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.

 =====================
 
+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.
