Now, that you IP is updated there is only one thing left to do. You need to change numbers of DNS servers on your device.
On Roku and NowTV it might prove difficult as it does not allow such change. But don’t worry. With SmartDNS it is not a problem (Windows Phone device owners are in very similar situation) as long as there is a router on your Home Network.
Simply changeDNS server address on your internet access device and your Roku player will be able to benefit form SmartDNS service.
If you can’t find your router in this list here you can find our DNS servers and you can use our existing router tutorials as example for your router.
