You can use below debug analyzer tool to analyze your output

https://cway.cisco.com/tools/WirelessDebugAnalyzer/

Below shows some analysis for the client debug of mac address 80:ea:96:e0:ac:54

I can see client connection flaps between 5GHz & 2.4GHz. Is it possible to test this on one frequency band (either WLAN to set on 5GHz or client set to prefer one band over the other)

1. First connection attempt on 5GHz

2. As you can see below, same client move to 2.4GHz on same AP (see the BSSID difference)

3. Again client move back to 5GHz

4. Again you can see a flap

I disabled the 5 Ghz band, now.

new my debug.

For this client, I only see

Rasika Nayanajith — Wed, 18 Jan 2017 02:39:51 GMT

For this client, I only see one successful association.

However this client, I can see multiple associations to the same AP. This mean same issues still there. Actually connection 1 & 2 with two different AP. Connection 2,3 & 4 with same AP

I disabled the 5 Ghz band, now.

Can you do a similar test on 5GHz (while 2.4GHz is shut) & see problem persist

I am also facing the same issue of client flapping between 2.4 and 5 Ghz radio on same access point. What could be the solution.
