Ma pensa te sta cosa... (odiosa!)

cmq ho provato a dare un occhio a quello che dicevi tu:

cat /etc/default/crda

# Set REGDOMAIN to a ISO/IEC 3166-1 alpha2 country code so that iw(8) may set

# the initial regulatory domain setting for IEEE 802.11 devices which operate

# on this system.

# Governments assert the right to regulate usage of radio spectrum within

# their respective territories so make sure you select a ISO/IEC 3166-1 alpha2

# country code suitable for your location or you may infringe on local

# legislature. See `/usr/share/zoneinfo/zone.tab' for a table of timezone

# descriptions containing ISO/IEC 3166-1 alpha2 country codes.

REGDOMAIN=
