The ASIX AX88772 USB2.0 to Fast Ethernet Adapter adds a wired network connection through a USB port. Its driver allows Windows to recognize the adapter and communicate with it, enabling Ethernet access for internet browsing, local network resources, and file transfers. When downloading a driver for Windows 11, 10, 8, or 7, choose a package that explicitly supports your Windows version and system architecture.

Key Features

• USB Ethernet support: Enables Windows to use the ASIX AX88772 adapter as a wired network interface over USB 2.0.
• Fast Ethernet connectivity: Supports 10/100 Mbps Ethernet connections, with actual speeds depending on your network equipment, connection, and workload.
• Windows network integration: Makes the adapter available through standard Windows networking tools so you can configure IP settings and check connection status.
• Hardware communication: Provides the software interface needed for data transfer between the USB adapter and the Windows networking system.

How to Install

1. Check your Windows version and architecture. Open your system information to confirm whether you use Windows 11, 10, 8, or 7 and whether your installation is 32-bit or 64-bit. Select an ASIX AX88772 driver package that matches both.

1. Download and extract the driver. Save the compatible package to an accessible folder. If it comes as a compressed archive, extract its contents before starting installation.

1. Run the installer, if included. Follow the on-screen instructions and connect the adapter when prompted. You may need administrator permission to complete the process.

1. Use Device Manager if there is no installer. Connect the adapter, open Device Manager, and locate it under Network adapters or Other devices. Right-click the device, select Update driver, then choose Browse my computer for drivers and point Windows to the extracted folder.

1. Verify the connection. Restart Windows if requested, then connect an Ethernet cable between the adapter and your router or network switch. Confirm that the adapter appears without a warning icon in Device Manager and test access to your network.

If Windows does not recognize the adapter, try another USB port and verify its hardware ID before installing a different package. Similar adapter names can refer to different chipsets, so matching the driver to the actual hardware is important.

Common Issues and Fixes

• Install fails or adapter shows a warning in Device Manager: Use the ASIX driver package matching your Windows version and architecture, and run the installer as administrator. If setup still fails, update the driver manually via Device Manager → Update driver → Browse → select the extracted INF folder. Check the hardware ID `USBVID_0B95&PID_7720` to confirm the correct device.
• Adapter not detected: Try a different USB 2.0 port directly on the PC, not a hub. Confirm the adapter’s link LED and Ethernet cable. In Device Manager, uninstall the device and rescan; also disable USB selective suspend for the root hub.
• Driver version conflicts: Windows Update may install a generic ASIX driver over the vendor package. Uninstall the old driver and delete its driver package, then reinstall the correct ASIX version and prevent automatic replacement if needed.
