As I understand, sometimes, while viewing the Slingbox from a remote location you loss the streaming. This can be caused by the network connections you are using or due to insufficient bandwidth on the Slingbox location.
Please, let us know how is your Slingbox connected to the router and which is the upload speed that you have at home.
We recommend you to be as specific as possible about the issue you are having. This way, other forum users will be able to help you with accurate information.
