Download the latest firmware file from the D-Link website.

Click on the Firmware tab and select the firmware file that matches your device. Save the file to your computer and remember its location.
Open your router's web interface and log in. You can access your router's web interface by opening a web browser and typing [21](http://192.168.0.1) in the address bar. This is the default IP address of your router. If you have changed it, use the new IP address instead. You will be prompted to enter your username and password. The default username is admin and the default password is blank (leave it empty). If you have changed them, use the new username and password instead.
Go to Manual Settings > Maintenance > Firmware Update. This is where you can upload the firmware file to your router and start the update process. You may need to enter your username and password again to access this page.
Browse and select the firmware file you downloaded. Click on the Browse button and navigate to the location where you saved the firmware file on your computer. Select the file and click on Open.
Click on Upload to start the firmware update process. A progress bar will appear on the screen, indicating the status of the update. Do not turn off or unplug your router or computer during this process, as this may cause damage to your device or corrupt the firmware.

Benefits of Firmware Update
Updating the firmware of your router can bring you several benefits, such as:
Improved performance, stability, and security. Firmware updates can fix bugs, errors, or vulnerabilities that may affect your router's performance, stability, or security. They can also optimize your router's speed, range, or compatibility with other devices or networks.
New functions and features. Firmware updates can add new functions and features to your router, such as parental controls, guest network, VPN, QoS, or IPv6 support. They can also enhance or modify existing functions and features to suit your needs or preferences.
Common Issues with Firmware Update
Although firmware updates are generally safe and beneficial, they may also cause some issues or problems, such as:
Power interruption during the update process. If your router or computer loses power or shuts down unexpectedly during the update process, this may interrupt or abort the update and cause damage to your device or corrupt the firmware. To prevent this, make sure that your router and computer are plugged into a reliable power source and have enough battery life.
Communication error between the device and the source of the update. If your router or computer loses connection or communication with each other or with the internet during the update process, this may also interrupt or abort the update and cause damage to your device or corrupt the firmware. To prevent this, make sure that your router and computer are connected via a stable Ethernet cable or wireless network, and that there is no interference or obstruction in the signal.
Firmware file corruption or incompatibility. If the firmware file you downloaded is corrupted, incomplete, or incompatible with your device model or hardware revision, this may also cause problems with the update process or result in a failed update. To prevent this, make sure that you download the firmware file from a trusted website, that you check its size and checksum before uploading it to your router, and that you select the correct file for your device.
How to Troubleshoot Firmware Update Failures
If you encounter any failures or errors during or after updating the firmware of your router, you can try some troubleshooting steps, such as:
Check the power supply and connection of your device. Make sure that your router and computer are plugged into a reliable power source and have enough battery life. Make sure that your router and computer are connected via a stable Ethernet cable or wireless network, and that there is no interference or obstruction in the signal.
Use a reliable cable, wireless signal, or memory card for the update source. If you are updating your router via an Ethernet cable, make sure that it is not damaged or loose. If you are updating your router via a wireless network, make sure that the signal is strong and stable. If you are updating your router via a memory card, make sure that it is formatted and compatible with your device.
Download the firmware file again from a trusted website. If the firmware file you downloaded is corrupted, incomplete, or incompatible with your device model or hardware revision, you may need to download it again from a trusted website, such as [20](http://support.dlink.com) or your local D-Link support website. Make sure that you select the correct file for your device and check its size and checksum before uploading it to your router.
Make sure the firmware file matches your device model and hardware revision. If the firmware file you downloaded does not match your device model or hardware revision, it may cause problems with the update process or result in a failed update. You can check your device model and hardware revision by looking at the label on the bottom of your router or by logging into its web interface and going to Status > Device Information. The model number and hardware revision will be displayed under Model Name and Hardware Version. Make sure that they match the firmware file you downloaded.
