Has anyone been experiencing problems with Live Channels, Nvidia Shield and HD Homerun the last few days? Suddenly my Shields are sometimes unable to find my HDhomeruns. One is wired and the other is wireless. I don't have this problem with my Miboxes or using Kodi to watch Live TV.
I've got the 2015 SHIELD Pro, fully updated on the latest firmware and all relevant apps kept up to date (Live Channels, HDHomerun Beta, etc.) and no network discovery problems here either. Maybe you ought to just try and clear the Live Channels app cache and Live Channels app data, uninstall, then reinstall. Sometimes it's the easiest of things giving us fits and we don't realize it.
