NOTE: These instructions only apply to the Linksys WRT54Gv8 and WRT54Gv8.2. They do not work for the WRT54Gv8.1. If you want to flash a WRT54Gv8.1, pls read this.

How To Flash the WRT54G v8 Using v24 (including sp1)

  1. Configure your computer's local lan ethernet address to 192.168.1.100, subnet 255.255.255.0, gateway 192.168.1.1 . Then connect an Ethernet cable to your computer and port 1 of your WRT54Gv8 router. (Do Not Use Wireless)
  2. Unplug the power cord from the WRT54Gv8.
  3. Push the reset button while plugging in the power cord and hold the button for about 20 seconds.
  4. Open your browser to http://192.168.1.1. (Note: Some people, such as sth had problems with Firefox (in June 2008), while others, such as dennisn had no such problems with Firefox 3.0.3 in Dec 2008), with the next step (and later on when trying to save changes in dd-wrt's web gui). Sth had to Recover from a Bad Flash.)
  5. Use the firmware upgrade dialog to flash vxworkskillerGv8-v3.bin.
  6. WAIT for at least two minutes before you continue! (longer is better) Give vxworks killer plenty of time to do its magic! After the 2 minutes is up, if you notice a dialog asking you to reboot the router, go ahead and power cycle the router by unplugging the power cord and plugging it back in again.
  7. You will not be able to browse the WRT54 at this point, but you should be able to ping 192.168.1.1. If the router doesn't reply you haven't set your computer's network settings correctly (on step 1)
  8. Now it's time to flash the DD-WRT firmware using TFTP
  9. The file will now be transfered and flashed to your router. After this is done, dd-wrt will automatically boot. After about a minute, you can browse dd-wrt on your router at http://192.168.1.1.

If you had previously flashed your router with a beta/RC version of v24 and are currently experiencing issues with LAN port 4 and/or wireless, an upgrade to the CFE-Updater and v24 stable should fix it.

How To Return To Your Original Linksys Firmware V8

  1. Open the Administration tab in dd-wrt and choose the Firmware Upgrade Tab
  2. Choose reset to default settings from the drop down.
  3. Browse and select vxworksrevert-Gv8-v3.bin. It will install the revert firmware and give you a rebooting indicator on the screen. When it is done it will give you a Confirm button on the screen. Click on Confirm. Your power light will be flashing on your router.
  4. Power cycle the router by unplugging the power cord and plugging it in again.
  5. Open your browser and enter into the address bar http://192.168.1.1
  6. Use the firmware upgrade dialog to flash your original linksys firmware WRT54Gv8_v8.00.0_fw.bin. When the upgrade success screen comes up wait 2 minutes.
  7. Power cycle the router by unplugging the power cord and plugging it in again.
  8. Open your browser and enter into the address bar http://192.168.1.1

You are now back to your factory firmware.
