Comment 2 for bug 515045

I just checked into this; it isn't a bug, it's operator error. However, I didn't know that without reading the code, so it's unlikely that anyone else would either. The correct usage in this case is

wicd-cli -c --wireless --network 0

where 0 is the number of the network you wish to connect to. Try that and let me know if it works. I'm going to work on updating/creating the documentation for wicd-cli.
