> Are you sure your kernel has CONFIG_CRYPTO_ARC4=y?

Indeed, the arc4 module is enabled as a module in the kernel but not 
deployed in my filesystem.

I added it and my error message is gone. I will test on several WiFi 
routers tonight.

Question:
How could I have know that this module is needed? I see not dependencies 
to the arc4 crypto. What did I miss?
I now needed to get deep into the source code to find the origin.
Are there any more crypto's I need for other routers?
