Wrk54g V2 Firmwarel

How to Update the Firmware of Your Linksys WRT54G V2 Router

The Linksys WRT54G V2 is a wireless router that supports WiFi and five switched Ethernet ports. It has two removable antennas connected through Reverse Polarity TNC connectors. It is one of the models in the Linksys WRT54G series, which are popular among home and small office users for their versatility and customizability.

Updating the firmware of your router can improve its performance, security, and compatibility with new devices and features. However, updating the firmware incorrectly can also cause problems or even brick your router. Therefore, it is important to follow the instructions carefully and backup your settings before proceeding.


What You Need

  • A computer connected to the router via Ethernet cable or WiFi.

  • The latest firmware file for your router model, which you can download from [Linksys Official Support].

  • A web browser that can access the router's web-based setup page.

How to Update the Firmware

  • Open your web browser and enter in the address bar. This is the default IP address of your router. If you have changed it, use the new one instead.

  • You will be prompted to enter a username and password. The default username is blank and the default password is admin. If you have changed them, use the new ones instead.

  • Once you are logged in, click on Administration in the menu bar and then click on Firmware Upgrade.

  • Click on Browse and locate the firmware file that you downloaded earlier. Select it and click on Open.

  • Click on Start Upgrade and wait for the process to complete. Do not turn off or disconnect your router or computer during this time.

  • When the upgrade is done, you will see a message saying "Upgrade Successful". Click on Continue and then reboot your router by unplugging it from the power source and plugging it back in.

  • After rebooting, you may need to reconfigure some of your settings, such as wireless security, port forwarding, etc. You can access the web-based setup page again using the same steps as before.


If you encounter any problems during or after updating the firmware, here are some possible solutions:

  • If you cannot access the web-based setup page, try resetting your router by pressing and holding the reset button on the back panel for 10 seconds. This will restore your router to its factory default settings. You will need to reconfigure your settings afterwards.

  • If you get an error message saying "Upgrade Failed" or "Upgrade are failed", try downloading the firmware file again and make sure it is not corrupted. You can also try using a different web browser or computer to perform the upgrade.

  • If your router does not boot up or respond after upgrading, you may have bricked it. This means that the firmware was not compatible with your hardware version or was installed incorrectly. You can try to unbrick your router using a method called TFTP recovery, which involves using a special software tool and an Ethernet cable to upload a working firmware to your router. You can find more information about this method [here].


Updating the firmware of your Linksys WRT54G V2 router can enhance its functionality and security, but it also involves some risks. Therefore, you should always backup your settings before upgrading and follow the instructions carefully. If you encounter any problems, you can try some of the troubleshooting tips above or contact Linksys support for assistance.
