ZTE MF190K ATExt Port (COM22) Driver

The ZTE MF190K ATExt Port (COM22) driver helps Windows recognize the AT-command interface exposed by a ZTE MF190K USB modem. It is intended for users setting up the modem, restoring a missing serial port, or troubleshooting software that cannot communicate with the device.

Key Features

• AT-command communication: Enables compatible modem software to access the device’s AT-command interface for supported control and status functions.
• Virtual serial port access: Allows the USB modem interface to appear as a COM port in Windows Device Manager. COM22 is the assigned port name on this system; the number may differ on another computer.
• Windows compatibility: Intended for Windows 10, 8.1, 7, Vista, and XP when the correct driver package is selected for the operating system and architecture.
• Device recognition: Can help resolve an unrecognized ATExt interface or a missing-driver warning when the package matches the connected hardware.

How to Install ZTE MF190K ATExt Port (COM22) Driver

1. Check your system and device. Confirm your Windows version and whether it is 32-bit or 64-bit. In Device Manager, check the modem interface’s hardware IDs if you need to verify the driver match.
2. Select the appropriate package. Before starting a ZTE MF190K ATExt Port (COM22) driver download for Windows, review its compatibility details. Choose a trusted free download, and confirm that the latest version available supports your hardware. For Windows 10/11 systems, note that Windows 11 support is not listed here and should not be assumed.
3. Prepare the files. Extract the downloaded archive if necessary and scan it with your security software. Close any modem-management applications before proceeding.
4. Install the driver. Run the supplied installer and follow its instructions. If no installer is included, open Device Manager, right-click the relevant device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Restart Windows if prompted, reconnect the modem, and check that the ATExt port appears without a warning icon. Ensure your compatible modem software uses the COM number currently assigned by Windows.

Keep the driver updated when a verified, compatible release addresses a connection problem or improves support for your setup. Before you update a working installation, retain the previous package or create a restore point so you can recover if needed.
