I see all my program from my car anywhere. But my installation of internet viewing is not correct.
If connect to the Slingbox from your Car using a computer or a mobile and it's not connected wireless or hardwired to the same router where the Slingbox is, that's called Internet Viewing. So you need to check the network settings at the remote location or at the place where you have issues connecting to the Slingbox,
If you cannot connect to the Slingbox just from one computer or a location, it will be necessary to check the security/firewall settings
