ZTE MF190K AT Port (COM23) Driver

The ZTE MF190K AT Port (COM23) driver helps Windows recognize the AT-command interface of a ZTE MF190K USB modem, allowing compatible software to communicate with the device. You may need it if the modem’s AT port appears as an unknown device, shows a warning in Device Manager, or is unavailable to your connection or diagnostic software.

Key Features

• AT-command communication: Provides the serial interface that compatible applications use to send modem commands and read responses.
• USB device recognition: Helps Windows identify the modem’s AT port rather than leaving it listed as an unrecognized USB component.
• COM-port access: Makes the interface available to software through an assigned COM port. Although this device is listed as COM23, Windows may assign a different number on another computer.
• Legacy Windows support: Intended for Windows 10, 8.1, 7, Vista, and XP, subject to the compatibility of the specific driver package. This AT-port driver alone may not provide every component needed for mobile broadband connectivity.

How to Install ZTE MF190K AT Port (COM23) Driver

1. Check your Windows configuration. Confirm your operating system and whether it is 32-bit or 64-bit. For Windows 10/11 systems, check compatibility carefully: Windows 10 is listed as supported, but Windows 11 support is not confirmed here.
2. Choose a matching package. Before starting your ZTE MF190K AT Port (COM23) driver download for Windows, verify that the package identifies your device and Windows version. Look for the latest version compatible with your system, and use a trusted free download source.
3. Extract and install the driver. Unzip the download if necessary. Run the included installer, if available, and follow its prompts for connecting or disconnecting the modem.
4. Use Device Manager if needed. If no installer is provided, connect the modem, locate its AT port or unidentified device, and choose Update driver. Browse to the extracted driver folder and follow the instructions.
5. Confirm recognition. Restart Windows if prompted, then check Device Manager for the AT port without a warning icon. Select its actual COM number in your modem software.

Keep the driver updated when a compatible update addresses connection problems or device-recognition issues. Before replacing a working driver, review compatibility information and retain the previous package so you can roll back if necessary.
