Thank you for the suggestion again, this really helped me isolate my problem!
Per your recommendation, I set up my Windows desktop as a PMS. I added the HDHomeRun and I was able to see Live TV from the Windows PMS. So this proved that the HDHomeRun itself was good and I had decent signal.
So what could be the difference with the Linux PMS?
To briefly explain my setup…my modem/router/switch/PMS server are in my basement. I have a single Ethernet cable running from the switch in my basement to a different router upstairs that’s been configured as an AP (bridge mode). Both my Windows desktop and the HDHomeRun are directly connected to the LAN ports on the AP. I’ve had the Ethernet cable from the basement connected to the WAN port on the AP…but that WAN port should act just like a LAN port, since it’s configured in bridge mode…right? I guess not so much…I moved the Ethernet port from the WAN port on the AP to one of the empty LAN ports and now I’m able to watch Live TV from the Linux PMS.
So I guess I’m confused what traffic might be being blocked when that Ethernet cable was connected to the WAN port on the AP. Maybe the AP is blocking some broadcast traffic, even in bridge mode. Is broadcast traffic somehow needed between the PMS and the HDHomeRun? I’m considering putting another one of these HDHomeRun devices at a relative’s home in another city (connected via VPN), so it would be good to understand the network connectivity requirements better.
