After checking the network details for your Slingbox it appears as though there needs to be some optimization done on the router that the Slingbox is connected to. This optimization is referred to as "port forwarding". Basically, port forwarding opens up a "pinhole" on your network just for the Slingbox and this allows it to connect to mobile devices, as well as "connected devices" (Roku, AppleTV, Chromecast, etc.) to the best of it's ability. For further information regarding port forwarding, check out these articles:
