AC1300 dual-band Wi-Fi adapter

This USB 3.0 wireless adapter delivers up to 1300 Mbps combined throughput across 5 GHz and 2.4 GHz bands. It targets desktop and laptop users who need faster, more stable connections for gaming, streaming or large downloads without installing an internal card. Compatibility spans Windows 10, 11 and Mac OS 10.9 through 10.15.

Dual 2 dBi antennas with 180° rotation

Two adjustable antennas improve signal reception and let you angle them 40 to 60 degrees for optimal coverage. The USB 3.0 interface runs at ten times the speed of USB 2.0 while remaining backward compatible, so the adapter works on older ports without losing the physical connection. Its compact form factor makes it easy to carry between machines.

Replaces built-in Wi-Fi or USB 2.0 dongles

The upgrade is worthwhile when an internal wireless module is missing, faulty or limited to slower speeds, and when a USB 2.0 adapter cannot sustain 867 Mbps on the 5 GHz band. It does not suit users who require Bluetooth connectivity or an internal PCIe installation.

Questions about this item

What maximum link rate does the USB 3.0 interface support on the 5 GHz band?

The USB 3.0 port allows the 5 GHz band to reach 867 Mbps, ten times the throughput of USB 2.0, while remaining backward compatible with USB 2.0 sockets.

How much clearance do the dual 2 dBi antennas need when rotated?

Each antenna pivots 180°; tilting them 40–60° is recommended, so allow enough space above the dongle for that angle.

Which operating systems does the driver support, and what common step is missed during setup?

Windows 7, 8, 10, 11 and Mac OS 10.9–10.15 are supported; the step often missed is installing the driver before plugging the adapter into the USB port.
