The command 'iw dev wlan0 scan passive' doesn't print any output. At the same time, a usual scan with sending probe requests ('iw wlan0 scan' or 'iwlist wlan0 scan') does work as expected. The radio module I'm using is 05:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01) Copy of dmesg, lspci, lsmod, 'iw phy0 info' outputs and kernel config file is attached. P.S. I'm not a developer nor programmer, but I'm ready to help to make linux better :) -- Ravaillac
