Try to gracefully shut down the card after sniffing... this is a temporary

hack until the colleagues implement this in libwellenreiter...

 To compile Wellenreiter within the Opie build environment, add the
 following directories to $OPIEDIR/Makefile, e.g. to 'NONAPPS='
 
 noncore/net/wellenreiter/libwellenreiter \
 noncore/net/wellenreiter/daemon \
 noncore/net/wellenreiter/contrib/orinoco_hopper \
 noncore/net/wellenreiter/gui
 
 ./configure and rebuild. Note that you need libpcap in your toolchain.
 
+To compile Wellenreiter within the OZ build environment, add the
+following lines to $OPIEDIR/packages

 =====================
 =       Run         =
 =====================
 
+There are two possible modes: <Manual> and <Automatic>. I suggest, you
+start with the <Automatic> Mode. This works just using the "Start"
+and "Stop" Pushbuttons in the Wellenreiter GUI. If this doesn't work,
+then use the following strategy:
+
 1. Place card in monitor mode. This is device dependent.
 
    Caution: Don't do this while you're logged in via ssh
    or otherwise using the wireless interface - your connection
    will freeze: The card can't be used normally when sniffing!
 
-   For most orinoco-based cards this can be done using
+   For most orinoco-based cards this can be done using either
    'iwpriv <interface> 2' or 'iwpriv <interface> 2 1'.  
    
    You can check if this works, by calling 'ifconfig <interface>'.
    If you see 'Protocol: UNSPEC' and an unusual long MAC-Address,
    then your card has been successfully set to the monitor mode.
 
 2. Start a channel hopper. A wireless card has several channels
    (e.g. radio frequencies) here it can listen for beacons.
    Beacons are management data frames from other stations.
    Remember, this is radio transmission, so the card has to be
    "tuned" to a certain channel to be able to receive the beacons.
    
    In order to scan the complete frequency spectrum and thus be able
    to detect all available stations, you have to 'hop' through the
    channels frequently. You can do this manually (e.g. with 'iwconfig')
    [hahaha] or you can use a channel hopper.  
    
    For convenience, the current Wellenreiter Alpha comes with a 
    channel hopper for Orinoco-based cards. Start this via 
    orinoco_hopper <interface>.
 
 3. Start the Wellenreiter sniffing daemon: wellenreiterd.
 
 4. Start the Wellenreiter GUI and sniff like hell. Don't press the button
    "Start Scan" yet, because it enables the demo mode and will crash the
    wellenreiterd daemon if running.
