Difficulty Level: Advanced.
Just a small heads up that this process is a little complex so please read the entire process first to make sure you are capable of completing all steps.
The issue with using Netflix outside of the US is that the software checks your location and blocks the playing of content, to work around this you can use a proxy server, a VPN service or even some DNS solutions will allow you to get around this and play content from your PC or android device. Chromecast however is a little more tricky as it always uses the google DNS servers 18.104.22.168 and 22.214.171.124 and you cannot configure it to use a proxy or VPN. It would be possible to have your router always connected to a VPN service but this would mean all traffic would go via the states and also not many modems support this functionality.
- A Netflix US account. To sign up use a free VPN or proxy service as the signup is also location locked. If you do not have an account yet you can signup after you have configured your modem in Part 2.
- A free beta account from https://unlocator.com/
- An android based phone or tablet, according to Google Play Android version 2.2 upwards is supported for the Netflix 3 app. If you are using iOS then you will need to figure out how to get the app onto your device yourself.
- A router (modem) which supports dd-wrt firmware. Check http://www.dd-wrt.com/site/support/router-database to ensure your modem suits. My orcon modem didn’t so I had to add a second router to my network as an Access Point (AP mode) to use so this shows as a second wireless network at home. If your modem does not support the dd-wrt firmware then you may be lucky and there may be another method for your modem, check here.
- A Google Chromecast Dongle
Process Part 1: The Netflix App
Lets start with the easy part first, getting the Netflix app. If you are in New Zealand you will not be able to install directly from google play as it is location locked so you need to download the APK file and install it manually.From your device either visit this site http://goo.gl/clUkzq or scan the QR code below and download the apk file. In order to install it you will need to allow ‘Unknown Sources’ to install apps, enable this in your phone settings under the ‘Security’ menu.
As I mentioned earlier your router needs to support the dd-wrt firmware and you need to upgrade to this firmware. To do so go to the website (link above) and download the firmware for your exact router model and install it from the routers web administration console. Once this is done you need to configure the modem for your LAN again, then enable WIFI and WIFI security. Once that is done follow the guide here to configure your modem to use the Unlocator service. Once the modem is configured do a reboot of it then connect your Phone/Tablet to its WIFI and boot up your chromecast (they need to be configured to use DHCP). You will need to configure your chromecast to also use this WIFI, this can easily be done from your Android device too by installing this app.
Once you have all devices using your newly setup router you can launch Netflix on your Phone/Tablet and sending it to your Chromecast should work.
