Hi Guys,
i am having few scanner machines which are connected to SSID through WEP authentication.
But now i am moving these machines to new SSID with WPA2 authentication. i have created new SSID with WPA authentcation but machines are getting time out error on new SSID and reconnecting back to old SSID.
i have attached logs. Can you please help here to know issue?

Hi
It seems to me that you need to disable Fast Transition on the WLAN:
11r AKM support verification failed on WLAN
Your client got associated and Authenticated more then once but it drops apparently due the fast transition enabled.
