Fire TV Cube Ethernet Not Working – Possible Causes and Fixes

Have you tried to use your Fire TV Cube ethernet connection, but it isn’t working? If so, there are a couple of things that you should do to try to fix this. Here are some troubleshooting tips for common issues with the ethernet port on Amazon’s newest streaming device.

First Things First, Restart Your Fire TV

Although it seems like a relatively easy fix, restarting your Fire TV Cube is one of the first troubleshooting tips that you should try when figuring out why your ethernet port isn’t working. It’s also a good idea to unplug it from the wall socket for a few seconds, then plug it back in.

Most people forget this step and end up having to do a factory reset or even return their device because they assume there’s something wrong with it.

Did this work? Move to the next tip if restarting your Fire TV Cube didn’t work to fix the issue.

Restart Your Modem or Router

Sometimes the issue isn’t actually with the device itself, but the router it’s connected to. Therefore, try restarting your modem or router before you try anything that may undo your settings or change the device’s performance.

To do this:

• Unplug the Fire TV from the wall.
• Unplug the modem or router from the wall and wait at least 30 seconds.
• After 30 seconds are up, plug the modem back in. If you also have a router, plug it in once the modem is up and running.
• Plug the Fire TV once the modem and router are working.
• Try connecting the Fire TV Cube ethernet cable.

Check Your Modem/Router Settings

Incompatible settings between your Fire TV and router could be the cause of ethernet connectivity problems.

To fix this, try changing some settings on both devices to make sure they are compatible. But first, check if the settings need any changes. They should look as follows:

2.4GHz network

If you’re using a 2.4GHz network:

• Select a network channel between channels 1-11.
• Ensure the broadcast signal of the router is either B, G or N. The Fire TV will not support other signals.

5GHz network

If you’re using a 5GHz:

• Select a network channel between channels 36-48 or 149-165.
• Ensure the broadcast signal of the router is either A or N. The Fire TV will not support other signals.

2.4GHz and 5GHz networks

For 2.4GHz and 5GHz networks:

• Try changing the network security to ‘Open’.
• Change the radio mode of your router to g/n only.
• Update the firmware.
• Ensure you have not reached the maximum number of network connections (11 for 2.4GHz, and 23 for 5GHz).

Firmware Update

Another possible cause for Fire TV not connecting to the internet is a missing firmware update. Updating the firmware will not only remove bugs but also add new features and improve system performance. To check for available updates:

Settings > My Fire TV > About > Check for System Updates

Factory Reset Your Fire TV

If none of the above works, you might need to factory reset your Fire TV. This deletes all data stored on the device, so it is advisable to do this as a final measure. To reset your Fire TV:

• Hold the ‘Back’ and ‘Right’ navigation buttons for 10 seconds.
• Select ‘Continue’ or wait several seconds for the Fire TV to automatically reset.
