DHCP issues after reboot

I have the same problem with one sattelite, 40 devices, AT&T Fiber BGW320 for 4 months (prior was Cox cable) . Using an AI as a tutor its helped me move from V 7.2 7 15 , to V 7.2 8 5 on both router and satellite disable WIFI on ATT Gateway, IP Passthru , factory reset twice, when I manually put in the ip address for my LAN 10.0 0 40 and gateway 8.8.8 8 it works great on my TV again, BUT I have to do IP Configuration manually.  the stove, and fridge connect with the Samsung Hub, but no IOT cameras work. Alexa started working, no plugs or bulbs will work anymore.  I'm to the point of Downgrading the firmware which I have read to use

V 4.6 14  3, or even Alternate "Rock Solid" Choice: V 3.2 16 6 . what do you suggest?

    What is the size of your home? Sq Ft?

    What is the distance between the router 📡 and satellite(s)🛰️? 30 feet or more is recommended in between RBR 📡 and RBS 🛰️ to begin with depending upon building materials when wired or wirelessly connected.

    Does this happen with the RBS turned OFF? 

    What channel configurations are currently set on the router?  Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.

     

    Any Wifi Neighbors near by? If so, how many?

     

    Is IPv6 enabled on the RBR? 

    Using ISP detected DNS on the RBR or custom DNS? Try custom like Cloudfare or Quad9

     

    Try the Orbi system in AP mode?

    Disable IP pass thru on the ISP router if you try this.

    There may be some confusion (or perhaps a typo?) in the Original statement:

    If a device (the TV?) has an IP address of 10.0.0.40, then the gateway address is almost certainly 10.0.0.1.  8.8.8.8 is one of the IP addresses for Google DNS.

     

    Could you please confirm:

    • The IP address assigned to the WAN port on the RBR750 router?
    • That the 750 router is acting as a DHCP server and what the DHCP 'pool' range is (start to end)?
    • That the AT&T unit is no longer broadcasting WiFi?
      That no devices in the house are configured to use the ATT WiFi?  (if they are and the AT&T is no longer active, then those devices are "cut off"
