@lhari84 Hi, You can take a look on this page: https://github.com/recalbox/recalbox-os/wiki/Wifi-country-code-(EN) So basically "FR" code has a larger range than "US" range, but because this is a standard and to be compliant with US authorities, US is the default. About the "system security" feature, my advice is you shouldn't enable it as it's bugged and has to be rewritten.
