@khabib0460, I assume you have a Roku device you're trying to connect to a TV and not an actual "Roku TV". Some Roku devices only support 2.4GHz Wi-Fi and Xfinity has a habit of disabling it in their customers' routers. What's the model number of your Roku device displayed under Settings->System->About and what exactly happens when you try to connect to Wi-Fi? Does your network show up when it scans for networks?
