R7000 problems since latest firmware update - which firmware is stable/should I revert to?

I'll give that a try.  I'll try that on my r7000 that I already upgraded, too.  My wired PC passing through the r7000 that I already upgraded has terrible internet (download) performance at 1-3MB vs the 100MB+ I should have.  When I bypass the r7000 and go straight to the modem, I'm back up to 100MB.  I'm hoping firmware is the issue. 

It sounds like I have the same problem MANY other r7000 owners are having with degraded internet performance.  Since this issue has been documented going back to early 2015 or even 2014, for most owners the degraded performance occurred >90 days after purchase. So all we seem to be getting from NETGEAR is the standard "We know there are issues with the r7000s and we're working them.  However, we can't troubleshoot you without swiping your VISA for a cost well on the way to a new router that probably won't have these issues."

How can NETGEAR even be selling the r7000s knowing that there are lingering serious problems with them?  Anyway, I'm hoping that reverting the firmware 'fixes' my issues so I don't have to save up for a replacement quite yet.  Also, I was going to go for one of the newer Netgear range extenders, too, but if the r7000 is not going to get me the advertised performance, this will be useless.  I'd like to hang in there with Netgear as a relatively long-time customer, but these issues certainly give me pause on future purchases.  Anyone from NETGEAR wish to respond?
