FlashingEdit

  1. Read the peacock announcement found here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486
  2. Do a HARD reset on the router according to note 1 of the peacock announcement (30/30/30)
  3. Set a static IP on your computer to 192.168.1.7. Subnet mask should be 255.255.255.0.
  4. Connect the lan cable from your computer to a LAN port of your router. Make sure your router is plugged in. Nothing should be connected to your computer or the router except the lan cable between them. Turn your firewall and any wireless computer connections OFF.
  5. Power cycle the router (uplug the power from the router for 30 seconds and then plug it back in)
  6. Open your browser to 192.168.1.1 by putting that in the browser address window of your browser. You should open the linksys webgui and NOT a page that says Management Mode. If you see management mode, power cycle the router again.
  7. Leave the username blank and enter "admin" as the password
  8. Go to administration and firmware upgrade
  9. Navigate to the folder that you are using, and select dd-wrt.v24_mini_wrt54gs.bin
  10. Hit upgrade
  11. When you get a message that the upgrade is successful, wait FIVE FULL minutes before continuing.
  12. If you don't get success, repeat from steps 6 up to this one. If you still don't get success, clear your browser cache. Try using a different browser as well, to navigate to 192.168.1.1.
  13. When you can access the dd-wrt webgui using a browser at 192.168.1.1, power cycle the router.
  14. When you can again access the dd-wrt webgui using a browser at 192.168.1.1, do another HARD reset on the router.
  15. At this point you can choose to put a different build on, depending on what you needs are.
  16. Reset your computer ethernet connection to auto IP and auto DNS
  17. Check for recommended builds here

UpgradingEdit

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 192.168.1.7. (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. Wait...at 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!

Other NotesEdit

[Comment added 05/03/06 by PhoneBoy] On my WRT54GSv3, I found that the device wouldn't take ANY firmware unless I reset it using the button rather than just factory reset from the web interface. Word of warning. I was able to download and install the firmware for the purposes of getting vpn up and running. The firmware installed and everything is as before. however, still no vpn.
