Thanks for using our Answers forum. Sitting by the pool watching your Slingbox sounds great to me, I would love it to. I have an article, Items that you need to begin watching your TV with a Slingbox that should help explain the setup that you will need to do this. Another article that could have some useful information for you would be, Viewing your Slingbox over the internet.
Hope these help.

Hey...why not use a Slinglink? http://www.slingbox.com/go/slt
You plug the SlingCatcher into the Slinglink and connect it directly to the power supply (into a wall socket- not in a power block). The Slinglinks need to be on the same electrical circuit but if they are then plug the other Slinglink into a power socket near the router.
You plug the router into the other Slinglink that is indoors. They use your electrical wiring to send the internet feed.
Hope that helps!
