Hello Adrian! Thanks for the idea. I tried with just "ifconfig wlan0 up". Indeed it seems that the "scan" =20 is redundant, as wlandebug output shows that a scan is started =20 immediately after I issue the "ifconfig wlan0 up" command. Alas, the =20 scan result is still the same as in my original message, and "ifconfig =20 wlan0 list scan" shows no results.
