AC1300 USB Wi-Fi adapter for desktops and laptops

The premiumwire USB wireless adapter adds dual-band 802.11ac connectivity to a PC or Mac through a USB 3.0 port. It delivers up to 400 Mbps on the 2.4 GHz band and up to 867 Mbps on the 5 GHz band. Two 5 dBi high-gain rotating antennas and built-in cooling vents help maintain a stable link through walls and during extended use.

Suitable for users upgrading older systems to AC

This adapter suits Windows 7 through 11 and macOS 10.9 to 10.15 machines that lack modern wireless hardware. Plug-and-play operation on Windows 10 and 11 simplifies setup, while other supported platforms use the supplied driver disc. Buyers who need 802.11ax or Bluetooth capability should look elsewhere.

USB 3.0 interface enables the rated AC1300

The USB 3.0 connection provides the bandwidth required for the adapter's maximum 867 Mbps 5 GHz link speed. A USB 2.0 port cannot sustain that rate, so the host port type directly determines the real-world performance ceiling.

Questions about this item

Should I expect the 867 Mbps 5 GHz rate or the 400 Mbps 2.4 GHz rate in daily use?

The adapter reaches 867 Mbps on 5 GHz and 400 Mbps on 2.4 GHz under ideal conditions; real-world throughput will be lower due to distance, walls and network congestion.

What practical throughput does the AC1300 label represent once the adapter is plugged in?

AC1300 combines the 5 GHz 867 Mbps and 2.4 GHz 400 Mbps peaks; a single connection uses one band at a time, so maximum real-world speed is the band you are connected to.

Does the USB 3.0 interface limit the 867 Mbps 5 GHz link in any way?

USB 3.0 provides up to 5 Gbps bandwidth, well above the 867 Mbps wireless ceiling, so the port does not bottleneck the adapter.
