Like any networking hardware, its firmware (the internal operating software) requires periodic updates. These updates patch security vulnerabilities, improve Wi-Fi stability, add new features, and fix bugs.

What’s problematic (negative points)

No official public firmware download – ZTE does not host firmware for this model on its consumer portal. You cannot simply download a .bin file from ZTE’s website.
Risk of bricking – Unofficial or cross-provider firmware can permanently disable the router.
No built-in manual update option – The web interface (192.168.1.1) typically lacks a visible “Firmware Upgrade” section for end users. If it exists, it may be hidden or require a special admin account.
Hard to find correct version – Different ISPs use different hardware revisions, bootloaders, and VLAN settings. Using the wrong firmware will break internet connectivity.

5. After the update

Wait a few minutes for the router to fully restart.
Log back into the admin page.
Check the firmware version in System Information to confirm the update succeeded.
If settings were reset, restore the configuration from the backup you saved (if compatible). Some firmware updates intentionally reset to factory defaults—if so, reconfigure manually using your notes.

Check LAN Ports: Plug a computer into each Ethernet port to confirm connectivity.
Review New Settings: Explore the admin panel for any new sections (e.g., “Mesh Networking” or “Smart Connect”).
