Thanks for posting to our Forums!, I'm sorry to hear that the Slingbox you have keeps disconnecting
I do see here that you have a Slingbox 500. Now I have a few questions for you to help me get your Slingbox to stop disconnecting. Is your Slingbox setup for a WiFi connection or a Hardwired connection? If WiFi connection how is the signal strength on the Slingbox? Have you tried to do a complete factory Reset to your Slingbox?
If you have not done a factory reset I would try that first. Below is an article that will assist you in preforming a Factory reset.
Hope this helps!
