Hello! My Roku Express Remote has not been working plus my Roku TV Remote in another room hasn't worked in a while. My family has used the downloaded ROKU App to access streaming however we needed a new router for our internet so now the Roku Express and Roku TV are not on the correct wifi to access streaming. Since the remotes don't work we can fix settings and the app won't connect to the Roku Express or TV because they are on the old network that doesn't exist. Would it be recommended to buy new a Roku TV remote and nee Roku Express? Please advise.
