Hm... I see now. 802.11d is disabled at the moment. Perhaps I've to move this setting to the web iface.
You could try adjusting nvram variables:

To force 802.11d setting:
Code:
nvram set wl_reg_mode=d
nvram commit
reboot
To force 802.11h setting:
Code:
nvram set wl_reg_mode=h
nvram commit
reboot
To disable regulations:
Code:
nvram set wl_reg_mode=off
nvram commit
reboot
