Troubleshooting communication errors

You might be asking why “only the HDHomeRun app isn't working”, when your other internet streaming video apps appear to be fine. Over-the-air TV signals tend to be a lot more demanding for network bandwidth, and sensitive to network connection issues, compared to internet streaming services. Internet streaming services fully control their video streams, and can adapt them to drops in connections, different speeds, and can use more efficient video compression. Broadcast TV uses standards that were designed for over-the-air transmissions, with many transmissions still using older standards made back in the 1990s.

This doesn't make broadcast video impossible, and most customers won't even notice a difference, but it is important to note that broadcast video is very different from internet streaming services.

Sometimes the issue is as simple as trying a different ethernet cable between the HDHomeRun and your router (or network switch). You will also want to try using a different ethernet port on the router, as it is possible for specific ports on a router to develop issues.
