Determine if PKMID is dynamic?

Hi all,

I've used hcxcaptool to capture PKMID's from my home network router. I succesfully captured 2 (there were 2 clients connected at the time). After converting it into hashcat forma,  the issue I have is that I've used hashcat and a wordlist with my password in but the hashcat does not recover it!

I read that the attack vector won't work on devices that don't use PKMID caching, I suspect that is the issue I've got? I've ran whoismac on the 16800 file and I can see that it is indeed the correct SSID / Mac address.

Is there any way I can prove that the device is not reusing the PKMID?

Thanks
