Comment 23 for bug 1437913

@sforshee - I'm trying to better understand the consequences of Ubuntu currently having an "an old regulatory database version", as some System76 customers are having WiFi problems when connecting to AC routers with an Intel 7265 and `sudo iw reg set US` seems to fix their issues.

In particular, should a regulatory domain be set automatically once the database is updated? Currently I'm seeing the world-regulatory domain (ie, not set), which seems to be an intersection of all domains and means some band that could be used aren't (in the US anyway).

FYI, for anyone experiencing this problem, you can permanently set the reg by editing /etc/default/crda like this, replacing US with your country code:

# 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=US
