Anyway, I was more thinking about use of active scanning on 2.4 GHz band and that would be more applicable for Probe Response frames. > Don't know really... If you are associated to an AP and hear its beacons / probe responses on another channel you really have a big problem in your radio? Is this only for the case of Beacon/Probe Response frames from the AP with which the device is associated? The commit log seemed to imply that this is for all Probe Response frames. I have no problems with the Probe Response from the current AP being ignored from other channels; it is the case of finding other APs that I'm much more interested in in this context. -- Jouni Malinen PGP id EFC895FA -- 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
