The D-Link DWA-160 is a compact USB Wi-Fi adapter designed to add or upgrade wireless connectivity for your desktop or notebook computer. It operates on a dual-band system, supporting both 2.4 GHz and 5 GHz frequencies, which allows you to handle general internet browsing on one band while reserving the other for more demanding tasks like streaming high-definition video. This flexibility is supported by the IEEE 802.11a, b, g, and n standards, reaching speeds of up to 300 Mbps. Inside its small white housing, the device utilizes 2x2 MIMO technology with two internal antennas providing a 4 dBi gain and a transmission power of 18 dBm. This internal design keeps the adapter streamlined, measuring just 79.5 x 23 x 10.8 mm and weighing only 11 g, so it doesn't obstruct other ports on your machine. It connects via a USB 2.0 interface and is compatible with Microsoft Windows XP SP3, Vista, 7, and 8, making it a practical choice for users with older hardware who need a reliable wireless connection.
