Cybercriminals constantly discover vulnerabilities in router software. An unpatched router can be recruited into a botnet (e.g., Mirai malware), have its DNS hijacked, or leak your traffic. Tenda’s security updates close these backdoors.

Flip your router over. Look for a sticker that says "Model No." (e.g., AC1200, AC10U, AC18, Nova MW6, F3). Do not guess. Installing the wrong firmware will destroy the router.
