Glad you figured this out. Can you provide more details as to why you were having the problem?
We will update the sample to throw a friendly error when not connected to a network. That should help avoid any lengthy troubleshooting problems in the future.
The wireless network I was connected to wasn't functioning properly. More of a network/user error than ESRI error, but you could provide a "user-friendly 404 error message". I would treat it as a very low priority IMO.
