Alfa AWUS 036 ARCH
Dual-band 802.11ac USB Wi‑Fi adapter with twin high-gain antennas — built for range, Kali Linux, and everyday dual-band connectivity.
The Alfa AWUS036ACH is a dual-band 802.11ac USB Wi‑Fi adapter designed for long-range reception and reliable wireless performance. It uses the RTL8812AU chipset and delivers AC1200 speeds: up to 300 Mbps on 2.4 GHz and up to 867 Mbps on 5 GHz.
Two detachable high-gain antennas (RP-SMA) help you pull in weaker signals and can be swapped for directional panels when you need more reach. A USB 3.0 connection keeps throughput high, and the adapter is widely used with Kali Linux for monitor mode and packet injection, as well as for general dual-band networking on supported operating systems.
Ideal if you need a rugged, external Wi‑Fi adapter that outperforms most built-in laptop cards — whether you’re auditing networks, working at the edge of coverage, or just want a stronger dual-band link.
