In the two radio profiles used by the AP, are you using load balancing and/or band steering by any chance?

I believe the enforce setting is what is causing that issue. Clients will see the SSIDs broadcast but are forced to use the 5GHz in that mode. If you want to force clients to 5GHz, personally I’d disable the 2.4GHz (either through AP interface, set the AP to dual 5GHz (model dependant), or via the SSID settings).

Alternatively, switch this to encourage so that the AP is prioritising them joining the 5GHz, but after the number of connection attempts is reached, the client is still then able to join the network on the 2.4GHz.

I see high collision in 2.4Ghz and for 5 Ghz it is good.Technically if it is connected through 5 Ghz the connection will be good.

I have verified there was few options enabled by my colleague to increase the sensitivity of the connection that technically caused problem. Good intention led to misery unknowingly.

Disabled the suppress response to broadcast probe by

(>) reducing response to certain client devices

And also disabled exclude channels

And customized Radio and Rates by ignoring 2 Mbps 6 Mbps 9 Mbps as NA

After doing above changes the connection is stable and no one reported any issue for last 3 days.

And issue is resolved now.
