Netgear R7000 reboot and reset issues

I have read many discussions on the Nighthawk A7000 constantly rebooting and/or users unable to reset.  Solutions range from the recycle bin to a complicated software update - which of course does not work if the router will not reset.  I found a very simple error / solution after an hour of aggravation: I had reversed the AC adapters for the CM700 and the A7000.  The A7000 needs at least 2.5 amps output (P/N 332-10758-01).  The 1.5 amp adapter worked ok for quite awhile, but when this issue arose, and I realized / corrected the error, the A7000 booted up correctly and the reset button worked.
