ISPs can push firmware updates that change the menu layout. If your GUI looks different from the steps above, look for similar wording: “WLAN” may be “Wireless”, “Port Forwarding” may be “Virtual Server”. When in doubt, search your exact firmware version (shown at the top of the GUI). This guide is an unofficial community resource. ZTE and its partners are not responsible for configuration changes made by users. Always back up your configuration before making major changes (Management > Backup & Restore > Backup).
