Wifi not stable and disconnect in iPhone & Andriod devices

[itd_steve]

Our company have built a large Wifi network with total 74 APs (AIR-LAP1142N-N-K9 & AIR-CAP2602I-N-K9) connected to Cisco 5508 Wireless Controller.

Primary Software Version   7.5.102.0
Boot Version   12.4.23.3
IOS Version   15.2(4)JA1$
Mini IOS Version  7.0.220.0
 

4 APs in each floor are unstable and always disconnect with iPhone & Andriod devices.

I have try to reduce the power level in APs. But it seen problem still occurs.

Hope You can help me.

Upgrade your WLC software version to 7.6.130.0

Also upgrade FUS image to 1.9.0.0 (this will take 30-40min downtime & do it via CLI)

Things would get better with this new code.
