Is it for you?
A Wi-Fi 5 dual-band AC1200 USB Type-C adapter with two detachable 5 dBi RP-SMA antennas and the Realtek RTL8812AU chipset, aimed at long-range desktop and laptop Wi-Fi.
Choose it if these matter
- Drivers published for Windows, Linux and macOS through ALFA's download center, including a long-standing Linux driver for the RTL8812AU chipset
Skip it if these rule it out
- Wi-Fi 5 (802.11ac) only: no Wi-Fi 6 or newer radio, so it cannot use OFDMA or 1024-QAM on busy networks
- The Realtek RTL8812AU's out-of-tree Linux driver predates recent kernels, so Linux users may need to build the driver from ALFA's download or community sources
- Bulky on a laptop with both antennas attached, and the screen clip mount is plastic rather than a metal bracket
