FLASHING TO DD-WRT

  1. Download "factory-to-ddwrt_NA.bin."
  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:
    • With power on, hold the reset button down for 30 seconds .
    • Without releasing the reset button, unplug the router. Continue
      holding the reset button for 30 more seconds.
    • Without releasing the reset button, plug the power back in and
      continue to hold the reset button for 30 more seconds.
    • Release the reset button. The power light should be flashing on and off yellow.
  5. In Internet Explorer enter http://192.168.0.1
  6. You should see a screen titled "Firmware Upgrade System". Mine is version 1.0.0.2 dated 2008/12/25, yours may vary.
  7. Select the “factory-to-ddwrt_NA.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.
  8. Reconfigure your network adapter to one of the following:
    • STATIC IP Address: 192.168.1.2, Subnet Mask: 255.255.255.0, Gateway: 192.168.1.1
    • DHCP
  9. Using Internet Explorer go to: http://192.168.1.1 and You should see the DD-WRT screen to change your password.
  10. 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.
    • You should see the stock "Firmware Upgrade System" screen.
  5. Select the stock firmware that you downloaded in step 1 and click the Send button.
  6. Reconfigure your network adapter to one of the following:
    • STATIC IP Address: 192.168.1.2, Subnet Mask: 255.255.255.0, Gateway: 192.168.1.1
    • DHCP
  7. Using Internet Explorer go to: http://192.168.1.1 and You should see the DD-WRT screen to change your password.


COMMON PROBLEMS

  • Dramatic reduction of WAN download speed over time.
    • Reboot temporarily clears the problem.
    • Setting TX/RX antenna chains to 1 per BrainSlayer's advice gives stable 65Mb/s connection in NG-mixed mode. (current uptime 1 week without any performance deterioration)
      • Setting TX/RX antenna chains to 1+2 will give a 130Mb/s connection, which this far seems to be equally stable (current uptime 1 week without any performance deterioration)
  • Web GUI slows slowsmdown and becomes unresponsive over time.
    • Reboot temporarily clears the problem.
