Installation Instructions

Step-by-step instructions from out-of-the-box factory firmware

To install dd-wrt on a D-Link DIR-825 you can flash it directly from the router's web admin page (yes, that is correct... from D-Link's standard web interface). These are the steps to follow:

  1. Download the correct factory to ddwrt firmware for you router
  1. Set your IPv4 network adapter to the following in your windows network configuration to: IP Address: 192.168.0.2, Subnet Mask: 255.255.255.0, Gateway: 192.168.0.1
  2. Physically connect the router ethernet port #1 to your computer ethernet port (NO WIRELESS!)
  3. Perform the 30/30/30 procedure:
    1. With power on, hold the reset button down for 30 seconds.
    2. Without releasing the reset button, unplug the router. Continue holding the reset button for 30 more seconds.
    3. Without releasing the reset button, plug the power back in and continue to hold the reset button for 30 more seconds.
    4. Release the reset button. The power light should be flashing on and off yellow.
  4. In Internet Explorer or Firefox enter http://192.168.0.1
  5. You should see a screen titled "Firmware Upgrade System".
  6. Select the “factory-to-ddwrt_XX.bin" file you downloaded and click the Send button to flash your router. As the firmware is uploaded and installed you will see the screen start counting to 100 percent. The power light will remain out during this process. At 100% the power light the power light will flash yellow and the router will reboot. The router globe will be yellow, the power will be blue, the 2.4/5GHz will be flashing blue.
  7. Remove the static IP from your computer network settings.
  8. Using Internet Explorer or Firefox go to: http://192.168.1.1 and You should see the DD-WRT screen to change your password.
  9. You should now be at the System Information screen.

RETURNING TO STOCK FIRMWARE

1. Download the stock firmware at ftp://ftp.dlink.com/Gateway/dir825_revB/Firmware/dir825_revB_FW_205NA.zip

2. Set your IPv4 network adapter to the following in your windows network configuration to: IP Address: 192.168.0.2, Subnet Mask: 255.255.255.0, Gateway: 192.168.0.1

3. Physically connect the router ethernet port #1 to your computer ethernet port (NO WIRELESS!)

4. Perform the 30/30/30 procedure, using the same method you used to flash DD-WRT firmware.

5. You should see the stock "Firmware Upgrade System" screen.

6. Select the stock firmware that you downloaded in step 1 and click the Send button.

7. Remove the static IP from your computer settings 1 minute after clicking send.

8. Using Internet Explorer or Firefox go to: http://192.168.1.1 and You should see the DD-WRT screen to change your password.
