antenna aruba authentication: MIC fail

I connected my notebook to the wifi, but sometimes when I transfer my notebook to another room, it loses its connection to the internet and requires me to authenticate again, I close my browser and enter my username and password to access the internet again . This occurs sporadically and with different notebooks. Does anyone know how to solve this problem?

 


I read this link: http://www.arubanetworks.com/techdocs/Instant_40_Mobile/Advanced/Content/UG_files/Authentication/UnderstandingEncryption.htm?SearchType=Stem&Highlight=MIC


MIC is a message integrity check. I collected my logs and found some alarms and errors:
