AC1200 Dual Band USB 3.0 Adapter

This USB 3.0 wireless adapter adds AC1200 dual band Wi-Fi to desktops and laptops. It connects on 2.4 GHz or 5 GHz bands with two 5 dBi antennas for extended range. The device supports Windows from XP through 10 and macOS 10.6 to 10.13. No CD is required for driver installation.

USB 2.0 Adapter Upgrade

Replacing a USB 2.0 wireless adapter removes the 10 times slower bus bottleneck and lets the AC1200 radio reach its rated throughput. The jump is worth it when your router supports 5 GHz and you need up to 867 Mbps on that band or 400 Mbps on 2.4 GHz. MU-MIMO capability also improves efficiency with a compatible router.

Desktop and Laptop Users

Suits users who want plug and play Wi-Fi on Windows or Mac without internal card installation. The dual antennas help in rooms far from the router. Buyers who need an internal PCIe card for a permanent build or who require a newer Wi-Fi standard should look at something else.

Questions about this item

Does the USB 3.0 connector need a USB 3.0 port on my PC?

It works in a USB 2.0 port but runs at USB 2.0 speeds; a USB 3.0 port is required for the full 10× throughput.

The dual 5 dBi antennas screw onto the adapter — how far should I turn them?

Tighten each antenna by hand until snug; over-tightening can strip the RP-SMA threads and weaken the signal.

How often should I clean or replace the 5 dBi antennas?

Wipe the antenna bases with a dry cloth if dust builds up; the antennas are passive and do not wear out, so replacement is only needed if physically damaged.
