The Realtek RTL8188EU is a single-chip 802.11n USB Wi‑Fi solution commonly used in low-cost USB wireless adapters. It supports IEEE 802.11b/g/n (2.4 GHz), up to 150 Mbps PHY rate (single spatial stream), USB 2.0, and basic power-management and security features (WPA/WPA2). Because vendor-provided drivers for Linux/other OSes are sometimes missing or outdated, community-driven or out-of-tree drivers are frequently used.
Most of these are solved by the right driver version, not necessarily the latest . The Realtek RTL8188EU is a single-chip 802
