Why Does Amazon Fire Say Authentication Problem?(+Solutions)

The Amazon Fire TV brand has been around for a couple of years, yet not everybody is entirely familiar with it. It comes in many forms varying from USB sticks to portable boxes. The Fire TV brand can be thought of as a family of devices that allow your television devices to stream online content.

Why does Amazon Fire TV say there is an authentication problem? It happens because there is an issue with the Wi-Fi connection or there are too many routers connected to the same channel. Sometimes users input the password and not the authentication key. The problem can usually be resolved by fidgeting with the home router and the Wi-Fi settings on the device. 

However, this is pretty different from what Amazon calls “Kindle Fire.” Kindle Fire is a line of Wi-Fi-enabled Kindle devices launched way back in 2011.

Reasons Why Amazon Fire Says There Is an Authentication Problem

It is pretty common for newer and older Kindle Fire devices to run into authentication problems; however, you do not need to worry about such a problem. There are simple fixes available for it. To understand the fixes, we must first locate the cause of the problem.

The main reason why the authentication problem arises is due to an issue with the Wi-Fi connection.

The problem can usually be resolved by fidgeting with the home router and the Wi-Fi settings on the device.

This means that the cause is the device’s inability to recognize a network.

All Kindle devices need access to the internet via a Wi-Fi network to provide you with all of its services; therefore, having this issue will constantly force the Kindle to display the pop-up authentication error box.

Downloaded content would still be accessible since that is the USP (unique selling point) of the Kindle. Even then, it is advisable to fix this issue as soon as possible to avoid any further inconvenience.

Try reconnecting to the Wi-Fi 

Router: Sometimes, the router may be causing the issue. It requires a simple restart to start functioning again. Follow the steps below to carry out this fix.

Unplug your router from the socket. Do not plug it back in for a few minutes. Let it rest for a while.

  1. Plug it back in after a few minutes.
  2. Make sure to restart your Kindle too. Long press the power button to do this.
  3. Now go to the Wi-Fi settings and forget your network.
  4. Click on your network again to re-enter its password and finish setting up a fresh connection.

This is a comprehensive fix that is capable of fixing other problems with the Kindle, too (not just the authentication error).

Set Time/Date

Check that the time/date/Time Zone is correct on your device. In some cases, it helps to solve the issue.

Reset the Router

Resetting the router could fix the issue. Reset your router to its factory settings via the instructions given on its original boxes. Some traditional routers have a reset button on them or come with a disk.

Others can be accessed via the router’s IP address when it is typed into the browser. Look at your router’s instructions manual for proper directions.

Clear the cache
