When I watch slingbox on my PC I can bring up my home remote and it works fine changing channels. However, if I go to another room and use my laptop and connect via wifi, I can bring up slinbox but when I bring up my remote on screen I can't change channels. The only button that works on the remote is the mute button. Strange ??? Any explanation?
Hmmm, my initial thought is perhaps the wrong remote is configured? What type of Slingbox do you have? Might be worth it to re-configure/reset your Slingbox as an initial troubleshooting step. This article: How to reset your slingbox will walk you through the steps.
Let me know if you are able to try that.
