How to Fix Authentication Problem on Kindle Fire

Kindle was a brand name that started as an ebook reader. Then, as any brand is expected to evolve and expand over the years, Amazon went ahead and introduced the Kindle Fire tablet.

The Kindle Fire and Kindle Fire HD line of devices have gone on to be defined by their affordability and ease of use. For Prime members, it has become one of those important ways to connect to the Internet, shop on Amazon, and even read ebooks.

However, what will you do if your Amazon Fire tablet faces trouble connecting to the WiFi network? If you face the same problem, we are here to resolve your Wi-Fi-related issues with simple fixes and troubleshooting steps.

What might be Causing the Authentication problem – Kindle Fire

Your Kindle Fire device is based on Android, which has its own set of features and quirks. For example, sometimes, the authentication issue on Kindle devices arises due to issues with Wi-Fi settings, while in other instances, it could be your Wi-Fi network.

Kindle WiFi issues can be fixed pretty easily.

How to fix Wi Fi network authentication error on a Kindle Fire Device

Switch On and Off Airplane mode

To Switch on or off the Airplane mode:

  • Swipe down the Amazon Fire notification bar.
  • Tap on Wireless.
  • Tap on the Airplane Mode.
  • Toggle it On then Off.

Specific network issues can be fixed by doing this. If there’s no Airplane Mode option, check out other methods.

Connect to WiFi Network Again

Sometimes, some unidentifiable errors can also occur due to Go to your Kindle WiFi Settings

  • In your Kindle Fire, open the Settings menu.
  • Switch your Wi-Fi to On if it is not On already.
  • You will see a list of all the available networks.
  • Select your Wi-Fi.
  • Once you tap on it, you might be asked to re-enter the WiFi password depending on the network security type.
  • Enter the password and connect to WiFi.

This should resolve your WiFi issue.

Restart Your WiFi Router

So you did reconnect your WiFi and yet couldn’t resolve the Kindle Fire authentication problem? Did you try restarting your Wi-Fi Router?

This is easy. Switch On and Off your router or remove power from the electric outlet.

Reset WiFi Router

Resetting your WiFi Router can format it to its factory settings and help fix wireless authentication issues to connect to the Internet.

  • Most WiFi routers have a WPS or Reset Button placed near the LAN/WAN Ports.
  • If this button is not present, the Power button will serve the purpose of resetting your device.
  • It would help if you held down the Reset or Power button for a few seconds.
  • You can also refer to your router-specific manual to find the process to reset it.

However, do note that this will reset your router to its default configurations. Your password will be reset, and there is a slight chance that your Internet Service Provider’s settings might need reconfiguration.

Remove WiFi network

Now and then, you end up having too many routers saved on your Kindle device. This is not ideal. If one of your Wireless Access points is renamed or its authentication key is changed, the old one could stay in your saved WiFi network list while the new SSID name is added as a different entry. To remove extra entries, go to:

  • Settings > WiFi > Switch on Wifi
  • Tap ‘Delete Saved WiFi Passwords’

After, this, you might need to reconnect to WiFi and enter the wireless authentication key or password again.

How to Fix Server Authentication Problem – Kindle Fire

Until now, we have covered the basic issues with the Amazon Kindle Fire and ways to fix them. However, there are certainly other forms of issues that need different remedies.

If you have been facing a Kindle Fire authentication problem that is yet to be resolved, you can try the following methods:

Reset the Time and Date of Your Kindle Fire

Whenever you connect to the Internet, the Time and Date of your device are synced. This happens only when you have ‘Automatic Time Zone’ enabled. Sometimes, if the time on an Android device is not synced or updated correctly, many apps, including Social Media, Instant Messaging, Tools, and Shopping fail to connect to their server.

One of those methods is to ensure that the time and date of your device reflect the actual time and date.

  • Go to Settings > Device Options > Date and Time
  • Click on Time > Set Time Zone
  • Select your Time Zone
  • You can check whether the device time is correctly updated in the status bar.
  • You can also Enable and Disable the Automatic Time Zone in the Date and Time Menu to see what works.

Once done, restart your device and try and check your favorite apps and websites: your authentication failed issues should be resolved!

Update Your Kindle Firmware

Yes, we know those software update reminders can sometimes seem too much. However, considering that most software updates are tailored to fix bugs and enhance features, it’s always a good idea to be on the latest firmware.

  • Go to Settings > Device Options > System Updates
  • You will see whether you already have a Software update ready to install. If not, tap Check now.
  • Your Kindle device will then check for updates and might restart during the process.

Reset Kindle Fire

Now that you have tried all possible solutions for the Kindle Fire authentication problem when connecting to the Internet, it is time to bring out the final option: a factory reset of your Kindle device. To factory reset your device,

  • Open the Settings app from your home screen.
  • Go to Settings > Device Options > Reset to Factory Defaults
  • Tap Erase Everything

This will restart and set your Kindle Fire device to its Factory Settings, thereby resolving any usual glitches with the system.

Get Help for Your Kindle

If none of the above resolutions works for you, there is one option left: Kindle Help. You can go to your Amazon account and contact the customer care service to either get your Kindle File Device fixed, or replaced.
