The Corechips RD9700 USB2.0 To Fast Ethernet Adapter provides a wired network connection through a USB port. Its driver allows Windows to recognize the adapter and communicate with it, helping resolve issues such as an unidentified USB device or a missing Ethernet connection.

Key Features

• Device recognition: Enables Windows to identify the Corechips RD9700 adapter as a network device rather than an unknown USB peripheral.
• Wired networking support: Provides the software interface needed to send and receive network traffic through the adapter’s Ethernet port.
• Windows network integration: Lets you manage the connection through standard Windows networking tools, including IP address and DNS settings.
• Driver management: Supports installation and troubleshooting through Device Manager, where you can check device status and review the installed driver.

How to Install

1. Check your Windows version. Before downloading, confirm whether your PC runs Windows 11, 10, 8, or 7, and check its system type. Choose a driver package that explicitly supports your Windows version and architecture; older RD9700 packages may not work on newer systems.

1. Download and extract the driver. Save the appropriate Corechips driver package to your computer. If it comes in a compressed archive, extract it to a folder you can easily locate.

1. Connect the adapter. Plug the adapter into an available USB port and attach an Ethernet cable connected to your router or network switch.

1. Install the software. Run the supplied installer if one is included. Otherwise, open Device Manager, locate the adapter under Network adapters or Other devices, select Update driver, and browse to the extracted driver folder.

1. Verify the connection. Restart your PC if prompted, then check the adapter’s status in Device Manager and confirm that Windows detects the Ethernet connection.

If installation fails, compare the adapter’s hardware IDs in Device Manager with those supported by the driver package. Similar-looking USB Ethernet adapters can use different chipsets, so matching the hardware is more reliable than choosing a driver by appearance alone.

Common Issues and Fixes

• Install fails or is blocked: Run the RD9700 installer as administrator and match the driver package to your Windows version/architecture. If Windows blocks it, temporarily disable driver signature enforcement, install, then re-enable it.
• Adapter not detected: Use a direct USB 2.0 port instead of a hub. Check Device Manager for “Unknown Device” or a network adapter entry, unplug/replug, scan for hardware changes, and update the driver manually via “Browse my computer.”
• Version conflicts: Uninstall any existing RD9700/USB Ethernet driver, select “Delete the driver software,” reboot, then install only the Corechips RD9700 package. Prevent Windows Update from silently replacing it if connectivity breaks.
