I'm using RobertCNelson's 4.1.10-bone16 kernel in an embedded application where I use a PHP script to configure /etc/network/interfaces to allow connection to a wi-fi network. Worked *perfectly* until I encountered an open network (no password required). I've since replicated the failure on a wide range of open networks, including when I change a working router from WPA to 'none'. I would really like to be able to connect to open networks. We have no control over the networks that we encounter - just this week at a trade show, for instance.
