How to find Roku IP address without remote or WiFi
Without a network connection, your Roku doesn't have an IP address. They are dynamically assigned by your router to devices that connect to your network. You can't enter a static IP in a Roku device.
And if you can't connect your Roku to a network without a remote, there's no way to control it. If you have a Roku Stick, you have to have a Roku remote, no other option exists. If it's a standard Roku player, they all support IR, so you could get an inexpensive generic remote from many stores. Just make sure it lists Roku as a supported device, as they all have specific IR codes they use.
If it's a Roku that you can connect with a wired network connection, then you could use a Roku app on a smart phone or tablet. After you connect the Ethernet cable, it will auto-connect to the network and you should see it on the app.
