Additional interfaces are broken currently for zd1211rw. I cannot fix all the problems with mac80211 interface of the driver at the same time. Try iwconfig wlan0 mode monitor ifconfig wlan0 up iwconfig wlan0 channel 6 for now. The problem with the STA + MNTR interface is, that mac80211 must do the FCS checking for the STA interface or the driver has to filter them before forwarding them to the upper layer. -- Uli Kunitz - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
