- For older RTL8139 PCI (10/100) adapters, use legacy RTL8139 drivers; modern "RTL810x/811x" packages may not support legacy 8139 without separate legacy driver.
- Windows Update may supply a built-in driver; if experiencing issues, manually install Realtek’s latest driver.
- For systems with multiple Realtek versions, remove old drivers via Device Manager (Uninstall device → delete driver software) before installing a new package to avoid conflicts.
- Disable power management (Device Manager → Properties → Power Management) if the NIC intermittently disconnects.
- If driver fails to install due to signature enforcement on 64-bit Windows, temporarily disable driver signature enforcement or use a signed driver from the vendor.
