The Davicom DM9601 USB To Fast Ethernet Adapter adds a wired network connection through a USB port. Its driver allows Windows to recognize the adapter and exchange data over Ethernet, making it useful for a computer without a working built-in network port.

Key Features

• USB-to-Ethernet communication: Enables Windows to communicate with the Davicom DM9601 controller so the adapter can connect to a wired local network.
• Network adapter integration: Makes the device available through Windows networking settings, where you can configure IP addressing, check connection status, and troubleshoot connectivity.
• Fast Ethernet connectivity: Supports the adapter’s Ethernet functions for everyday tasks such as browsing, accessing shared folders, and connecting to network printers. Actual performance depends on the USB connection, network equipment, and adapter hardware.
• Driver identification and management: With a compatible package installed, Device Manager can identify the adapter and provide access to driver details, updates, and rollback options.

How to Install

1. Confirm the adapter and Windows version. Connect the adapter to a USB port and open Device Manager. If it appears as an unknown device, check its Hardware IDs under Properties > Details to help confirm that the driver matches the hardware.

1. Choose a compatible driver package. For Windows 11, Windows 10, Windows 8, or Windows 7, verify that the download explicitly supports your operating system and system architecture. The DM9601 is an older controller, so do not assume that every driver package supports all four Windows versions.

1. Extract and install the driver. If the download is compressed, extract it first. Run the included installer if available. Otherwise, right-click the adapter in Device Manager, select Update driver, choose the option to browse your computer, and select the extracted driver folder.

1. Complete setup and reconnect if needed. Follow the installation prompts and restart Windows if requested. If Windows reports an incompatible or unsigned driver, look for a suitable signed package rather than disabling security protections.

1. Test the wired connection. Attach an Ethernet cable between the adapter and your router or switch. Check that Device Manager shows no warning icon, then confirm that Windows detects the network. If there is no connection, try another cable or USB port and review your network settings.

Common Issues and Fixes

• Install fails or driver is rejected: The DM9601 often uses older unsigned or 32/64-bit-mismatched packages. Download the correct architecture, extract it, and update manually via Device Manager → Network adapters → Update driver → Browse. Run setup as administrator.
• Device not detected: Try a rear USB port directly on the PC, replace the cable, and avoid unpowered hubs. Check Device Manager for an unknown USB device or “Davicom DM9601” under Network adapters; if absent, test the adapter on another PC.
• Version conflicts or unstable connection: Windows may already load a generic USB Ethernet driver. Uninstall any existing DM9601 driver, reboot, then install one version only. If a new driver breaks connectivity, roll back in Device Manager.
