I had the same problem as you when I changed internet service providers. Solid network light, but couldn't find the Sling Box on the network.
I just got off the phone with a Sling Box tech, and the problem is fixed. It cost me $29.99 for the call - which I think is ridiculous - so I'm going to share the solution with you for free. I hope it works for you.
Here's all we did...
Reset the Sling Box. That's it. Here's how you do it.
Unplug your internet router for 5 seconds, then plug it back in and wait for the lights to light back up (on your router)
Go to your Sling Box and find the small red red RESET button (on the back right side on my Sling Box Pro HD)
Hold down the reset button for 20 seconds, and keep holding it down
Unplug the power cord from the back of the Sling Box while keeping the reset button pressed
Keep the reset button pressed for another 20 seconds, then release
That did it. I had to go through the setup process again, but all works fine now.
One helpful note... when you go through the set up, after naming your slingbox, it will ask you to create a user ID. If you already have one, scroll down and click "login" to enter your current login info.
That's it. Hope it works for you!
Thanks, Scottie. That's so cool that you came here - I presume to share with the forum the solution you helped me out with today. I'm not surprised, since you were incredibily professional, informative and helpful this morning - it makes sense that you would come here to provide info that would help others.
I really appreciate your help this morning. You were so clear on what my "free" options were, and before I paid the $29.99, you made sure I understood what it covered and what it didn't. I presume much of that is scripted for all agents to follow, but there was something in your delivery and tone throughout the call that made me feel you really wanted to make it good experience for me - you weren't just reading a script.
I have no problem paying $29.99 for the service you provided. I should have added to my comment that the $29.99 was well worth it for the service you provided. It just sucks that this simple solution wasn't something I was able to find in the forums. This isn't my first time dealing with tech product troubleshooting, so I'm a but embarrased that I didn't think of the "red reset button" option this time. But thanks for helping me out, and for being so professional about it.
btw, if you're ever looking for another job in tech customer care, let me know. I know some people who would be lucky to have you on their team.
Sorry to hear about having to pay that much! I'm so grateful that you posted that information but unfortunately it didn't work for me. I reset my router and slingbox as you described and both lights came on solid once more and yet still when I try to go through the set up process, it can't find my slingbox. I can't understand it for the life of me! Grrr!
I guess I'm going to have to pay $29.99 too.
Thanks for posting though! I appreciate it!
