Hi TechGuru99,
That's a common frustration! The scanning process can be quite sensitive. Let's try a few things:
1. Antenna Placement: How far is your antenna from the tuner? Ensure it's within a reasonable range and not obstructed by metal objects or thick walls. Try repositioning the antenna, even slightly, and rescan.
2. Network Connection: Is the HDHomeRun directly connected to your router via Ethernet? Wi-Fi can sometimes introduce latency or packet loss that affects scanning.
3. HDHomeRun IP Address: Make sure Plex is configured with the correct IP address of your HDHomeRun. You can usually find this in your router's connected devices list or by using the HDHomeRun network setup tool.
4. Channel Scan Settings: In Plex, when you set up the tuner, did you specify a region or zip code? This helps Plex narrow down the frequencies to scan. Sometimes, a manual scan for specific frequencies can be more effective if the automatic one fails.
Also, double-check the HDHomeRun's own status page (usually accessible via its IP address in a web browser) to ensure it's detecting the tuner and any connected cables correctly.
