WDTVLive loses connection to slingbox, cannot access connection speed test

WD Legacy Products WD TV Live Streaming

I have a Slingbox 500. I have the same problem. Is WD working on this issue? I don’t see a resolution or comment from WD in the forum.  This problem arose after I updated the WDTV firmware. Can I get the older firmware back? I haven’t yet posted a review of this product on Amazon but if no answer is forthcoming I will give it one star.  My router has the Slingbox on a static IP. I am forwarding ports 5201 and 5001 for both UDP and TCP. My Slingbox is in a DMZ zone. I note many complaints on the nternet but no other solutions other than the above
