My remote has recently broken and while trying to troubleshoot the remote, the streaming stick became disconnected from the wifi so I can't connect to it through the app. What can I do at this point as I currently can't watch any tv?
There's no way to enter the Wi-Fi configuration on a stick without a genuine Roku remote. If you simply restarted the stick then the Wi-Fi settings should still be intact. It should be searching for your network. If you did a factory reset or "network connection reset", then you're out of luck without a Roku remote. Sorry.
Try Amazon Remotes are pretty cheap. Just make sure you get the right one.
