ZTE MF667 AT Port (COM17) Driver

The ZTE MF667 AT Port (COM17) driver lets Windows recognize the AT-command interface of the ZTE MF667 USB modem, allowing compatible software to communicate with the device. It is useful if you are setting up the modem, reinstalling Windows, or troubleshooting an unrecognized port in Device Manager. This component supports modem control and diagnostics; other modem functions may require additional drivers from the same ZTE package.

Key Features

• Enables communication through the modem’s virtual serial AT port for compatible connection-management and diagnostic tools.
• Helps Windows identify the USB interface correctly instead of listing it as an unknown device or a port with a driver warning.
• Provides the driver component needed for applications that send AT commands to check modem status or manage supported settings.
• Supports installation on Windows 10, 8.1, 7, Vista, and XP when you select a package appropriate for your operating system and architecture.

How to Install ZTE MF667 AT Port (COM17) Driver

1. Check your Windows version and whether it is 32-bit or 64-bit. Before choosing a ZTE MF667 AT Port (COM17) driver download for Windows, confirm that the package lists your system as supported. For Windows 10/11 searches, note that Windows 11 compatibility is not confirmed by the supported OS list above.
2. Obtain the appropriate package from a trusted source. If a free download is offered, verify its origin and check any available release notes to identify the latest version compatible with your system.
3. Extract the downloaded archive, if necessary. Run the included installer and follow its prompts, connecting the modem when instructed. If there is no installer, connect the modem and open Device Manager.
4. In Device Manager, locate the modem’s AT port or the corresponding unrecognized device. Choose Update driver, select the option to browse your computer, and point Windows to the extracted driver folder.
5. Restart if prompted, then check Device Manager for a correctly recognized port without a warning icon. Windows may assign a COM number other than COM17; select the actual assigned port in your modem software.

Keep the driver updated when a compatible release addresses a problem or improves support for your setup. Before you install an update, confirm its compatibility and retain the working package so you can restore it if needed.
