Whelp, my ticket was closed without an update from Netgear support

These days there are way too many variables in the install process. One of which is the install not working right. Once you can get a good install, following installs that are done as "Dirty Installs", right over the top of the current install without clearing things out, maybe possible without any problems. If you're game . . . do a 30-30-30 Reset on the RBR to hopefully get to a starting place. 

A 30-30-30 Reset is:

1. Open a Paperclip to give you a small pokie thing;
2. find the Tiny Reset Hole on the back of the Unit above the Power Light;
3. you'll be press it for a total of 90 seconds. Do Not let it go; during that time:
4. 30 second with the power connected;
5. then disconnect the power for 30 seconds, still holding in the Reset Button;
6. plug the power back in and leaving the Reset button stlll pressed for 30 more seconds;
7. after that 30 seconds, release the Reset Button and let the RBR come all the way back up.
8. Hold your breath;
9. take a look around in the RBR and see where you're at . . .
10. you can breathe during this part . . .

After the RBR comes back up it will be completely wiped, "Back to Normal" and you'll have to re-enter all your info from scratch. DO NOT use a Back-Up to do this. Especially if you have changed FW versions. This could Brick your device. And if it did work, it could bring all the boogers with it.

Now that you are hopefully "Normal" and have checked to see where this puts you. Maybe, all fixed; and/or ready for reinstalling a new FW; and/or ready to install the new FW using the "Dreaded Install Method". Which is so Dreaded that I can't find where I put a copy of it. But it contains a 30-30-30. That you have already done.

Let us know how you do if you choose to try the above or would like to "YELL" at me for putting you through all that . . . In the meantime, I'll go looking for the "Dreaded Installer Procedure" in case you want to try it . . .

Good Luck.
