ZTE MF667 ATExt Port (COM6) Driver

The ZTE MF667 ATExt Port (COM6) driver helps Windows recognize the AT-command serial interface exposed by the ZTE MF667 USB modem, allowing compatible software to communicate with the device. It is useful when setting up the modem, restoring a missing port, or troubleshooting an unrecognized USB interface in Device Manager.

This download is intended for Windows 10, 8.1, 7, Vista, and XP. If you are comparing Windows 10/11 compatibility, note that Windows 11 is not included in the listed supported systems; verify compatibility before attempting installation.

Key Features

• AT-command communication: Provides access to the modem’s AT-command interface for compatible connection-management and diagnostic applications.
• USB serial-port recognition: Helps Windows identify the ATExt interface as a COM port rather than an unknown device.
• Software integration: Allows applications that require a serial connection to locate and communicate with the appropriate modem interface.
• Support for listed Windows versions: Intended for supported Windows releases, subject to the operating-system and architecture requirements of the selected driver package.

How to Install ZTE MF667 ATExt Port (COM6) Driver

1. Check your Windows configuration. Confirm your Windows version and whether it uses a 32-bit or 64-bit architecture. Select a package that matches both.
2. Choose a compatible package. Before starting your ZTE MF667 ATExt Port (COM6) driver download for Windows, review the package details. For a free download, use a trusted source and avoid installers that bundle unrelated software.
3. Extract and install the driver. If the package includes a setup program, follow its instructions, including any prompts about when to connect the modem. For a driver-only package, extract the files to an accessible folder.
4. Use Device Manager if needed. Connect the modem, locate its unrecognized or ATExt interface, right-click it, and choose the driver update option. Browse to the extracted driver folder and follow the prompts.
5. Verify the result. Restart Windows if requested, then check Device Manager for the ATExt port without a warning icon. Windows may assign a number other than COM6; select the actual assigned port in your modem software.

Keep the driver updated when a compatible release addresses a problem you are experiencing. Check that the latest version supports your specific modem and Windows configuration before you update, and retain a working package in case you need to roll back.
