Hi,

Fast BSS Transitioning decryption is unfortunately not supported by Wireshark.

Wireshark uses passphrase/PSK/PMK together with 4-way handshake to derive PTK and GTK. FT key hierarchy and key 
derivation is not handled by the decryption engine so PTK remains unknown which makes decryption fail. And 
unfortunately directly entering PTK for decryption is not supported either.

It could be but it would take some work :-)
