Sorry to hear you’re experiencing issues. Has the H9000R ever appeared in Emote? (in other words, is this an intermittent issue or a more prolonged one?)
It would be helpful to know more details about your network setup, as the issue may be in the configuration. In addition to the network connection between your H9000 and your computer, the Recovery mode also requires an internet connection to your H9000 (unless you are using a USB Recovery installer).
