Finding the right driver for a Corechip Semiconductor USB to Ethernet adapter can be a bit of a hunt, especially since many of these devices are unbranded or "generic" imports. If you’ve upgraded to Windows 11 and your reliable internet adapter has suddenly gone dark, you aren't alone.
Here is a guide on how to locate, install, and troubleshoot Corechip drivers for the latest version of Windows. The Challenge with Corechip Drivers
Corechip (often identified as the RD9700 or SR9900 chipset) is a popular, budget-friendly solution for adding Ethernet ports to laptops. However, because Windows 11 has stricter driver signature requirements, older drivers that worked on Windows 7 or 10 often fail to initialize. Step 1: Identify Your Specific Chipset
Before downloading anything, you need to know exactly which "Corechip" you have. Right-click the Start button and select Device Manager Other Devices Network Adapters
Right-click the "USB 2.0 10/100M Ethernet Adaptor" (or similar name) and select Properties tab and select Hardware Ids from the dropdown. Look for the (Vendor ID) and (Product ID). VID_0FE6 & PID_9700: This is the common RD9700 chipset. VID_0B95 & PID_7720: Often associated with ASIX or upgraded Corechip models. Step 2: Where to Find Windows 11 Drivers
Windows 11 will often attempt to find a driver automatically, but it frequently fails with Corechip devices. 1. Windows Update (The "Optional" Path)
Settings > Windows Update > Advanced options > Optional updates
. Check under "Driver updates." Often, a compatible ASIX or Corechip driver is tucked away here. 2. Manufacturer Repositories
Since Corechip doesn't always maintain a consumer-facing website, many users rely on the Microsoft Update Catalog
. Search the catalog for "RD9700" or "SR9900." Look for drivers labeled for "Windows 10, Windows 11, and later." 3. Realtek/ASIX Cross-Compatibility
Many Corechip adapters are clones of ASIX or Realtek designs. If the Hardware ID matches an ASIX 88772 chipset, downloading the official driver from the ASIX website is actually safer and more stable than using a generic "Corechip" file from a random forum. Step 3: Installation Tips for Windows 11
If the driver installer (.exe) doesn't work, try a manual forced install: Extract the driver folder (if it's a .zip or .rar). Device Manager , right-click the device > Update driver Browse my computer for drivers Let me pick from a list of available drivers on my computer and navigate to the folder containing the Troubleshooting Common Issues "Device cannot start (Code 10)":
This usually means the driver is incompatible with Windows 11's memory integrity settings. Try turning off Core Isolation
in Windows Security, though this is not recommended for long-term safety. Slow Speeds:
Most Corechip RD9700 adapters are limited to USB 2.0 speeds (around 5–10 Mbps in practice). If you have high-speed fiber internet, the adapter itself might be the bottleneck, not the driver. Frequent Disconnects:
Disable "Allow the computer to turn off this device to save power" in the Power Management tab of the device properties. Final Verdict: Is it time to upgrade?
Corechip RD9700 adapters were designed for an era of much slower internet. If you are struggling with drivers on Windows 11, it might be worth investing in a USB 3.0 Gigabit adapter
(using a Realtek RTL8153 or ASIX AX88179 chipset). These are natively supported by Windows 11, requiring zero manual driver installation. Hardware ID (the VID and PID) from Device Manager? Is your Windows 11 the Home, Pro, or S Mode Is the device showing a yellow exclamation mark or is it not showing up at all? Let me know those specs and I can find the direct download link for the most stable driver!
