Just recently upgraded my Comcast X1 technology.. Have not been able to re-hook up my Slingbox 500 with the new router. One of the issues I'm running into is getting to the settings area on my television. The remote control for the Slingbox 500 has the upside down U symbol. My remote control on the bottom of the symbol has a blue light instead of the red light. What is the remote control trying to tell me. I'm presently trying to use ethernet connection but I can't access Slingbox set up. It goes to gallery but not the physical set up.
