Comment 9 for bug 365049

This is an upstream issue as clearly stated in the kernel wiki.

“Using Network Manager to change regulatory domains

This needs to be implemented, but since Network Manager uses wpa_supplicant it should just be a matter of adding a user interface option to let a user select an alpha2 and then adding the country entry into the wpa_supplicant configuration entered.”
