I should have mentioned that I don't seem to be able to connect to unencrypted networks either. Just tried today at a local hotspot and while getting very good signal readings in Fedora Rawhide (and confirmed later in Vista), I couldn't connect to the network. Unencrypted network connection negotiation takes longer than protected networks, and both take a LONG time (1+ minute negotiation) before stating that the connection couldn't be stablished, or prompting for the Network passphrase/security token.
