Huawei EM680 w/Gobi Technology-Modem (COM4) Driver

The Huawei EM680 w/Gobi Technology-Modem (COM4) driver helps Windows recognize the modem interface and allows compatible connection software to communicate with the device. This Qualcomm Atheros USB-category driver is intended for users setting up the modem, restoring it after a Windows reinstall, or troubleshooting a missing modem interface in Device Manager.

Key Features

• Modem interface recognition: Helps Windows identify the Huawei EM680 modem component and make it available to compatible applications.
• Serial-port communication: Supports communication through the modem’s assigned COM port. Although the device name includes COM4, Windows may assign a different port on another system.
• Legacy Windows compatibility: Listed operating systems include Windows 10, Windows 8.1, Windows 7, Windows Vista, and Windows XP; choose a package that explicitly matches your system.
• Connection-software support: Provides the driver interface used by compatible mobile broadband utilities. Network access still depends on the appropriate software, service, and device configuration.

How to Install Huawei EM680 w/Gobi Technology-Modem (COM4) Driver

1. Check your Windows version and architecture. Confirm whether your system uses 32-bit or 64-bit Windows. For Windows 10/11 systems, note that Windows 10 is listed as supported, while Windows 11 compatibility is not confirmed.
2. Verify the device. Open Device Manager, locate the modem or unidentified USB device, and check its hardware IDs under Properties > Details. Match these against the driver package’s supported devices rather than relying only on the COM4 label.
3. Select the correct package. Before starting your Huawei EM680 w/Gobi Technology-Modem (COM4) driver download for Windows, confirm the package source, supported operating systems, and hardware match. A free download should not require unrelated utilities.
4. Install the driver. Extract the downloaded archive if necessary, then run its included installer. If no installer is provided, use Device Manager’s Update driver option and browse to the extracted driver folder.
5. Restart and verify. Restart Windows if prompted, then check that the modem appears without a warning icon in Device Manager. Open your compatible connection software to confirm that it detects the modem.

Keep a copy of the working driver before you update. Choose the latest version that explicitly supports your hardware and Windows release, rather than assuming a newer package will work better. If an update causes detection or connection problems, use Device Manager’s Roll Back Driver option when available.
