Ok...answers...
First...ignore the errors when installing those libopies. I checked and they install anyways. Don\'t worry about the debian-binary, it just a text file in the ipk. The reason it says it fails is is the package runs ldconfig which the zaurus user cannot run, only root can run it. If you edit the qpe.sh script first as I described above, then reboot, the packages should install without the error. But nevertheless, they install...even as the zaurus user...you just get that ugly message.
Second...once you get everything installed...go to a prompt and type in:
cardctl scheme CardResume
cardctl scheme qpewlan0
cardctl reset
Then start wellenreiter. Go to the config screen and select your driver. If you are socket/symbol based, then select orinoco, otherwise select the driver you use. Save the settings. Then select start. It should start sniffing and you should start seeing activity. if you don\'t, select stop, then select start again. once it running...its sweet. If you get it to that point, I can post a script and a change to make to the App parameters to make launching it more easy.
Also...for the signal low...this is not a driver problem. Its a problem in the network applet. The network applet expects the driver to report in percentages, and it does not (although I guess we probably could change the driver to do so...something to think about). You can take the applet from a SL5600 and replace the plugin applet in a C760. This will fix the problem. However, you may also need to copy over the libsl.so file...and this gets more complex as other things need to get hacked. If Sash\'s 1.18 ROM did not fix the english tabs and sorting, I can make a post on how to convert Sash\'s ROM into a purely english version with the SL5600 libsl. But it will be a long post...so lets see what happens.
