The 3Com EtherLink Server 10 100 PCI (3C980C TXM) driver allows Windows to communicate with this PCI Ethernet adapter and use it for a wired network connection. A compatible driver helps the operating system identify the card and manage network traffic over its 10/100 Mbps Ethernet interface.

Key Features

• Device recognition: Identifies the 3Com network adapter in Windows so the operating system can access its networking functions.
• Wired Ethernet connectivity: Supports communication on compatible 10 Mbps and 100 Mbps networks for local resource access and internet connectivity.
• Network configuration: Works with Windows networking settings to let you configure TCP/IP, address assignment, and other connection options.
• Adapter status and troubleshooting: Makes device information and driver status available through Device Manager, helping you investigate detection or connection problems.

This is a legacy PCI adapter. Before downloading a driver for Windows 11, 10, 8, or 7, check the package documentation for explicit support for your Windows version and system architecture. Compatibility with these operating systems should not be assumed, especially on 64-bit systems.

How to Install

1. Confirm the hardware and Windows version. Open Device Manager and locate the adapter under Network adapters or Other devices. If its name is unclear, check its hardware IDs in Properties. Also confirm whether Windows is 32-bit or 64-bit.
2. Select a compatible package. Verify that the download lists the 3Com EtherLink Server 10 100 PCI (3C980C TXM), or its matching hardware ID, and supports your operating system.
3. Extract and install the driver. Run the included installer if provided. Otherwise, right-click the adapter in Device Manager, select Update driver, and browse to the extracted driver folder.
4. Restart if prompted. After installation, check that the adapter appears without a warning icon. If Windows rejects the driver as incompatible or unsigned, do not force installation or disable security protections.
5. Test the connection. Attach an Ethernet cable to a working router or switch, then check Windows network status and try accessing a network resource. If no supported driver is available, consider a newer Ethernet adapter with documented Windows support.

Common Issues and Fixes

• Install fails or driver is blocked: The 3C980C-TXM package is legacy and may be unsigned on newer Windows. Run setup as administrator, use compatibility mode for the original OS, or update manually via Device Manager using the extracted INF file.
• Device not detected: Power off, reseat the PCI card, try another 32-bit PCI slot, and confirm the slot/IRQ is enabled in BIOS. Check the adapter’s link LED after boot.
• Version conflict with built-in/generic NIC driver: In Device Manager, uninstall the existing 3Com or generic adapter and select “Delete driver software,” then install the 3C980C-TXM driver before rebooting.
