Try choosing "Shared Key" auth mode in the connection editor.
Right-click on the wifi icon in the menu bar, choose "Edit connections".
Click the "Wireless" tab, adn double-click your adhoc connection.  On
the wireless security page, choose "Shared Key" auth method, then hit OK
everywhere and try the connection again.

I'm somewhat dubious that Shared Key is actually legal with adhoc, so it
may just be driver problems too.
