Qualcomm Atheros AR8152 8158 PCI E Fast Ethernet Controller (NDIS 6.20) Driver

The Qualcomm Atheros AR8152 8158 PCI E Fast Ethernet Controller (NDIS 6.20) driver allows Windows to communicate with this QualComm wired network adapter and use its Ethernet connection. You may need it after reinstalling Windows, when Device Manager lists an unknown network controller, or when a missing or incompatible driver prevents wired internet access.

Key Features

• Enables wired networking through the compatible PCI Express Fast Ethernet controller, supporting connections up to 100 Mbps when the network equipment and cable allow.
• Provides the driver interface Windows needs to recognize and manage the adapter.
• Supports everyday local network and internet tasks, including browsing, file transfers, and access to shared printers.
• Can help resolve connection problems caused by missing, damaged, or incompatible driver files, though it cannot fix faulty cables or network equipment.

How to Install Qualcomm Atheros AR8152 8158 PCI E Fast Ethernet Controller (NDIS 6.20) Driver

1. Confirm your adapter and Windows version. Open Device Manager and look under Network adapters or Other devices. Check the controller’s hardware IDs if its name is unclear, then confirm whether your Windows installation is 32-bit or 64-bit.
2. Choose a compatible package. Before starting your Qualcomm Atheros AR8152 8158 PCI E Fast Ethernet Controller (NDIS 6.20) driver download for Windows, review the package’s supported systems. For Windows 11, 10, 8, or 7, choose a release explicitly compatible with your setup; the NDIS 6.20 label alone does not establish Windows 10/11 compatibility.
3. Download and prepare the files. Use a trusted free download source, preferably your computer manufacturer’s support page. Extract the archive if necessary. If Ethernet is unavailable, download on another device and transfer the files using a USB drive.
4. Install the driver. Run the included installer, or right-click the controller in Device Manager, select Update driver, and choose Browse my computer for drivers. Point Windows to the extracted folder and follow the prompts.
5. Restart and test. Restart if requested, connect your Ethernet cable, and confirm that the adapter appears without a warning icon. Test access to the internet or a local network resource.

Keep the driver updated when a compatible release addresses a problem or improves reliability. Check the latest version against your hardware and operating system before you update; a newer package is not automatically the right choice for an older controller. If your connection is stable, avoid replacing a working driver without a clear reason.

Common Issues and Fixes

• Install fails or rolls back: The AR8152/8158 driver package is old and may be unsigned on newer Windows. Extract the ZIP, then use Device Manager > Network adapters > Update driver > Browse and select the folder with the `.inf`. Run setup as administrator; if blocked, use a signed OEM build or temporarily disable signature enforcement.
• Device not detected / Code 10 or 28: Enable onboard LAN in BIOS/UEFI and rescan hardware. Confirm the adapter shows under Unknown/Other devices and its Hardware IDs match `VEN_1969&DEV_2060` or `DEV_2062`. If missing, the PCIe LAN function is disabled or faulty.
• Version conflicts: Uninstall old Atheros/Qualcomm drivers and third-party network utilities, reboot, then install the matching AR8152/8158 NDIS 6.20 package. Do not force an AR8151 Gigabit driver; it will not bind correctly.
