Which is > less often than we'd hope. so your are suggestion to use ap_scan=2 and add scan_ssid=1 to the network block? nm seems not to do this. btw shouldn't all mac80211 drivers either work or not work because the code for this is in mac80211 and not in the drivers? I will be able to test again this friday will try this and the ap_scan=1 if there are other suggestion feel free to say them so I can add them to my "totest" list ;) - 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
