Is there any kernel output during this time?

So the USB adapter does work with 6.18? Do you have any other adapters 
to try? Does wpa_supplicant + iwlwifi adapter work on 6.18?

Trying to determine where the issue is. To me, if a USB adapter works 
that tells me its not necessarily an IWD issue, but something with 
iwlwifi and that kernel version. I'd be most interested if 
wpa_supplicant + iwlwifi works, if so we can try getting some iwmon 
logging of the two setups to see what differs.

Thanks,
