[edit] Procedure

 **NOTE**:  See model specific prerequisite info above first.

 **NOTE**:  Reset to defaults is recommended if you are upgrading from a very old build (> 6 months).
 **NOTE**:  Do not restore a backup from one version to another version of DD-WRT, as nvram variable names may have changed.

  1. Connect your computer to your router with an Ethernet cable.
  2. Open a web browser and navigate to http://192.168.1.1 (or whatever you set your router IP to).
  3. Enter username and password as required.
  4. Go to Administration -> Firmware Upgrade
    • Leave Do Not Reset selected for After Flashing
  5. Click on Browse and select the appropriate previously downloaded dd-wrt-xxxxxx-webflash.bin file specific to your router model version.

    • The firmware update starts and the router restarts. The firmware update process takes about five minutes.

     **CAUTION**:  After you start the firmware update, do not try to go online, turn off the router, or do anything else to the router until it finishes restarting.

  8. If the webUI does not automatically go back to the Setup -> Basic Setup page, or does not stop at the progress bar page to allow you to click Continue after waiting at least five minutes (i.e. if you get a "Connection Reset" or other error page in your browser), enter http://192.168.1.1 (or whatever your router IP address is) manually or click and hold the "Back" button and select the appropriate history entry.
