Follow attached the kernel log and output of 'iw list'

Looking at the kernel long I see you are using the hybrid wl driver.
This driver is not what we (brcm80211-dev-list) are supporting. Despite
that and the surprising fact that Brazil is part of the EU, it seems
channels 12 and 13 are enabled.
Could you try the brcmsmac driver instead?
