Not able to record pings during handover scenario

I am having problems with recording pings. Following is my scenario.

Sorry?? What is the issue here??

Sorry?? What is the issue here??

The issue is that handover is not able to ICMP using WPA2 encryption. Without encryption, handover is working.

[ramonfontes]

Is not able to ICMP? Did you install BOFUSS??
