RBK50. cannot connect to wifi/internet for mobile devices after power outage. Laptops are ok

What Firmware is currently loaded?
What is the Mfr and model# of the ISP modem the NG router is connected too? 
Is the Orbi system operating in Router or AP mode?

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

Try enabling Beamforming and MIMO(MIMO may or maynot be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings

Try disabling the following and see:
Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).

Has all android devices been powered off then back and to see if they will re-connect? 

Has a proper power OFF of the entire Orbi system for 1 minute, then back on then see if the android devices connect?

After a brief power outage, all mobile devices (all android based) in my network will fail to connect to wifi (wifi will have no internet). While macbook and attached computers can connect.

 

This behavior will continue for about 3-4 hours and then the connection usually will be restored as usual. I have tried to turn off all the router (Orbi is behind my ISP router on fixed IP) and turning it on again.

 

I am using channel 1 for the wifi, as it's the vacant channel in our environment.

 

This is driving me crazy as different behaviors were displayed for mobile devices and laptops. Is there a way to reset  all t he connected devices to ORbi ???

 

Thanks for your help
