Mobile Adapter - ETS Application Interface (COM18) Driver

The Mobile Adapter – ETS Application Interface (COM18) driver helps Windows recognize and communicate with the ETS application interface exposed by a compatible Huawei mobile adapter. It is intended for users setting up the adapter, restoring an unrecognized interface in Device Manager, or troubleshooting software that cannot access its assigned COM port.

Although listed in the Network category, this interface appears as a serial communication port rather than a standalone network connection. COM18 is the port assignment shown on this system; Windows may assign a different number after installation or when the adapter is connected elsewhere.

Key Features

• Interface recognition: Helps Windows identify the Huawei ETS application interface instead of displaying it as an unknown device.
• COM-port communication: Enables compatible applications to communicate with the adapter through its assigned serial port.
• Legacy Windows support: Listed supported systems include Windows 10, 8.1, 7, Vista, and XP. Select a package that matches your Windows edition and architecture.
• Troubleshooting support: Installing the correct package can help resolve driver-related detection errors or restore an interface after a Windows reinstall.

How to Install Mobile Adapter – ETS Application Interface (COM18) Driver

1. Confirm the device details. Open Device Manager and locate the Huawei interface under Ports (COM & LPT) or Other devices. Check its hardware IDs in Properties to verify that the package matches your adapter.
2. Choose a compatible package. Before starting your Mobile Adapter – ETS Application Interface (COM18) driver download for Windows, confirm OS and 32-bit or 64-bit compatibility. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here.
3. Download and prepare the files. If a free download is available, use a trusted source and check the publisher information. Extract the archive if necessary.
4. Install the driver. Run the included installer, if provided. Otherwise, right-click the interface in Device Manager, select Update driver, and browse to the extracted driver folder.
5. Check the result. Restart if prompted, reconnect the adapter, and confirm that the interface appears without a warning icon. Set your application to the COM port currently shown in Device Manager.

Keep the driver updated when a compatible release addresses a problem you encounter. Choose the latest version verified for your hardware and Windows release, rather than assuming every newer package will work. Before an update, retain the working installer or create a restore point so you can recover if needed.
