The slingboxHD pro has been working beautifully for quite some time, both through local network and internet viewing. Now, the computer and internet sees the slingbox but there is not picture or sound. My iphone said the signal was weak. The upside-down U shape of red lights keeps the lights rotating while trying to view on computer but never locks in. Is it broken or is there a reset? I have unplugged router, slingbox, cable box. All of no avail.
I understand that you are having some issues with your Slingbox PRO HD, since you are not able to get it up and running.
As the first step, I recommend you to reset the Slingbox and then run the Setup Assistant for Internet Viewing. The following links will provide you with the steps to follow.
