Whether you're using a standalone TP-Link router or managing a complex network of smart devices and IP cameras from Trimatrik Multimedia, firmware updates help ensure every connection is safe and optimized.

How Often Should You Update Your Router Firmware?

You should check for firmware updates for your TP-Link router at least once every three months. However, when critical security vulnerabilities are discovered, like the recent CVE-2024-21833 and CVE-2024-5035, you should update immediately.

Set a recurring reminder to:

A few newer models from TP-Link, such as the Deco and Tether apps, can automatically update, notifying the user of an update or updating during non-congested hours. 

So, I trust that you are aware of the importance of having the most up-to-date firmware on your TP-Link router to ensure that your network is secure. Now, let's get you prepared for the update process. In the next section, "Pre-Update Checklist: What You Need Before Starting Firmware Update," you will find guidance in regard to what needs to be prepared immediately before initiating the firmware update so that everything goes as planned / smoothly. 

Pre-Update Checklist: What You Need Before Starting Firmware Update

Now that we know updating the firmware of your TP-Link router is important to security, I want to make sure that you are correctly and efficiently prepared for the update process. If you follow the checklist, you will not run into problems and hopefully have a smooth experience updating firmware on your options with TP-Link.

A. Checking your current firmware version

Before you download updates, you should know the current version of firmware for your router. This is typically available on your router's web management page. Go to your router's admin console and find the system info or status page. The installed firmware version will be noted so that you can compare it with the most recent available on TP-Link's website. This is important in determining whether an update is required.

B. Finding the model and hardware version of your router

This is arguably the most vital step to follow prior to upgrading. Obtaining the correct model and hardware version of your TP-Link router is absolutely indispensable in order to avoid potential damage to your device. Installing firmware for a different hardware version can potentially damage your router or void your warranty. The hardware version is usually also printed on the label at the bottom or rear of your router, along with the model number. Take great care to copy both pieces of information verbatim, as you will use them to download the proper firmware file from TP-Link's website.

C. Having a wired connection to your router that is rock-stable

Among the most essential safety precautions while the router firmware is undergoing update is to have a wired connection of good quality between your computer and the router. The instructions explicitly caution against wireless updates for firmware. A wired Ethernet provides much less likelihood of being broken in the middle of the update process, which could leave your router unusable. Before you begin, connect your computer directly to one of the router's LAN ports using an Ethernet cable.

D. Backing up your current router configuration

Some firmware updates have the unfortunate effect of resetting your router and wiping all of your customizations from the settings, including your Wi-Fi network name, password, and other specific details you have altered. The best course of action is to spend a few minutes making sure to back up the configuration of your currently functioning router so that you do not need to reset all the settings manually if you get unlucky with an update. 

Many TP-Link routers will have a Backup option in the web interface that allows you to save your current configuration as a file on your computer. If the update on your TP-Link router happens to reset the device, you will be able to restore to your backed-up configuration. 

With this complete, you are now very much ready to move on to the main router firmware update process. Now it is time to move forward with the detailed, step-by-step process for updating your TP-Link router firmware, regardless of whether the model you have can take advantage of a TP-Link Cloud automatic update or whether your model must be updated manually via a downloaded firmware file.

Remember that regardless of which method you choose, maintaining a stable power and internet connection throughout the update process is critical to prevent potential damage to your router.

Conclusion

Updating the firmware of your TP-Link router regularly is an important step in securing your network and ensuring it is functioning as it should. By following the steps in this post and taking careful notes out of respect for your time. You'll already know how to locate your hardware version for your device, accurately download the correct firmware file, and safely execute the firmware update.

Always be cautious: if you install the incorrect firmware, you can cause irrevocable damage to your hardware and may even void your warranty! So, be sure to confirm the model of your router and its hardware version before executing any updates.

Your network security is only as strong as its weakest link! An additional weak link is having the firmware outdated, exposing your system to vulnerabilities that cyber criminals thrive on. If at a minimum, make it routine to check for firmware updates approximately every few months.

If you encounter problems throughout the firmware install process, TP-Link has the resources available for support in troubleshooting steps. The update is a security measure, but firmware updates can also bring better connections, improved performance, and, every once in a while, new features to enhance your internet experience.
