Sets the wireless card's regulatory domain to France. Why would that help?

It will open channels 12 and 13. If memory serves me, In USA you can only go up to channel 11, in Europe you can reach channel's 12 and 13 (this I know for sure, I use them) , and in Japan you have access to all the 14 channels.

Apparently you did not research far enough.
I am encouraging and empowering you to find the answer.
Don't give up so easily.

Edit the "options" file located in:

/etc/modprobe.d/
(Use nano or any similar command line text editor. Need to be root or use the "sudo" before the command...)

sudo nano options

and add these lines in the end...:
(Note that you may need to change the name of the module in the
example for your card's module, the one below is for broadcom)

options cfg80211 ieee80211_regdom="JP"
options B43 ieee80211_regdom="JP"

after that:
(change the "wlan0" for the name that iwconfig shows you)

sudo ifconfig wlan0 down
sudo modprobe -r b43
sudo modprobe -r cfg80211
sudo modprobe cfg80211
sudo modprobe b43
sudo ifconfig wlan0 up

That's gonna unlock the 14 channels.

EDIT: Works fine on BT4 Beta / Pre-Final / Final.

Enjoy.
