R7000 2.4ghz not working but 5ghz is fine

Great solution Le-Blanc!!!! :smileyvery-happy: 

The solution worked for me.  Had forgotten I had enabled guest on 2.4GHz (turned off the broadcast SSID but left enabled).  Disabled guest on 2.4GHz (guest was never enabled on 5GHz) and did a reboot, now devices are connecting.

Here are some findings I made in addiditon.  2.4GHz would work, if you disabled any security.  I tured it off, rebooted and could connect, but if I tried to enable any security protocol it would not work, always got authentication errors and low signal reports from android and apple products.  Odd it would work without any security defined even with guest enabled.

I had the guest network enabled when I was trying this and found that removing any security fixed the problem.  So now I am wondering if I enabled guest and used security if 2.4GHz channes would work again?  Not adventorous or enough spare time to try and see, that is the job of netgear technicians who should be testing the firmware before releasing it or enabling the silly upgrade from GUI link (yes I did this like the others and found the same results, loss of 2.4GHz).

I am now happily running Firmware Version V1.0.6.28_1.1.83 now on my R7000 but without the benefit of a guest account on 2.4GHz.  This isn't too inconvienent for myself BUT... a product sold with advertised capabilities should always to able to run ALL capabilities as designed and advertised 100% of the time.  Something is wrong with present firmware version that needs to be fixed or communicated in a service notice send to all users outlining: Issue, behavior, work around (disabling guest accounts), reasons for the behavior, and patch/fix time table.
