firmware can be updated via the web management page. The process involves downloading the correct version for your hardware from the official site and uploading it manually. 📥 Preparation Identify Hardware Version

The Tenda AC8 firmware has recently been the subject of significant security scrutiny due to several critical vulnerabilities discovered in early 2026. While firmware updates aim to improve performance and fix bugs, current users of specific versions—particularly v16.03.34.06 and v16.03.33.05—are at high risk of remote exploitation.

  • Beamforming+: Enhances signal strength to supported devices.
  • MU-MIMO: Allows the router to communicate with multiple devices simultaneously (dependent on hardware version).
  • Smart Connect: Merges the 2.4GHz and 5GHz bands into a single SSID, automatically steering devices to the best band.
  • Parental Controls: Basic URL filtering and time management (often requires the Tenda Wi-Fi app for full functionality on newer revisions).
