ZTE MF667 ATExt2 Port (COM14) Driver

The ZTE MF667 ATExt2 Port (COM14) driver helps Windows recognize an auxiliary serial interface exposed by the ZTE MF667 USB modem, allowing compatible software to communicate with the device. You may need it when setting up the modem, reinstalling Windows, or troubleshooting an unrecognized port in Device Manager.

Key Features

• USB-to-serial communication: Enables compatible modem software to access the MF667’s auxiliary AT-command interface over USB.
• Device recognition: Helps Windows identify the ATExt2 port correctly rather than displaying it as an unknown device when the appropriate driver is missing.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows edition and 32-bit or 64-bit architecture.
• Port configuration: Makes the interface available through Device Manager for checking driver information and COM-port settings. COM14 is an assigned port number and may differ on another computer.

How to Install ZTE MF667 ATExt2 Port (COM14) Driver

1. Check your system and device. Confirm your Windows version and architecture, then connect the ZTE MF667 to a working USB port. In Device Manager, look under Ports (COM & LPT) or Other devices.
2. Choose a compatible package. Before starting a ZTE MF667 ATExt2 Port (COM14) driver download for Windows, verify that the package supports your modem and operating system. Prefer a trusted source; a free download should not require unrelated software.
3. Extract and install. Unzip the downloaded archive if necessary. Run the included installer, or right-click the device in Device Manager, select Update driver, and browse to the extracted driver folder.
4. Reconnect or restart if prompted. Allow installation to finish before unplugging the modem. Reconnect it or restart Windows if the installer requests it.
5. Verify recognition. Check that the port appears without a warning icon. If troubleshooting on Windows 10/11, note that Windows 11 is not among the listed supported systems; do not assume compatibility without confirmation from the driver provider.

Keep the driver updated when a compatible release addresses a problem you are experiencing. Check the latest version against your hardware and Windows edition before you update, and retain a working installer in case you need to roll back. This port driver supports one modem interface; other MF667 functions may require additional drivers or connection software.
