The 3Com 3C460B 10 100 Mbps USB Ethernet Network Adapter provides a wired network connection through a USB port. Its driver allows Windows to recognize the adapter and communicate with it so applications can access local network resources and the internet. Before installing on Windows 11, 10, 8, or 7, confirm that the download supports your exact adapter and Windows version, as compatibility can vary with legacy hardware.

Key Features

• USB Ethernet recognition: Helps Windows identify the 3Com adapter as a network device rather than an unknown USB peripheral.
• 10/100 Mbps networking: Enables communication over compatible Ethernet networks at the adapter’s supported speeds; actual throughput depends on the USB connection and network conditions.
• Windows network integration: Makes the adapter available to Windows networking components for IP configuration, connection status, and standard troubleshooting.
• Driver restoration: A matching driver can restore adapter operation after a Windows reinstall or resolve problems caused by missing or incorrectly installed driver files.

How to Install

1. Check your system and adapter. Confirm that the device label identifies the 3Com 3C460B. Open Windows system information to check your Windows edition and whether it uses a 32-bit or 64-bit architecture.

1. Choose a compatible package. Review the driver’s compatibility information before downloading. Do not assume that a package intended for an older Windows release will work on Windows 11 or Windows 10.

1. Extract and install the files. If the download is compressed, extract it first. Run the included installer, if available, and follow its instructions for when to connect the USB adapter.

1. Use Device Manager if needed. With the adapter connected, locate its entry under Network adapters or Other devices. Select Update driver, choose Browse my computer for drivers, and point Windows to the extracted folder.

1. Verify the connection. Restart if prompted, then connect an Ethernet cable to an active router or switch port. Check that Device Manager shows no warning icon and test access to your network or the internet.

If Windows rejects the driver, look for a package explicitly compatible with your system rather than bypassing driver-signature protections.

Common Issues and Fixes

• Install fails or rolls back: The 3C460B uses a legacy 3Com driver/INF that may be unsigned or incompatible with modern Windows. Run the installer as administrator in Compatibility Mode for XP/2000; if using an INF, temporarily disable driver signature enforcement and install via Device Manager > Have Disk.
• Adapter not detected: Connect the 3C460B directly to a rear USB port, not an unpowered hub. Check Device Manager for an unknown USB Ethernet device or entry under
