Roku does not allow you to change the DNS settings so you will have to change the DNS settings on your network router.
After you have added the SmartDNS to your router then you can continue setting up your Roku device. This is important because the Roku device will determine the country of the channel store during setup.
Step 1
If you have previously linked your Roku your first step will be to unlink it. To do that go to https://owner.roku.com/Login, scroll down and click unlink.
Step 2
Now configure the DNS settings on your network router. If you have a router that’s not on the list, feel free to contact our support, give us the make and model of your router, and we’ll help you figure out whether or not you can add custom DNS servers to the router.
Step 3
Create a new Roku account. Do that by visiting owner.roku.com and register for a new account, using a different email address than before (that is if you have previously registered your device).
Step 4
When registering a billing address you need to select United States and a valid billing address. For ex:
58 Middle Point Rd
San Francisco, California(CA), 94124
Step 5
Once you have created a Roku account reset your Roku device. The best way to do that is by using a paper clip, pressing and holding the reset button on the back of the device for about 20-25 seconds or until you see the Roku welcome screen
Step 6
Link your Roku device. Connect your Roku device to your network router which should be connected though Smart DNS servers by now.
Step 7
Go to https://owner.roku.com/link to link your Roku device to our newly created account.
You’re done! Here you will find what sites and media channels are unlocked via SmartDNS.
