About a month ago, when we changed our WiFi internet from spectrum to att. The roku, all of a sudden started disconnecting. We would re-synced or re-connected it but, it stayed doing that everyday. Until about a few weeks ago, we got another tv and moved the roku upstairs. The roku doesnt disconnect anymore, but now only volume and power button work on the remote, nothing else. How can I fix it or do I need to buy a new roku?
