For whatever reason, the United States' FCC doesn't allow wifi users to broadcast on channels 12-14. However, I'm sure the hardware supports it (RTL8188CE). If I'm traveling outside the United States, is there a way to enable the other wifi channels over 11?
I'm not entirely sure, but I think the
CRDA (Central Regulatory Domain Agent) should change itself based on your localization in system.
To change it manually use:
% iw reg set
<country code here, e.g. JP>
