Excellent for legacy systems (Windows XP to 11) and widely supported by Linux kernels, making it a favorite for Raspberry Pi 2B HAOYU Electronics Pros and Cons
Because this is a device utilizing 1T1R architecture, you should not expect blazing-fast gigabit speeds. The theoretical maximum is 150 Mbps, but in real-world scenarios (due to protocol overhead and interference), you are more likely to see sustained transfers between 40 Mbps and 70 Mbps. Excellent for legacy systems (Windows XP to 11)
Conclusion The RTL8188CU is a cost‑effective solution for basic Wi‑Fi needs on a USB port, but its modest single‑stream 2.4 GHz design and variable driver quality mean you may need to tune placement, drivers, and power settings for reliable performance. For higher throughput, range, or 5 GHz support, choose a more modern multi‑stream adapter. For higher throughput, range, or 5 GHz support,
Realtek removed the RTL8188CU from its main site, but legacy drivers work perfectly. It was a Realtek RTL8188CU Wireless LAN 802
