I already Have a WRT54G router - How do I make it WifiTastic?

If you already have a Wrt54G (or WRT54GS, or WRT54GL) router and some technical confidence, you can easily install WifiTastic firmware on your router.

  • It's easy to install and it's free. Just follow these 10 steps to give WifiTastic a try!.
  • If you decide WifiTastic isn't for you, it's easy to return to your previous firmware.

10 Steps to an easy install :

  1. Download the firmware from here
  2. Find out exactly which version of the WRT54g router you are using. The picture below shows the sticker that you will find under your router. Check the model first - often this shows the version number as well (e.g. Wrt54G v4) - though if it doesn't, then check the S/N prefix to determine the version.

  5. Make sure that you are connected to your router via an Ethernet cable, and NOT via a wireless connection. Your network cable should run from one of the output ports on the router (numbered 1-4) to the network port on your computer. Turn off the wireless connection on your PC or laptop so that you can be certain that you are connecting via the Ethernet cable!
  6. Open your router's admin page. Open your web browser (Firefox, Opera, Internet Explorer, etc) and type the address You should now be asked for a password to administer your router. The default password (if you haven't chosen one of your own) is “admin” (no inverted commas, and all lower case).

  9. Click the ‘Upgrade' button.
  10. Your router will now upgrade itself. It could take up to 5 minutes (give it 10 to be safe). DO NOT TURN OFF THE POWER! DO NOT PRESS THE RESET BUTTON until the upgrade is completed.
  11. That's it!

Now you are ready to go!

Open your web browser (Firefox, Opera, Internet Explorer, etc) and type the address again. This will take you to the new firmware - follow the links to get started!
