SMA AC650 USB 3.0 Adapter

The SMA AC650 is a USB 3.0 wireless adapter delivering Wi-Fi 5 dual-band connectivity at up to 650Mbps. It adds 2.4 GHz and 5.8 GHz wireless networking to desktops and laptops running Windows XP through Windows 11. A 5dBi high-gain external antenna provides stronger signal penetration than internal alternatives. The compact black dongle measures 171 by 37 by 12 mm and weighs 40g.

Suits PCs lacking built-in Wi-Fi

This adapter suits users who need to add wireless networking to a desktop or upgrade an older laptop without opening the case. Driverless installation on Windows 10 and 11 makes it a quick plug-and-play solution. It is not for buyers who require Bluetooth connectivity, as the device has no Bluetooth support. It also does not suit systems that only offer USB 2.0 ports if maximum throughput is expected, because the adapter uses a USB 3.0 interface.

Fits a USB 3.0 port and frees PCIe slots

The adapter plugs into any USB 3.0 Type-A port and draws power from the bus, so no internal power cables or PCIe slots are needed. Its adjustable antenna rotates 180 degrees front to back and 90 degrees side to side for optimal positioning. MU-MIMO support lets the adapter share router capacity efficiently when multiple devices are active. WPA-PSK, WPA2-PSK and WEP encryption are supported for network security.

Questions about this item

Does this adapter need a USB 3.0 port on my computer to reach its 650 Mbps rate?

It connects via a USB 3.0 interface and delivers up to 200 Mbps on 2.4 GHz and 433 Mbps on 5 GHz. A USB 2.0 port will limit throughput below those figures.

Will it work with my existing Wi-Fi 4 router on the 2.4 GHz band?

Yes. The adapter supports Wi-Fi 5 and is backward compatible, so it will connect to a Wi-Fi 4 router at 2.4 GHz using WPA-PSK, WPA2-PSK or WEP encryption.

How can I confirm the 5 dBi antenna is improving my signal after installation?

Rotate the antenna through its 180 ° front and 90 ° side range while watching the signal-strength meter in Windows; the position showing the highest reading is the optimal orientation.
