I think the problem is with your system (maybe the router?) and not the Slingboxes. I have had 2 Slingboxes connected to a Verizon FIOS system for over 3 years and I have never had to reset either of them. Doesn't help you, of course, but I wouldn't concentrate your troubleshooting on the Slingboxes, particularly if it happens with both of them, you need to look elsewhere for a single point in the netwrok they both use.
Do you use a TCP or UDP connection or both? Since my problem is with both local and remote network connections, and since I can successfully ping the malfunctioning Slingbox before resetting it, I can't see its being a router problem unless it is a bug with how the Slingbox firmware handles the router streaming. Also, resetting the router does not cure the problem, only resetting the Slingbox. Thanks for your response, though. This goes to the bigger issue that Slingbox.com has lousy technical support. If they had a first-rate operation, they would help. How about a way to a reset the Slingbox remotely?
This seems to be a general problem with all (?) Slingboxes using the Web-based Slingplayer. Things periodically stop working without any obvious reason, and the only way you can right things is to do a hard reset of the Slingbox. If you are away from home, you are out of luck until you get back home. The whole system can't do what it specifically was designed to do. Compounding this basic problem is the fact that there is virtually no customer support if your Slingbox is out of warranty other than writing a note on this community chat and hope that someone has some good advice.
Can you help? My system: two Slingboxes HD Pro connected directly to a very fast Verizon FIOS router with separate static wired connections and port forwarding. When things are working, each Slingbox connects at 40 Mbps or better, both locally and remotely. Everything works well. Then things stop working, with either one or both Slingboxes, remotely and locally. "Network Error". Hard reset time. I have tested the router connection to the malfunctioning Slingbox and can ping the Slingbox successfully. This leads me to believe that there are serious bugs in the Slingbox firmware (updated, of course). Does anyone have a better explanation? Better yet, is there a fix? Do others have this same problem? Is it a problem with all Slingboxes, as it seems to be from reading other posts?
