Tool/software: Linux

Hi,

I am getting Michael MIC failure message for client connected to Wilink access point mode. After Michael MIC failure client will get disconnected.

What is reason for MIC failure & any hostapd or other configuration parameter we can check to ensure right client will not get disconnected.

Client is not sending very huge size of file during transmission.

Thanks
