My autoscanner died on the 22nd... I pulled up the "Connected Devices" tab on my router & was somewhat confused when my HD HomeRun didn't show up. Power-cycled it -- it appeared in the list but still didn't scan -- took another look & it had disappeared from the router again. Right-hand LED would go out, then the left-hand would go out, then the left-hand would go red, then it would blink a few times & go green again.
To make a longer story short, the HD Homerun was in a reboot loop.
See this post on the HD HomeRun support forum:
- Download the newest HomeRun firmware.
- Install the download on your PC.
- Disconnect the WAN port on your router so the HomeRun can't find the Internet.
- Run the download. It'll find your HomeRun and automatically load the current firmware.
- Reconnect your WAN port.
The instructions say to disconnect the WAN first, then install the download. I had to do it in the other order -- it wanted to install Microsoft C++ Redistributable, and failed with Error 12007 because it couldn't find the Internet.
I'm not sure whether it's the firmware update or the fact I bought a new router, but I can now stream HD channels to my phone or tablet. Before the upgrade HD channels would pixelate badly and eventually freeze.
