For educational purposes we are trying to change the wireless devices txpower higher than domain regulations per country...

To operate outside of specific bands or power levels, we know you have to change the regulatory domain on a given card, but we're not sure how to do it.

We've located the regulatory.bin file but need help changing and editing the information within this binary file!

How should we proceed?

From a terminal:

gksudo gedit /etc/default/crda

Use nano, leafpad or kate if you haven't gedit. Change the only non-commented line to:

REGDOMAIN=IS

Or whatever country code you desire. Proofread, save and close the text editor. Unload and reload the wireless driver:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi

Or whatever your wireless driver is. Check dmesg for a line similar to this:

cfg80211: Calling CRDA for country: IS
