Hi superfine6999, lynn1960 & RDRKRNR,
For these type of network issues where you get blinking lights, I recommend to perform all the steps that you can find here,
This behavior can also be caused by faulty power supply, have you tried a different one?
Hope this helps
I had this problem too. The answer is that you need to plug your slingbox into an outlet that is NOT where you've plugged in any other electronics. Don't use an extension cord and don't plug it into the same power supply as your TV, cable box, DVD player, computer, or any other electronics. This is the only thing that worked for me.
