IEEE_80211_DEBUG is compiled into the kernel. When I ran "wlandebug +scan", I got the following output: net.wlan.0.debug: 0x0 => 0x200000 Then I ran "ifconfig wlan0 up" and then "ifconfig wlan0 scan". The scan now took a few seconds, but still nothing shows up. Then I took a look at dmesg -a which was now filled with a loop of the following messages: wlan0: ieee80211_start_scan_locked: active scan, duration 2147483647 mindwell 0 maxdwell 0, desired mode auto, append, nojoin, once wlan0: scan set 1g, 6g, 11g, 7g, 13g, 52a, 56a, 60a, 64a, 36a, 40a, 44a, 48a, 2g, 3g, 4g, 5g, 8g, 9g, 10g, 12g, 149a, 153a, 157a, 161a, 165a, 100a, 104a, 108a, 112a, 116a, 120a, 124a, 128a, 132a, 136a, 140a dwell min 20ms max 200ms wlan0: scan_task: loop start;
