Tenda D810r | Firmware Update

Now we get to the main event. Follow these instructions precisely.

Select the File: Click "Browse" or "Choose File" and select the .bin firmware file you extracted earlier.

Initiate the update: Click "Upgrade" or "Update."

Wait patiently: A progress bar will appear. Do not close the browser, turn off the PC, or unplug the router. The router LEDs will blink erratically—this is normal. The process takes approximately 2 to 3 minutes.

Automatic Reboot: The router will reboot automatically. Once the power LED stabilizes (solid green), the update is complete.

Hard Reset (Highly Recommended): Even after an upgrade, old configuration variables can linger. Press and hold the Reset button (pin-hole on the back) for 10 seconds to restore factory defaults.

Reconfigure: Log back into 192.168.1.1 and re-enter your ISP settings (VPI/VCI, username, password) and Wi-Fi name/password.

Do not skip this step! Updating firmware carries a small risk. If the power goes out during the update, you could "brick" your router (make it unusable). tenda d810r firmware update
