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.
