I tried using wifi-radar as suggested but it has the same problem.  If my ssid on the wireless router is not broadcasting, I can specify an essid in the wifi-radar profile but when I click connect, it cannot acquire an IP address.  If I then turn on the broadcast, the interface configures itself normally.  Something must have changed between 6.10 and 7.04 in regards to the wireless' ability to connect to APs that are not broadcasting.  Any other ideas?  Should I submit this as a possible bug?
