For a headless setup, the default driver crashes under load. Fix it via terminal:
sudo apt update
sudo apt install git dkms raspberrypi-kernel-headers
git clone https://github.com/aircrack-ng/rtl8188eus
cd rtl8188eus
sudo ./install.sh
sudo reboot
After reboot, verify with lsmod | grep 8188eu. (Do not copy verbatim from proprietary sources; write

Key functions of the RTL8188EU driver include: After reboot, verify with lsmod | grep 8188eu
This is the most common complaint with the RTL8188EU.
Windows 8, 10, and 11 will automatically fetch a driver via Windows Update. However, Microsoft often pushes a generic "USB 802.11n Adapter" driver (sometimes labeled as RTL8192cu). While this driver gets you online, it is notorious for: The driver acts as the translator between the
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 Because vendor-provided drivers for Linux/other OSes are sometimes missing or outdated, community-driven or out-of-tree drivers are frequently used.
