ZTE MF667 ATExt2 Port (COM5) Driver

The ZTE MF667 ATExt2 Port (COM5) driver helps Windows recognize the modem’s USB serial interface so compatible software can communicate with the device using AT commands. It is intended for users whose ZTE MF667 shows an unrecognized port, a missing driver warning, or a communication problem in Device Manager.

Key Features

• USB serial port recognition: Enables Windows to identify the ATExt2 interface exposed by the ZTE MF667 modem.
• AT-command communication: Allows compatible modem utilities to access the port for supported control and diagnostic tasks.
• Device Manager integration: Helps the interface appear under Ports (COM & LPT), where you can check its status and assigned COM number.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP when using a package matched to your operating system and architecture.

How to Install ZTE MF667 ATExt2 Port (COM5) Driver

1. Check your Windows version and system type. Confirm whether your installation is 32-bit or 64-bit before choosing a package. For Windows 10/11 systems, note that Windows 10 is listed as supported, while Windows 11 compatibility is not confirmed here.
2. Choose a compatible package. Before starting your ZTE MF667 ATExt2 Port (COM5) driver download for Windows, verify the supported operating systems and device identifiers. Look for the latest version compatible with your setup rather than assuming every newer release will work.
3. Prepare the downloaded files. Extract the archive if necessary. Whether you choose a free download or an existing modem software package, use a trusted source and scan the files before opening them.
4. Install the driver. Run the included installer and follow its prompts. If no installer is provided, open Device Manager, right-click the affected interface, select Update driver, and browse to the extracted driver folder.
5. Reconnect and verify. Restart Windows if prompted, reconnect the modem, and check that the interface appears without a warning icon. Windows may assign a COM number other than COM5; select the actual assigned port in your modem utility.

Keep the driver updated when a compatible release addresses a problem you experience or improves support for your Windows installation. Before an update, retain the working package so you can restore it if needed. This port driver supports modem communication but does not, by itself, configure mobile broadband service.
