Links of InterestEdit


  1. Read the Peacock Announcement
  2. Download THIS Newd_Mini file.
  3. Ensure you have a physical ethernet connection to your router, and disable your wireless adapter, antivirus/firewall protection, and any software that makes strong use of your network (BitTorrent, Streaming Audio/Video, etc).
  4. Perform a hard 30/30/30 reset.
  5. Navigate to in your web browser of choice.
  6. Enter no username, and the password "admin".
  7. Go to the administration tab. Click on firmware upgrade.
  8. Browse to the .bin file you downloaded in step 2
  9. Click on the upgrade button and WAIT for the upgrade successful message.
  10. Power cycle your router. Wait until you can see the DD-WRT password screen at [1].
  11. Perform another 30/30/30 reset on your router. Wait until you can see the password screen at [2].
  12. Set a new username and password, and continue on to configure your router like normal.

You can now upgrade to any generic DD-WRT build except Mega and Micro. Be sure to always do a hard reset prior to flashing another build, do a power cycle followed by another hard reset after flashing, and NEVER re-use a configuration file from a previous build or another router. Always reconfigure from scratch.


If dd-wrt is already on the router follow these instructions. If stock firmware is on the router follow the flashing instructions.

  1. Check for recommended builds here first.
  2. Set your computer to a static IP of (or to whatever subnet the router is on) Disable all firewalls and security. Disable wireless on your computer and only have the router connected to the flashing computer by the ethernet cable between the two.
  3. Hard reset or 30/30/30 (If the router supports it, if not, reset to defults in the GUI) prior to flashing. Wait. Check for password page on re-login and change password.
  4. Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
  5. least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
  6. Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
  7. Wait for the lights to return to normal usually about 2 minutes.
  8. Hard reset or 30/30/30 again (If the router supports it, if not, reset to defults in the GUI). Wait. Check for the password page and re-login to change the password. Then you can reconfigure your settings manually.
  9. Once configured set your computer back to autoIP and autoDNS.

Important1: This Hard reset or 30/30/30 works fine for Asus router, but you do have to power cycle after the reset.

Important2: After you flash the firmware, and before you do the hard reset, the router will be building some nvram settings. YOU MUST WAIT FOR THIS TO FINISH PRIOR TO DOING ANYTHING WITH THE ROUTER INCLUDING A HARD RESET. Usually, you can tell when this process is completed by the WAN light coming on, but it does take several minutes. Go have a beer. There are starting to be more and more people who BRICK their routers by not waiting until the nvram is rebuilt, PRIOR to doing a hard reset. YOU NEED TO WAIT!

Security LEDEdit
  • The security LED will not light up after flashing on version 1.1. To fix this, go to Administration > Commands, type in the following and then click Save Startup:
while sleep 1; do if [ `nvram get wl0_security_mode` = "disabled" ]; then gpio enable 3; else gpio disable 3; fi; done &

As posted by osmosis

On the wiki for 150N is posted

root@DD-WRT:~# gpio enable 5 #(SECURITY LED - off - green)
root@DD-WRT:~# gpio disable 5 #(SECURITY LED - on - green)
root@DD-WRT:~# gpio disable 3 #(SECURITY LED - on - amber)
root@DD-WRT:~# gpio enable 3 #(SECURITY LED - off - amber)

this applies for the WRT300Nv1.0 as well so to incorporate the amber into the mix as not secure: Also confirmed working on the WRT300N v1.1 WifiShadow 02:40, October 1, 2010 (UTC)
