Huawei B311-221 Firmware Updated: Guide to the Latest Version

Updating the firmware on your Huawei B311-221 4G router is essential for improving connection stability, fixing security vulnerabilities, and sometimes unlocking new features like enhanced SMS management or better VPN support

Huawei Hilink App (Android/iOS) – Some updates are distributed via the app. Go to Device > Check for Updates.

Q2: My router says “No update available” but I know a newer version exists. Why?

Carriers and Huawei stage rollouts by IMEI range or region. You can force the update using the manual method explained above.

Auto-Update: You can enable Auto-update in the "Manage Updates" section. This allows the router to automatically download and install updates during "idle time" (typically between 3:00 AM and 5:00 AM).
