Installation DD-WRT

DD-WRT is a third party developed firmware released under the terms of the GPL for many ieee802.11a/b/g/h/n wireless routers based on a Broadcom or Atheros chip reference design.

Step 1. Is your router supported?
You can check your router that is supported DD-WRT

Step 2. Downloading DD-WRT
Download the latest stable release from
Link: http://www.dd-wrt.com/dd-wrtv3/dd-wrt/downloads.html
Recommend dd-wrt.v23_sp2_standard.zip

Step 3. Upload the Firmware
1. You should be in the Web GUI of the router. Go there now.
2. Click the "Administration" tab
3. Click the "Firmware Upgrade" sub-tab.
4. (Only applicable when DD-WRT is already installed.) Click the "No reset" radio button (works for me, but please double check if "Firmware Defaults" would be better!).
5. Click the "Browse" button and select the DD-WRT .bin file you downloaded and confirmed.
6. Click the "Upgrade" button.
7. The router will take a few minutes to upload the file and flash the firmware. During this time, the power light will flash.
8. A new page will open confirming that the upload was successful (if not). Now wait about 5 minutes before clicking "Continue".
9. If flashed successfully you will now be at the DD-WRT web interface.

Step 4. Testing Login In to the Web GUI
For DD-WRT firmware, Username: root and Password is admin.
