I am a student living in a college dorm, so I am at the mercy of the campus-wide wifi. Recently we had a big incident where the internet went down across campus for a couple days. I'm not sure if it's related, but ever since my roku will say the connection is excellent, but it is running extremely slow and will not load any of my apps. I am not having internet issues on any of my other devices. Is there anything I can try to get it to work?
