Jednoduše to umí odrbat a to bude zásadní. Tipuju, že nejspíš na úrovni systému, aby mohli ty karty nakoupit kdekoliv.
CM9 mám taky ve starém RSPro, kde je upravený Debian (DebWrt). Tam ji dokážu přehodit např. na CZ:
root@debwrt:~# iw reg get
country 00:
(2402 - 2472 @ 40), (3, 20)
(2457 - 2482 @ 20), (3, 20), PASSIVE-SCAN, NO-IBSS
(2474 - 2494 @ 20), (3, 20), NO-OFDM, PASSIVE-SCAN, NO-IBSS
(5170 - 5250 @ 40), (3, 20)
(5735 - 5835 @ 40), (3, 20), PASSIVE-SCAN, NO-IBSS
root@debwrt:~# iw reg set CZ
root@debwrt:~# iw reg get
country CZ:
(2400 - 2483 @ 40), (N/A, 20)
(5150 - 5250 @ 40), (N/A, 23), NO-OUTDOOR
(5250 - 5350 @ 40), (N/A, 20), NO-OUTDOOR, DFS
(5470 - 5725 @ 40), (N/A, 27), DFS
jenže stejně je pro 00 i CZ tabulka kanálů stejná:

tzn. že na 2,4GHz ji na 12+13 kanálu jako AP nezapnu (pro ČR to je blbost) v 5GHz pouze indoor (36-48 kanál).
