ZTE MF192 AT Port (COM4) Driver

The ZTE MF192 AT Port (COM4) driver allows Windows to recognize the AT-command interface of a ZTE MF192 USB modem and communicate with it through a serial port. You may need it if Device Manager shows an unrecognized device, the AT port is missing, or compatible modem software cannot access the device.

Key Features

• AT-command communication: Enables compatible software to send supported modem commands, such as requests for device information or connection status.
• Serial-port recognition: Helps Windows identify the modem’s AT interface as a COM port. Although this device is listed as COM4, Windows may assign a different number on your computer.
• USB interface support: Provides access to the AT port exposed by the modem’s USB connection. Other modem functions may require additional components from the ZTE driver package.
• Windows compatibility: Intended for Windows 10, 8.1, 7, Vista, and XP when using a package that matches your system version and architecture.

How to Install ZTE MF192 AT Port (COM4) Driver

1. Check your Windows system. Confirm your Windows version and whether it is 32-bit or 64-bit. For Windows 10/11 systems, note that Windows 10 is listed as supported here; Windows 11 compatibility is not confirmed.
2. Choose a matching package. Before starting a ZTE MF192 AT Port (COM4) driver download for Windows, verify that the package supports your modem and operating system. If offered as a free download, still check its source and digital signature.
3. Prepare the files. Extract the downloaded archive if necessary. If the package includes an installer, run it and follow its instructions, including any guidance on when to connect the modem.
4. Install manually if needed. Open Device Manager, locate the unrecognized device or existing AT-port entry, and select Update driver. Choose the option to browse your computer, then point Windows to the extracted driver folder.
5. Verify recognition. Restart if prompted, reconnect the modem, and check Device Manager for the AT port without a warning icon. Set your compatible application to use the assigned COM number rather than assuming it is COM4.

Keep the driver updated when a compatible release addresses a problem you are experiencing. Check for the latest version from a trusted ZTE source, but confirm compatibility before you update—a newer package is not necessarily suitable for every older modem or Windows edition.
