A few months ago, the remote that came with my roku 3 stopped working. Instead of replacing it I just used the remote app. Last week I moved to a new apartment with a new modem, and now the app doesn't work because it's a different network. If I try to connect manually, it tells me I need my "roku device's IP address." No idea how to get that. It is apparently not the same as my actual IP address, which I tried using and failed. Anyone know how to get around this?
