Install Guide |
---|
The stock firmware from Linksys on the WRT54G v4 won't accept a firmware image over 3MB in size (you will get the error: :"Upgrade are failed!" if you try) so you will need to flash the mini version of DD-WRT onto the router BEFORE flashing any other versions.

Upgrading[edit]
Upgrade DD-WRT |
---|
Updating DD-WRTIf dd-wrt is already on the router follow these instructions. If stock firmware is on the router follow the flashing instructions.
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! |

- 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.
