R7000 - wirless turns off and won't turn back on

This is driving me nuts:

Quick note:  This has never happened until the latest firmware.  (I was going to downgrade and see what happens - but figured I'd make a post here first before doing that).

So here's what happened:  Seriously a year ago or so (when the latest firmware dropped), 3-6 months after updating my router my wireless with turn itself on - and no matter what I do, I can't get it to turn back on.  The only fix is to reset the router (via the pin hole in the back) and reset everything back up again. 

The second time this happened, I made a few changes back to the way it was (turning off SSID, changing the SSID name and password, mac address (plugged into a cable modem) etc...  readded my port forwarding stuff - and made a backup of the router settings.

And it happened again today.  I used the internal reset to factory default - and noticed it still had wireless turned off.  I tried loading the config and it was still off.  So, i took a pin to the reset button in the back, reset everything back to the way it was and wireless is magically back on....

So why do I keep having to reset via the pin hole to get wireless back on every 4-6 months?  Any suggestions?
