Failed WPA2-AES handshake on wlan

[Bruno_Amarante]

I'm seeing several "failed WPA2-AES handshake on wlan ...." in my logs for multiple devices on AP7522/AP6521 adopted to RFS6000 running 5.8.3.1 and the WLAN is running TKIP-CCMP. I can see the device failing the handshake every 15-30 seconds on several different APs.

I am in the process of changing this infrastructure but wanted to know if there's something I can do in the meantime.

What are the main reasons for this?

Thanks in advance
Bruno

Hi Bruno,

try to avoid use of TKIP.
Some devices won't respond to EAPoL calls while support for TKIP is maintained.
