Flashing

NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power.

Flashing dd-wrt

WARNING: Requires Micro for DD-WRT, Do not flash anything else!

WARNING: Requires K2.4 for DD-WRT, Do not flash anything else!

Supported by dd-wrt as of = Nov 05, 2009

***Warning*** - There is no Revert for this router at this time

Configure your computer's local lan ethernet address to 192.168.1.7, subnet 255.255.255.0, gateway 192.168.1.1 . Then connect an Ethernet cable to your computer and port 1 of your router. (Do Not Use Wireless)(Nothing else connected to router)
Perform a Hard reset or 30/30/30.
Open your browser to http://192.168.1.1.
Use the firmware upgrade dialog to flash Vxworkskiller-G2V13.bin.
WAIT for at least five minutes before you continue! (longer is better) Give vxworks killer plenty of time to do its magic!
You will not be able to browse the WRT54G2V13 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)
Tftp the DD-WRT firmware to the router, use latest dd-wrt.v24_micro_generic.bin from the folder where you got these instructions; after sucessful tftp, wait 5 min for the router to finish writing new nvram deafults, etc... It should reboot on its own at least 2 times, so give it 5 min and then go to http://192.168.1.1 (If it not reboot on its own, wait another 2 min, and then power cycle it) , you should see the password reset page. Don't worry about changing it at this point.
Perform a Hard reset or 30/30/30.
WAIT for at least 5 minutes before you continue! (longer is better) Give the router plenty of time to to boot.
Browse 192.168.1.1, you should see the password reset page, change it! Then configure.
Check for recommended builds here.

Upgrading

Updating DD-WRT

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

Check for recommended builds here first.
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.
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.
Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
Wait...at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
Wait for the lights to return to normal usually about 2 minutes.
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.
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!
