Change regulatory region

You can change the regulatory region by installing the iw and wireless-regdb packages.

To get current region run:

$ iw reg get

You can set the regulatory region to the UK with:

$ iw reg set GB

The list of country codes can be found here: https://content.cisco.com/chapter.sjs?uri=/searchable/chapter/www.cisco.com/content/en/us/td/docs/wireless/wcs/3-2/configuration/guide/wcscfg32/wcscod.html.xml

Finally, to apply your changes, restart the wifi modem. This can be done with the following commands:

$ rfkill block wlan
$ rfkill unblock wlan

Or, in Sxmo, you can use the wifi toggle from sxmo_appmenu.sh -> config menu.

Your wifi should work now!

These changes are not persistent after a reboot.

To make this persistent, we create a new service script:

/etc/local.d/wifi-country.start

which contains:

#!/bin/sh
iw reg set GB

remember to make it executable:

sudo chmod +x /etc/local.d/wifi-country.start

thats it, reboot and check if your wifi country was set.
