Well, come to find out the issue is a Logitech issue and is related to bugs in their ointment....
I just got off the phone with the CS Rep and he performed a few tweaks on his side that permitted the error associated with the activity button assignment to be resolved. The bugs, cause a few issues of which one is false positive that the hub is communicating with the wireless network. Additionally, assignments of activity buttons are throwing an error when applying changes. The CS Rep indicated a new firmware release will be coming in the near term to correct these issues.
So, for now its back up and running. If anyone encounters behavior that just doesn't add up, its likely the hub and network connectivity issue. Should that happen, the advise is to unplug the hub for 5 minutes then plug it back in. While I not only did that yesterday, I as well cycled my router of which did nothing to correct the problem. So it appears to be a crap shoot as looking at the wireless settings you cannot discern that the hub isn't communicating with the network as the led light stays green and the GUI display shows as connected.
