ZTE ZXV10 W300 Firmware: How to Update and Why You Should

The ZTE ZXV10 W300 is a wireless router that supports ADSL (Asymmetric Digital Subscriber Line) technology. It is widely used by many internet service providers and users around the world. However, like any other device, it may have some issues or vulnerabilities that can affect its performance and security. That is why it is important to update its firmware regularly.


Firmware is the software that runs on the router's hardware. It controls how the router functions and communicates with other devices. Updating the firmware can improve the router's stability, speed, security, and compatibility. It can also fix some bugs or glitches that may cause problems or errors.

However, updating the firmware is not as simple as clicking a button. It requires some preparation and caution. If done incorrectly, it may damage the router or make it unusable. Therefore, before you proceed, you should follow these steps:

  • Backup your router's settings and data. You can do this by logging into the router's web interface and choosing Maintenance > Backup/Restore > Backup Settings. This will download a file that contains your router's configuration. You can use this file to restore your settings later if needed.

  • Download the latest firmware from the official website of your router manufacturer. You can find the firmware for ZTE ZXV10 W300 at [this link]. Make sure you choose the correct version and model of your router.

  • Connect your computer to the router using an Ethernet cable. Do not use a wireless connection, as it may be unstable or interrupted during the update process.

  • Disable any firewall or antivirus software on your computer. They may interfere with the update process or block some files.

  • Make sure your router has enough power and do not turn it off or unplug it during the update process. This may cause irreparable damage to the router.

Once you have completed these steps, you are ready to update your firmware. To do this, follow these steps:

  • Log in to your router's web interface using the IP address in your browser [] and login with the admin username and password admin/admin (page 13 of [the manual]).

  • Click on Interface Setup tab and LAN sub-tab. (page 24 of [the manual]).

  • Locate the DNS section, change the DNS Relay to "Use User Discovered DNS Server Only".

  • Set the Primary and Secondary DNS servers to and respectively. These are the DNS servers of OpenDNS, a service that provides faster and safer internet access.

  • Save your settings and wait for the router to reboot.

  • Click on Maintenance tab and find Update or Firmware Update.

  • Press on Choose file and pick the downloaded firmware file.

  • Click on Upload and wait for the update process to complete. Do not interrupt or close the web interface during this time.

  • When the update is done, you will see a message saying "Update successfully". The router will reboot automatically.

  • Log in to your router's web interface again and check if everything is working properly.

Congratulations! You have successfully updated your ZTE ZXV10 W300 firmware. You can now enjoy a better and more secure internet experience with your router.

If you encounter any problems or errors during or after the update process, you can try these solutions:

  • Restore your router's settings using the backup file that you created before the update. You can do this by logging into the router's web interface and choosing Maintenance > Backup/Restore > Restore Settings.

  • Reset your router to factory defaults by pressing and holding the reset button on the back of the router for about 10 seconds. This will erase all your settings and data, so you will need to reconfigure your router from scratch.

  • Contact your router manufacturer's support team or your ISP if you are using leased equipment. They may be able to help you with troubleshooting or provide you with a replacement router.
