

         

        I have my RBR 2nd story and RBS in the basement at about 35-40 feet in a 5000sq ft home.
