No results. If you don't show what you do then I cannot tell. You don't include the wlan debug msgs that show the directed ProbeRequest frames so I cannot be sure they are going out. If they are not sent then the ap will not respond. If you set scan_ssid and you're not seeing the ProbeRequest frames then you'll need to figure out why. > I do not know much logic WiFI, perhaps the problem with disassembly > beacon packet of access point? > > Or, more likely to parse the answer to the AP on ProbeRequest from FBSD? > > What is?... > wlan0: [00:23:5e:75:f7:c2] discard unhandled information element, id > 133, len 30 This just means the beacon frame included an IE that was not handled. You appear to have to have enabled "elemid" debug msgs. Samhome | help
