Do not expect miracles. The Realtek RTL8188CU is a single-stream, 150 Mbps chip. On Windows 10 64-bit with a good driver:
If you need reliable 100+ Mbps or 5 GHz support, consider upgrading to a modern chipset like Realtek RTL8812AU (AC1200) or MediaTek MT7612U.
Many generic RTL8188CU adapters work perfectly with the drivers from the TP-Link TL-WN722N (Version 1), which uses the exact same chip.
If you cannot find any working driver, use the Microsoft Update Catalog:
Warning: Avoid generic “driver updater” software. Most are adware or provide unsigned drivers that break your system.
The TP-Link TL-WN722N V1 driver is your best bet for a generic RTL8188CU device on Windows 10 64-bit because TP-Link maintains their download servers better than Realtek does. Always download the ZIP version if possible so you can manually point Device Manager to it if the automatic installer fails.
