Setting up a wireless network with no password?

[brennen]

Migrated from @zomerfeld's issue on Adafruit-Occidentalis:

Any advice?

Setting it up with a blank password doesn't return errors but the system remains offline.

occi, the utility that handles this, lives in this repo now. I'll have a look at some point. (Though my primary advice would be "probably don't do that". :) )
