The V3 hub will work initially with cameras (streaming) while connected via WiFi. After the hub sits for 30 or so minutes and you try to stream from a camera, it will stay loading for some time and then go back to the camera selection screen. iOS and Web. If I plug the ethernet cable back in, the cameras will start working again. While the camera's aren't working, it will eventually come up and say the cameras aren't connected and contact support. They come back online shortly after plugging the ethernet cable back in. If I wait and unplug the ethernet cable again, the cameras will still work until around 30 minute and they go unresponsive again until the ethernet is back in.
