1. `iw reg set JP` is exactly what this regulation seeks to prohibit, i.e. if you are selling WiFi hardware in the US, you have to be damn sure that no one will be able to switch it to channel 14.<p>2. Even with `iw reg set JP` you won&#x27;t be able to go above channel 11 if your system contains an Atheros adapter certified for US market only. Even using other hardware, suitable for the job and certified by whatever agency Japan has.<p>The only solution is `rmmod ath` or patching the mac80211 stack. Or avoiding Atheros hardware, as I do. Not that I have anything against Atheros, I&#x27;m sure they wouldn&#x27;t bother implementing this bullshit logic if they didn&#x27;t have to, but their hardware is simply a PITA to use because of this.
