On latest current: man wpa_supplicant has no '-a' & There is no word `active` in man wpa_supplicant.conf I see with default scan_ssid=0 FreeBSD sends a broadcast Probe Request frame. If some network blocks within a wpa_supplicant.conf have scan_ssid=1 then does FreeBSD actively sequence through sending directed Probe Request frames with known net names ? Or are you refering to ap_scan or some other command ? Cheers, Julian -- Julian Stacey, BSD Linux Unix C Sys Eng Consultant Munich http://berklix.com Indent previous with "> ".
