When R850 upgrade to Unleashed 200.18.7.1.302 from 200.17.7.0.152. then some 2.4G smart home device will be officeline (2.4G & 5G is same SSID, and with 30+ smart home deivce, Most of them are 2.4G devices.) . If downgrade to version 200.17.7.0.152, no this issue.

@biniyi,

If the product has support warranty, could you please raise a support case on this.
I might need some additional data to see the issue.

If not, let me know so that I can guide you to collect the necessary logs.

Try Enabling WPA2 and WPA3,  I had this issue on the 5ghz, it was some devices not supporting WPA3, and needing WPA2,  but I had that turned off.  When I enabled WPA2 (made it the same password as WPA3 so I would not have to enter new passwords for everything) it all worked.   I have no idea on why 200.16 it worked, and in 200.17 it didn't - but something for sure changed with how WPA2 and WPA3 support is designed.  In my case the manufacture (Control4) said there was never any support for WPA3 for their remotes, but I had them working perfect with ONLY WPA3 enabled on SSIDs.  Hopefully this helps you.  Wondering if this is also your issue.  They said this specific issue was fixed in 200.18 - but I have not tested to confirm, I left my config with WPA2 and WPA3 on.
