How to flash a router

[Professor]

Firmware update of a router is an important process that can improve the stability, security and functionality of the device. Below is a general guide to flashing a router. Since different brands (TP-Link, D-Link, ASUS, Xiaomi, etc.) have their own characteristics, I will describe a universal process and also give advice for different cases.

Preparing for firmware​

1. Make sure the update is necessary:
   • Check the current firmware version in the router settings.
   • Visit the manufacturer's official website and compare with the current version.
2. Save current settings (if possible):
   • Most routers have the ability to export the configuration (backup copy of settings).
3. Connect the router to the computer via cable:
   • This will ensure a more reliable connection during flashing.
4. Do not use Wi-Fi when flashing - only wired connection.
5. Make sure the power supply is stable:
   • Do not turn off the router during the update, otherwise it may "break".
6. Download the new firmware from the official website:
   • Select your router model and download the latest firmware version.

Steps to flash a router via a web interface​

1. Open your browser and go to your router control panel:
   • Typically the address is: http://192.168.0.1 or http://192.168.1.1 (may differ).
   • The default login and password are usually: admin / admin or admin / password.
2. Go to the "Firmware Upgrade" section.
   • It can be found in the sections "System Tools", "Maintenance", "Additional", etc.
3. Select the downloaded firmware file (.bin or .trx) and click "Update".
4. Wait for the process to complete:
   • The router will reboot automatically.
   • Do not turn it off or close your browser until the process is complete.
5. After updating, please log in to the interface again and check the firmware version.

Important recommendations​

• Never flash your device with incompatible firmware versions - you may damage your device.
• If the settings disappear after flashing, download the backup copy if it was saved.
• Some models require a full reset of settings after flashing (reset button).
• Some brands (for example, ASUS) have a special utility for updating firmware via USB.

Examples by brand:​

TP-Link:​

• Login address: 192.168.0.1
• Section: System Tools → Firmware Upgrade

D-Link:​

• Address: 192.168.0.1 or dlinkrouter.local
• Section: Administration → Firmware Update

ASUS:​

• Address: 192.168.1.1
• Раздел: Advanced Settings → Administration → Firmware Upgrade

Xiaomi (Mi WiFi):​

• You can do this via the Mi WiFi app or web interface.
• The update often happens as OTA (over the air), but you can use .bin files.

What to do if the router "glitches" after flashing the firmware?​

• Reset the settings using the RESET button.
• Try to reflash again.
• If the device does not turn on or blinks, you may need recovery firmware via TFTP or a special utility.

If you specify the specific model of your router, I can give detailed step-by-step instructions specifically for it.

Flashing the router (installing new firmware) may be required to update functionality, fix vulnerabilities, or install alternative firmware (e.g. OpenWRT, DD-WRT). Here is a step-by-step guide:

1. Preparation​

• Find out the exact model of your router (usually indicated on the sticker at the bottom).
• Download the official firmware from the manufacturer's website or an alternative one (if required).
• Connect the router to the PC via LAN cable (Wi-Fi may be disconnected during firmware upgrade).
• Save the current settings (if necessary) via the web interface (usually in the Administration → Backup section).

2. Login to the web interface​

1. Open your browser and enter your router's IP (usually 192.168.0.1, 192.168.1.1 or 192.168.10.1).
2. Enter login/password (by default it is often admin/admin or indicated on the router sticker).

3. Installing new firmware​

For official firmware:​

1. Go to the Firmware Update section (may be called System Tools → Firmware Upgrade).
2. Click Browse, select the downloaded firmware file (usually .bin or .trx).
3. Start the update process. Do not turn off the router until it is complete!

For alternative firmware (OpenWRT, DD-WRT):​

1. Make sure your model is supported (check openwrt.org or dd-wrt.com).
2. Download the appropriate firmware file.
3. In the router's web interface, select manual download and specify the firmware file.
4. Wait for the reboot (may take 5-10 minutes).

4. After flashing​

• The router may reset to factory settings.
• If something goes wrong (for example, the router "freezes"), try resetting it with the Reset button (hold for 10-30 seconds).
• Alternative firmware may require additional manual configuration.

5. Important Warnings​

• Do not interrupt the process - this may "kill" the router.
• Do not use firmware from other models - this will lead to damage.
• If the router does not turn on after flashing, you may need to restore it via TFTP (depending on the model).
