When searching for a driver, be very careful about the source. Stick to official manufacturer websites. Many third-party download sites trick you into downloading "Driver Update Tools" that are often bundled with unwanted adware or other software. While these tools sometimes work, they are a major security risk. It's always best to find the driver yourself from a trusted source.

Finding the correct driver for Windows 10 depends on whether you are using the older PCI cards or integrated PCIe controllers.

Realtek discontinued official, dedicated Windows 10 driver development for the original RTL8139 series years ago. If you cannot find a native Windows 10 driver, the Windows 7 or Windows 8 driver package will work perfectly.

The RTL8139 and 810x chips are physically incapable of achieving Gigabit speeds. If your motherboard specification sheets claim you have a Gigabit port, you actually have a chip from the RTL8111 or RTL8168 family, and you will need the driver instead. If your hardware truly is an RTL8139 or an 810x family chip, it is a Fast Ethernet adapter designed for a maximum cap of 100 Mbps. Why Windows 10 Struggles with Legacy Realtek Drivers
