Sorry,

but I have learned. A secoung installation brought the missed file.

Now there are the problems of WLAN:
all drivers seams to be loaded. After unloading and loading

iwlist eth2 scan

works well, but there is no possibility to enter frequency or channel or essid via

iwconfig eth2 essid "...." channel "..."

In the manual was written, that most of the time this error occurs if installation is wrong....

Compilation of ipw2100 is not possible while the some files are missing. Where can I get them? Which files are neccessary?

The connection to the AccessPoint via line works. Nice.

Thanks
