I have had some complaints of the Amazon Fire TV Box not connecting to the internet when using the Ethernet cable rather than Wifi. The most common cause is that the Ethernet cable was connected after the Amazon Fire TV was powered on and the Wifi may be trying to connect. Here are a few suggestions on how to get the Amazon Fire TV Box to connect to the internet with the Ethernet.
Easiest First: Remove the Power Cable from the Amazon Fire TV Box. Connect the Ethernet cable to the Amazon Fire TV Box, and the other end to your router. Power the Amazon Fire TV Box back on. This will usually correct the issue of the Amazon Fire TV Box connecting to the internet over Ethernet.
If this does not work then...
You Can Also Check the Settings:
- Connect one end of an Ethernet cable to you Amazon Fire TV Box and the other end to your router.
- In the Amazon Screen go to Home screen, select Settings > System > Network > Wired. This Should select the wired network as you primary internet connection.
