Select the "Use phone as remote" option located at the bottom of the screen. On Roku, go to Settings and select Network from the menu. Hit Set Up Connection and choose Wireless as your network type. Finally, connect to your desired wireless network and enter the Wi-Fi password if required. You are now connected!
