Cause: IP address conflict or driver mismatch. Fix:

Yes, for specific use cases:

No, if you:

This is where most users fail. Apple removed native support for many generic chipsets after macOS Catalina (10.15).

For macOS Ventura, Sonoma, or Sequoia:

  • Alternatively, buy a licensed driver from mac-usb-ethernet.com (supports SR9900).
  • Easier solution: If you run macOS, replace the adapter. A Chipset based on Realtek RTL8153 (Gigabit) works without drivers on macOS.

    Linux

  • If your kernel is recent, plug-and-play usually works. If not:
  • For persistent issues, try updating the kernel or use the r8152 driver from the kernel rather than older vendor blobs.
  • Windows

  • If Windows installs a generic driver with limited performance, use the vendor-supplied driver to restore full features (e.g., gigabit support, proper power management).
  • macOS

  • For Big Sur and newer, driver compatibility is more restrictive; prefer adapters explicitly listed as macOS-compatible.
