Comment:
so i digged a bit in wifi-radar

I own an atheros based D-Link DWL-G650
I has to be brougt up for scanning etc.
if the card is up wifi-radar works even with the LC_MESSAGE statement
if my card is down (after boot or after wifi-radar stop)
the card won`t come up with that LC_MESSAGE without it all works fine seems ther is a command-spawning problem im line scanning_thread
«if IFUP_REQUIRED» 

seems os.spawnlp does not work with the prepended LC_MESSAGE statement
othe calls to ifconfig go thru os.system() or os.popen()

the networkshutdown with iwconfig also goes thru os.spanwlp and nothing
is cleaned up
