Product Overview
#The AWUS036EACS is Alfa’s ultra-compact WiFi + Bluetooth combination adapter, designed for home and office users who want both wireless connectivity in a single discreet USB dongle. Built around the Realtek RTL8821CU chipset, it integrates AC600 dual-band WiFi and Bluetooth 4.2 in a nano form factor with built-in driver support on Windows. Its Soft AP mode lets you share your internet connection. This adapter prioritises simplicity and compactness over performance — it is NOT recommended for Linux power users, Kali Linux, or security research.
⚠️ Note: AWUS036EACS is designed for Windows home use. RTL8821CU has poor Linux community driver support. NOT recommended for Linux, Kali Linux, or Raspberry Pi. No RP-SMA port — antenna is non-upgradeable.
