I think I have to set a regulatory domain for my usb ath9k module because it appears to think it is in CN, which I’m assuming is China.

Wow, that’s a lot better! But does it survive a restart? This post describes how to update crda (udev rules) and hostapd.conf.
Basically:
- add country_code=US to hostapd.conf.
- Edit /etc/default/crda so that REGDOMAIN=US
- Edit /etc/modules.d/cfg80211.conf and add “options cfg80211 ieee80211_regdom=US”
This is not a simple thing. I think I might have a busted regulatory.bin file?
