The Atheros AR8132 PCI E Fast Ethernet Controller (NDIS 6.20) driver lets Windows communicate with your computer’s built-in wired network adapter. It supports the Ethernet connection used for local network access and internet connectivity through a router or switch. When choosing a download for Windows 11, 10, 8, or 7, check the package’s compatibility details rather than assuming one driver works with every version.

Key Features

• Wired Ethernet connectivity: Enables the AR8132 adapter to send and receive network traffic over an Ethernet cable, with link speeds up to 100 Mbps when supported by the connected equipment.
• Windows networking integration: Connects the controller to the Windows network stack so applications can use the wired connection for browsing, downloads, and shared resources.
• Adapter recognition: Helps Windows identify the Atheros network controller correctly in Device Manager instead of listing it as an unknown Ethernet device.
• Configuration access: Provides access to the adapter settings exposed by the driver, which may include link speed, duplex mode, and power-management options.

How to Install

1. Confirm the hardware 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, and confirm whether your Windows installation is 32-bit or 64-bit.

1. Select a compatible driver package. Choose a download that explicitly supports your AR8132 controller and operating system. The NDIS 6.20 label alone does not establish Windows 10 or Windows 11 compatibility; verify the package information before installing.

1. Prepare the files. Save the download locally and extract it if it comes as an archive. If this computer has no internet connection, download the package on another device and transfer it using a USB drive.

1. Install the driver. Run the included installer, if available. Otherwise, right-click the controller in Device Manager, select Update driver, choose Browse my computer for drivers, and point Windows to the extracted folder. Avoid forcing a driver that Windows identifies as incompatible.

1. Restart and test the connection. Reboot if prompted, connect an Ethernet cable, and check that Device Manager shows no warning icon. If the connection still fails, inspect the cable, router port, and Windows network settings before replacing the driver again.

Common Issues and Fixes

• Install fails or rolls back: The Atheros AR8132 NDIS 6.20 package can fail if an older Atheros/Qualcomm LAN driver is present or the installer is not run as administrator. Uninstall the existing Ethernet device in Device Manager with “Delete the driver software,” reboot, then run the correct 32/64-bit installer as administrator.
• Device not detected (Code 10/28): Confirm onboard LAN is enabled in BIOS or reseat the PCIe card. In Device Manager, scan for hardware changes and check for the Atheros PCI vendor/device ID. If missing, install manually via Update Driver > Browse > Pick from a list > Network adapters.
• Version conflicts or link drops: Windows Update may replace the NDIS 6.20 driver with a generic Atheros/Qualcomm version. Use Roll Back Driver or reinstall the matching AR8132 package, and temporarily pause automatic driver updates.
