finally, I got  6ghz trace file from Windows environment in Japan!!
though dissector is not exported correctly ( wlan_radio.frequency, radiotap.xchannel.freq etc)  for now, but it is a great step to debug 6Ghz ordinally, we do not need to lie I am in US ( iw reg set US) with Linux attached with comfast card, we do not need to have a Sheild room to avoid initial scan to determine contry. I talked to TamoSoft person to fix exporting function of CommViewForWiFi.
now we success with base driver Intel AX210 Driver Ver. or with Windows 11 Pro using TamoSoft driver ( CommView For WiFi 7.3 Build 911) I know all American say oh we got normally last year... but it is a big leap in Japanese air space
