You need a remote, period! Just get a cheap universal remote that supports your brand of TV just to get through the Wi-Fi setup and then you can go back to using the app. The only other option is to set up your new Wi-Fi with the same SSID and password on the same band (2.4GHz vz 5GHz) as you old Wi-Fi.
