Update Router System Software
Keep your network safe by updating firmware, optimizing security parameters, and executing backup configurations.
A router's firmware is its internal embedded operating system. Unlike software on your PC that updates automatically in the background, many routers require manual verification. Applying firmware updates patches critical CVE security vulnerabilities, fixes Wi-Fi driver crashes, and adds support for newer networking standards.
1 Two Ways to Upgrade Firmware
Direct Dashboard Update
Navigate to Administration ➔ Firmware Upgrade. Click "Check for Updates". If a new version exists, click "Install" to download and flash automatically.
Offline .BIN Image File
Download the exact firmware file (e.g. firmware_v1.4.bin) from the hardware support page. Use the "Browse" button inside the web GUI to upload and flash.
3 Critical Safety Rules During Firmware Flashing
- NEVER power off or unplug the router: Interrupting power while rewriting the flash memory partition can permanently brick the device.
- Use a wired Ethernet cable: Do not perform manual firmware upgrades over Wi-Fi, as wireless drops during upload can corrupt the image payload.
- Match exact hardware revision: Many router models have multiple hardware versions (e.g. V1, V2, V3). Verify the hardware version on your bottom sticker before downloading files.
Pro-Tip: Export a Configuration Backup First
Before applying any major firmware upgrade, navigate to System Settings ➔ Backup & Restore and click "Backup Configuration". This saves your custom Wi-Fi passwords, DHCP reservations, and port forward rules to a local file on your PC.
