The Fire TV Cube combines a streaming box with a hands-free Alexa speaker. It has a faster processor than the Fire TV Sticks, and the latest model has a built-in Ethernet port — both of which help a VPN run smoothly.
Setup takes a few minutes. Here's how.
- The Fire TV Cube runs Fire OS and installs VPN apps from the Amazon Appstore.
- The current (3rd-gen) Cube has a built-in Ethernet port — use it for the most stable VPN speeds.
- Alexa voice commands keep working while the VPN is connected.
- Use a nearby server to keep 4K streams smooth.
Why the Cube is a good VPN device
- More processing power handles encryption more easily than budget sticks.
- Built-in Ethernet on the 3rd-generation Cube gives a stable wired connection. Older Cubes can use Amazon's Ethernet adapter.
- More memory means fewer slowdowns when switching apps.

Step-by-step setup
- Check your software: Settings → My Fire TV → About. See how to check your version.
- Install the VPN app from the Appstore. You can also send it from the Amazon listing using Deliver to → your Fire TV Cube.
- Open the app and activate it. For our app, enter your lifetime activation code under Settings or Activation — full steps on the How to Use page.
- Select a nearby server and connect, then approve the VPN connection request.
- Run a quick leak test to confirm it's working.
Using Alexa with a VPN
Alexa keeps working while the VPN is connected. You can say "Alexa, open [app name]" to launch the VPN app hands-free, then connect with the remote.
Some Alexa features use your location, so if you connect to a distant server, things like local weather might look odd. Connecting to a server in your own region avoids that.
