Preliminary Steps: Preparation for the Fix

Before applying any fix, perform these checks:

| Step | Action | Why? | |------|--------|------| | 1 | Create a System Restore point | Allows rollback if something goes wrong | | 2 | Disable antivirus temporarily | Some AVs block self-extracting executables | | 3 | Pause Windows Updates (Settings > Windows Update > Pause for 7 days) | Prevents automatic driver overwrite | | 4 | Download the latest official driver | Do not rely on old copies of rtknicdriverinstallersfxexe |

Critical: Obtain the latest Realtek driver directly from your motherboard manufacturer’s support page or from Realtek’s official site (Realtek PCIe FE / GbE / 2.5G / Gaming Ethernet Family Controller Software). Press Win + R , type msconfig , and press Enter

  3. Extract the ZIP to a folder (e.g., C:\Realtek_Manual).
  4. Inside, look for a subfolder named Win11 or NDIS – you will find .inf files.
  5. Open Device Manager → Network adapters → Right-click Realtek → Update driver.
