I'm trying to implement a wireless access point using Bering but haven't
been able to run it successfully yet. I can see the access point from an
external laptop but can't connect to it.

>From what I can see, I think there is an error with the WPA key, but I'm not
really sure. If anyone can make some sense out of the debug message I'd
really appreciate it if you could tell me how I can go ahead from here.

Many Thanks
