It does, thanks! "list scan" gets populated after I -mediaopt monitor after scan; module reload is not required anymore. Do I read you correctly that seeing no results for "list scan" is OK while card is in monitor mode? > On a side note, you should never be required to run 'ifconfig dev scan', > because after 'ifconfig dev up' the device is always in SCAN state (at least > in station mode). Using 'ifconfig dev list scan' is sufficient enough. Certainly. I was meant to say that "list scan" returned no results, and "forcing" the scan (despite that background scan is in progress) would never return either. > It might be possible with lots of ugly hacks to get that device sending some > kind of frames, 'injecting' those frames via net80211 shouldn't be that hard. > At least the code is there according to comments in ieee80211_output.c.
