I found it. :)
The problem is the following code:
[drivers/net/wireless/ath9k/main.c, ath9k_configure_filter(), line 2399=
]

if (changed_flags & FIF_BCN_PRBRESP_PROMISC) {
        if (*total_flags & FIF_BCN_PRBRESP_PROMISC) {
                memcpy(sc->curbssid, ath_bcast_mac, ETH_ALEN);
                sc->curaid =3D 0;
                ath9k_hw_write_associd(sc);
        }
}

On scanning the BSSID is set to the broadcast MAC, but never set back.

Im not sure how to fix it in the cleanest way. I know to less about the=
 handling of multi interface devices. ath9k people can you help please?

Thanks
Alina
