The bug would rarely be seen, except that some cable modems hand out private IPs when the connection to the ISP goes down.
This sort of thing, erratic local IP addresses, can also happen if a modem goes down and boots so slowly that if has not made an internet connection before the router kicks in.
If the router can't see the modem, it goes its own sweet way when it comes to selecting an IP address.
In my case, it was when recovering from power cuts that I hit this brick wall. The local network failed to connect to the internet.
This is probably not related to what is going on here, but it does illustrate that subtle interactions between devices on a network can throw things into a tizzy. It may have nothing to do with Netgear's evil firmware.
I agree,
garrettg84, I think that you can easily solve your issue by keeping the private address on the ISP modem so the interface to Orbi keeps always a private address..
Using bridge (passthrough) in the modem seems not working for you since the modem will -momentarily- change to private address when it looses the internet connection and then gets back the public IP address which confuses Orbi.
If you have access to your modem (or if the ISP can help you with that) then I suggest to remove the passthrough mode and instead use DMZ forwarding. This way the modem will keep the private address network and the DMZ forwarding will take care of the double NAT.
