|Transfer more data faster with 802.11ac, the Wi-Fi successor to 802.11n. This plug-in USB 3.0 wireless adapter utilizes two radio bands (2.4GHz and 5GHz) for bandwidth up to 867Mbps, significantly faster than 802.11n. By avoiding the crowded 2.4GHz band, you'll experience less collisions and packet losses due to interference. When a 802.11ac access point isn't available, the adapter falls back to 802.11g/n on the 2.4GHz band. Powerful protection supports the industry data encryption standards to protect your data and networking activity. Includes software on CD-ROM. Requires Microsoft Windows 7 or Mac OS 10.8+.
