The following are the steps that I went through to get DD-WRT v23 installed on a WRT54G v4. I tried to take screenshots of each step as I went, so as not to confuse anyone. Following the instructions found at Steps_to_flash_through_Web_Interface, I was eventually successful in getting DD-WRT installed. I will use some of the text from those instructions as well as inserting my screenshots and other encounters not mentioned in the above link.


1) Download the DD-WRT v23 firmware

2a) Reset through the Web Interface
if you forgot the password or IP of your router, proceed to step 2b.

  • From a PC connected to one of the 4 LAN ports on the router open a web browser and go to the IP of the router (default IP is 192.168.1.1).
  • You will be prompted for username and password. Username is not required. Enter password (default password is admin) and you should be at the Web Interface of your WRT54G v4

  • Click the "Administration" tab.

  • Click the "Factory Defaults" sub-tab.
  • Select "Yes".

  • Click the "Save Settings" button.
  • A warning will pop up, click "ok".

2b) Reset to factory defaults

  • Press and hold the reset button on the back of the router for 30 seconds. This will clear your NVRAM, the configuration and reset the password to admin.

Be aware that if your router currently has an OpenWRT firmware running on it, then using the reset button may brick your router. Research your current firmware to be safe.



3) Upgrade Firmware

Do not turn off the computer, close the web browser, or turn off the router during this process!!!!!
  • From a PC connected to one of the 4 LAN ports on the router open a web browser and go to the IP 192.168.1.1.
 http://angrycamel.com/howtos/dd-wrt/images/DD-WRT_WRT54G_v4_-StockLogin.png



  • You will be prompted for username and password. Leave username blank, enter password admin. Now you should be at the Web Interface of your WRT54G v4.
 http://angrycamel.com/howtos/dd-wrt/images/DD-WRT_WRT54G_v4_-StockLogin.png



  • Click the "Administration" tab
 http://angrycamel.com/howtos/dd-wrt/images/DD-WRT_WRT54G_v4_-StockAdministrationTab.png



  • Click the "Firmware Upgrade" sub-tab.
 http://angrycamel.com/howtos/dd-wrt/images/DD-WRT_WRT54G_v4_-StockFirmwareUpgradeTab.png



  • Click the "Browse" button and select "dd-wrt.v23_mini_generic.bin" file you extracted in step 1.
http://angrycamel.com/howtos/dd-wrt/images/DD-WRT_WRT54G_v4_-StockSelectMiniFirmware.png



  • Click the "Upgrade" button.
  • The router will take a few minutes to upload the file, flash the firmware, and then reset.

  • Here is where my experience was a bit different than the instructions said it would be. I never got success message, instead of got a failed message. This is when I started to get a bit nervous that I had bricked my brand new router! So I started reading furiously through all the documentation I could get my hands on about recovering a bricked WRT when I relaunched "192.168.1.1" and found that DD-WRT was working! Don't ask me... but the flashed seemed to have worked perfectly despite the error message I got.

  • Additional note #1: as of version v23 SP1 the default login username/password has changed from <blank>/admin to root/admin.
  • Additional note #2: if you are flashing the router using Firefox, it may warn you a dozen times that some scripts are very slow, giving you the option to stop that script, or continue. You should press continue (or use alternate browser). To fix the unresponsive script issue in Firefox, navigate to about:config, then increase the integer value of dom.max_script_run_time from 5 to 20.

  • If flashed successfully you will now be at the DD-WRT web interface and the Router Name will be DD-WRT.

4) Reset to factory defaults AGAIN

  • Repeat step 2 above. Note: step 2b (the manual way of clearing the NVRAM) is recommended to make sure the radio gets the correct parameters.



5) Upgrade the Firmware to DD-WRT STD v23

  • It is strongly advised that you enable the "Boot Wait" option under the "Administration" tab before continueing. This will help you recover in the future should you flash your router improperly. If you use v23 or higher the "Boot Wait" option is enabled by default.
  • Download the STD Version 23 HERE (dd-wrt.v23.std.zip) or go to the DD-WRT downloads section at http://www.dd-wrt.com/dd-wrtv2/index.php?link=downloads
  • Extract it



  • Click the "Administration" tab
  • Click the "Firmware Upgrade" sub-tab.
 http://angrycamel.com/howtos/dd-wrt/images/DD-WRT_WRT54G_v4_-DD-WRT_UpgradeFirmware.png



  • Hit the browse button and select dd-wrt.v23_generic.bin that you just extracted.

  • You should see the progress of the flash like so:

  • If the upgrade went well then you should see a success message. You're done!

6) ?? Uh-oh ??

  • If your router fails to reboot (power light doesn't stop flashing, no web interface, etc) you will need to Recover from a Bad Flash.
