Hi Camaleón,

thanks for the additional information you provided.

Interesting observations. Ok, lets keep this in the back of our minds 
but first focus on the bad scan results.

next to the AP).

Hmmm, so it seems that rfkill switch functionality is not causing the 
bad scan result.

Can you try to disable Bluetooth (e.g. by temporary blacklisting the 
bluetooth modules) ? Bluetooth operates in the same frequency band as WiFi.

Would you happen to know if with kernel 2.6.39, the brcmsmac driver was 
active as well (and not a different driver) ?

Lets shoot for that as well :-)

Thanks, Roland.
