The wireless connection state is not known unless you go to Settings->Network. The point is, that if you click a channel, the box should tell the user that his Roku is not connected. Instead of him going into a channel and then he could wander around for awhile until he tries to access the network and then it just hangs. If the Roku kernel wont tell the user, why not provide a method or state that some brightscript code can detect it ?
On the "retrieving" display, I said "springboard", it should have been a PosterScreen. If I set the SetListNames() for the filter banner and then SetContentList() with one of the objects being invalid. The display shows retrieving but there is nothing to retrieve.
