How to Upgrade Your OpenWRT?
Unlock the full potential of your router by upgrading its firmware with OpenWRT! This guide provides a comprehensive walkthrough of the flashing process, offering prerequisites, precautions, and clear instructions to help you enhance your router’s performance and access advanced features.
What is OpenWRT?
OpenWRT is an open-source firmware for routers and other embedded devices. It provides advanced customization, superior performance, and features far beyond what stock firmware offers. If you’re ready to upgrade or switch to a new firmware image, this guide will show you how to do it step by step.
Why Flash a New Firmware Image?
Flashing a new firmware image involves replacing your router’s existing firmware with a newer version or a completely different firmware. This process can improve performance, fix bugs, and unlock features not available in the original firmware.
Prerequisites
- Compatible Router: Verify that your router is supported by OpenWRT. Check the OpenWRT Supported Devices page for compatibility.
- New Image Firmware: Download the appropriate firmware version for your router model from the OpenWRT Downloads page.
- Computer: You’ll need a computer to access your router’s web interface and upload the firmware.
- Ethernet Cable: Connect your computer to the router via Ethernet for a stable connection.
Step-by-Step Guide to Flash OpenWRT Firmware
1. Access the Router’s Web Interface
- Connect your computer to the router using an Ethernet cable.
- Open a web browser and enter the router’s default IP address (
192.168.1.1) into the address bar. - Log in with your credentials. If unchanged, the default username is
root, and the password field is left blank.
2. Backup Your Settings
Before proceeding, it’s recommended to back up your current router settings. This ensures you can restore your configuration if needed. Most routers have a "Backup" option under the "System" tab.
3. Navigate to the Firmware Upgrade Section
In the web interface, go to the "System" tab. Look for options like "Firmware Upgrade" or "Flash Firmware."
4. Upload the New Firmware
- Click the "Browse" or "Choose File" button and select the firmware file downloaded earlier.
- Click the "Upload" or "Flash" button to start the process.
5. Wait for the Flashing Process
The flashing process will take a few minutes. During this time, avoid interrupting the router or your computer.
6. Reboot the Router
After flashing, the router will automatically reboot. Once it restarts, log in again using the default OpenWRT credentials:
- IP Address:
192.168.1.1 - Username:
root - Password: (leave blank)
7. Perform a Factory Reset (Optional but Recommended)
To ensure a smooth transition, it’s best to perform a factory reset. This can be done via the web interface in the "System" section.
8. Restore Your Settings
After the router has rebooted, restore your backed-up settings if necessary. Configure additional features as needed to optimize your network.
