USB 3.0 AC1200 dual-band Wi-Fi adapter

The SMA USB 3.0 Wi-Fi adapter connects a desktop, laptop or tablet to 2.4 GHz and 5.8 GHz networks at up to 1200 Mbps. It uses a USB 3.0 interface and a dual-band 5 dBi antenna. The package includes the dongle, a driver CD and a user manual.

Buyers who need a simple speed boost on Windows.

This adapter suits users wanting faster wireless performance without opening their device. It is not for systems that lack a USB 3.0 port or for buyers who need an internal PCIe card with external antennas.

USB 3.0 interface with RTL8812BU chip

The adapter requires a USB 3.0 port for full throughput and uses the RTL8812BU chipset supporting IEEE 802.11ac/a/n/g/b. Windows 10 works plug-and-play; other operating systems need the supplied driver installed first.

Questions about this item

What comes in the box and do I need to buy anything extra to use the SMA AC1200 USB 3.0 Wi-Fi adapter?

The package includes the wireless USB dongle, a user manual and a CD driver. No additional hardware is required; simply install the driver from the disc or download it, then plug the adapter into a free USB 3.0 port.

Should I choose the 2.4 GHz or 5.8 GHz band on this dual-band adapter for the best speed?

The 5.8 GHz band delivers up to 867 Mbps, while the 2.4 GHz band reaches 300 Mbps. Select 5.8 GHz for higher throughput when the signal is strong, or 2.4 GHz for better range through walls.

What does the 1200 Mbps rating mean once the adapter is connected to my desktop?

The 1200 Mbps figure combines the maximum 867 Mbps on 5.8 GHz and 300 Mbps on 2.4 GHz. Actual throughput depends on router capabilities, distance, interference and the USB 3.0 host controller.
