Trying to do 'sudo iwlist scan' tells that device is busy. it seems that at first nm connects, as it receives first scan results. but then it can't scan again - probably something in scanning code is broken so it never finishes a scan. My AP is WPA-2 protected. Also I noticed long ago that wpa_suppicant doesn't connect to the network at first try since ts wpa handshake fail. This is probably its bug, but just for reference - this is very annoying. (I use latest nm and wpa_supplicant from -git - but this problem have always existed). And of course I noticed another very strange bug with iwlwifi. At my university often I can't connect to the wifi - usually because of the week signal - but at some rooms I noticed that if I somehow manage to connect (get dhcp address that is) - connection is very fast and stable. In other words association usually works (forgot to say that they use open network - duh ), then DHCP stalls - but if it succeeds and I move to different part of the class - even where I never had any reception - it continues to work well. (It could be that transmission speed is lowered - but I tried to set low speed - and never got any better results) Thats all for bugs I have on my intel wireless - keep up the good work - recently iwlwifi drivers improved a lot. (even the led blinks correctly now in monitor mode) Best regards, Maxim Levitsky
