It is the WiFi driver (cfg80211 is "configure 802.11" and ath is the
Atheros driver). Wifi runs in different bands in different countries.
You should not run the US profile in Irelend (IE), in the UK you get 2
more channels[1]. So with a US config it won't work with a IE router
that is using channel 12 or 13.
