Realtek Rtl8188cu Wireless — Lan 802.11n Driver Windows 10 64 Bit ((full))

The Ultimate Guide to the Realtek RTL8188CU Wireless LAN 802.11n Driver for Windows 10 64 Bit

Method 2: The Manual Driver Install (Most Reliable)

If Windows Update fails, you must manually install the driver. Since Realtek changes their website frequently, it is often easier to use the drivers provided by manufacturers who use this chip (like TP-Link) or trusted driver repositories.

Option 1: Realtek’s Official (But Buried) Driver

Realtek never released a dedicated “Windows 10 64-bit” driver for the 8188CU. Instead, the Windows 8.1 driver (which uses a later NDIS version) works. The official file is typically named:

Realtek does not host consumer-facing drivers directly, but they provide OEM drivers through their customer support portal. Alternatively, use Realtek’s official download center: Latest functional version: 1030
