Qualcomm Atheros QCA9377 Wireless Network Adapter Driver

The Qualcomm Atheros QCA9377 Wireless Network Adapter driver allows Windows to communicate with your wireless adapter so you can connect to Wi-Fi networks. You may need to install or update it after reinstalling Windows, if the adapter appears as an unknown device, or when troubleshooting dropped connections and missing wireless networks.

Key Features

• Wi-Fi connectivity: Enables Windows to recognize the QCA9377 adapter and use its supported wireless networking capabilities.
• Connection management: Works with Windows network settings to help you discover available networks, connect to your router, and manage wireless connections.
• Compatibility options: Driver packages are available for systems running Windows 11, 10, 8, and 7, though support varies by package and computer manufacturer.
• Maintenance and fixes: An appropriate update may resolve driver-related connectivity problems, improve stability, or address compatibility issues.

How to Install Qualcomm Atheros QCA9377 Wireless Network Adapter Driver

1. Confirm your adapter and Windows version. Open Device Manager and look under Network adapters for the QCA9377. If it appears as an unknown device, check its hardware IDs. Verify your Windows version and whether your system requires a 32-bit or 64-bit package.
2. Choose a compatible download. When selecting a Qualcomm Atheros QCA9377 Wireless Network Adapter driver download for Windows, match the package to your adapter, operating system, and computer model. For Windows 10/11, check the stated compatibility rather than assuming every package supports both.
3. Save and prepare the files. Use a trusted free download, preferably provided by your computer manufacturer, and extract the archive if necessary. If Wi-Fi is unavailable, download the package using Ethernet or another device and transfer it with a USB drive.
4. Install the driver. Run the included installer and follow its prompts. If no installer is provided, open Device Manager, right-click the adapter, select Update driver, then choose Browse my computer for drivers and locate the extracted folder.
5. Restart and test Wi-Fi. Restart your computer if prompted, connect to your wireless network, and check that the adapter appears without a warning icon in Device Manager.

Keep the driver updated by checking Windows Update or your computer manufacturer’s support resources. Choose the latest version approved for your system rather than simply the newest package you find. If an update causes connection problems, use Device Manager’s Roll Back Driver option when available.

Common Issues and Fixes

• Install fails or rolls back: Run the QCA9377 installer as administrator and temporarily pause antivirus. In Device Manager, uninstall the existing wireless adapter and check “Delete the driver software,” then restart and reinstall the matching Windows 10/11 package.
• Device not detected: Check BIOS/UEFI for an enabled Wireless/WLAN radio, then use Device Manager > Scan for hardware changes. Confirm the adapter appears with hardware ID `VEN_168C&DEV_003E`; if not, reseat the M.2 card or test another slot.
• Version conflicts after Windows Update: If Wi-Fi breaks after an update, roll back the driver in Device Manager or uninstall duplicate QCA9377 entries. Prefer the latest Qualcomm/Atheros package or your PC maker’s validated driver, then restart before reconnecting.
