The ASIX AX88772B USB2.0 to Fast Ethernet Adapter provides a wired network connection through a USB port. Its driver allows Windows to recognize the adapter and use it for Ethernet access, making it useful for computers without a built-in network socket or with a faulty Ethernet port.

Key Features

• USB-to-Ethernet connectivity: Enables Windows to communicate with the ASIX AX88772B chipset and use the adapter as a wired network interface.
• Fast Ethernet support: Supports 10/100 Mbps Ethernet connections over USB 2.0. Actual transfer speeds depend on your network equipment, connection quality, and other conditions.
• Windows network integration: Makes the adapter available through standard Windows networking tools for checking connection status and configuring IP settings.
• Support across Windows versions: Driver packages are available for Windows 11, 10, 8, and 7. Choose a package that explicitly matches your operating system and system architecture.

How to Install

1. Check your Windows version. Open your system information to confirm the Windows edition and architecture. Select a driver package that lists both your operating system and the ASIX AX88772B chipset.
2. Download and extract the driver. Save the compatible package to your computer. If it comes in a compressed archive, extract its contents before starting installation. Without a working internet connection, download it on another computer and transfer it using a USB drive.
3. Run the installer, if included. Follow the on-screen instructions and connect the adapter when prompted. If no installer is supplied, plug in the adapter and open Device Manager.
4. Install manually when needed. Locate the adapter under Network adapters or Other devices, right-click it, and select Update driver. Choose the option to browse your computer, then point Windows to the extracted driver folder.
5. Verify the connection. Restart if requested, connect an Ethernet cable between the adapter and your router or switch, and check that Windows reports a network connection. Confirm that Device Manager shows the adapter without a warning icon.

If the adapter remains unrecognized, try another USB port and recheck the driver’s compatibility. A disconnected Ethernet cable or inactive router port can prevent network access even when the driver is installed correctly.

Common Issues and Fixes

• Install fails or driver is blocked: Windows may reject the ASIX package if an older AX88772B driver is already installed. In Device Manager, uninstall the existing adapter driver (check “Delete the driver software”), reboot, then run the ASIX installer as administrator.
• Adapter not detected: Try a different USB 2.0 port directly on the PC, avoid unpowered hubs, and check Device Manager for unknown/USB device errors. Reconnect the adapter and rescan for hardware changes.
• Version conflicts or intermittent drops: Windows Update may install a generic ASIX/USB Ethernet driver over the vendor package. Set the ASIX driver explicitly, roll back if needed, and disable power management on the adapter’s USB root hub.
