Supported hardware IDs (41)

Compare with your device: Device Manager → right-click the device → Properties → Details → Hardware Ids. If one of the values above matches, this driver supports your hardware.

How to install

Before you start: create a restore point (Start → type "Create a restore point" → Create). It takes a minute and lets you undo everything if the new driver turns out worse than the old one. This driver is made for Windows 11 (64-bit) - if your Windows is different, look for another version further down the page.

This driver comes as a .cab file. Double-clicking it will not install anything - Windows only shows you what is inside. Install it through Device Manager instead:

  1. Right-click the downloaded file → Extract All → choose a folder you will not lose (the Desktop is fine) → Extract.
  2. Hold the Windows key and press X, then open Device Manager.
  3. Find the device that is not working - it usually has a yellow triangle, or sits under "Other devices" with a name like "Network controller".
  4. Right-click it → Update driver→ "Browse my computer for drivers".
  5. Click Browse, choose the folder you extracted into, tick Include subfolders, then Next.
  6. Windows finds the driver in that folder and installs it. Restart the computer afterwards.

If Windows answers "The best drivers for your device are already installed" - that does not mean your driver is fine, only that Windows prefers its own version. In the same window choose "Let me pick from a list of available drivers" → "Have Disk" → Browse → point to the file ending in .inf inside the extracted folder → OK.

Check it worked: open Device Manager again. The device should no longer show a warning icon, and its driver version should match the one on this page.

How to roll back

If the device stops working after the update: Device Manager → right-click the device → Properties → Driver tab → Roll Back Driver. If that button is greyed out, use the restore point you made before installing (Start → "Recovery" → Open System Restore).
