Alfa Network is a well-known brand specializing in long-range wireless networking equipment, particularly USB Wi-Fi adapters (e.g., Alfa AWUS036 series). These adapters are popular among cybersecurity professionals, ethical hackers, and enthusiasts for packet injection, monitor mode, and high-gain antenna support. A critical requirement for proper operation is the correct driver installation.

Standard Realtek drivers from the Realtek website are usually insufficient for penetration testing. The community has created patched drivers.
