Is it for you?
A Wi-Fi 5 dual-band AC1200 USB 3.0 Type-A adapter with two detachable 5 dBi RP-SMA antennas and the MediaTek MT7612U chipset, a chipset known for strong Linux support.
Choose it if these matter
- MediaTek MT7612U chipset is supported in the mainline Linux kernel, so it generally works out of the box on Linux without a vendor driver
- ALFA publishes Windows, macOS and Linux drivers, a quick start guide and a datasheet on its support site, unusually full documentation for a USB adapter
Skip it if these rule it out
- Wi-Fi 5 (802.11ac) only: no Wi-Fi 6 or newer radio
- Windows driver support tops out at Windows 10 per the spec sheet, and the maker lists no Windows 11 driver
- 23 dBm output is the maker's rated maximum; actual permitted power depends on your region's regulations
