802.11n/g/b USB Wireless Wi-Fi Adapter - Realtek 5370 Chipset Wireless standards: IEEE 802.11n (Draft 2.0), IEEE 802.11g, IEEE 802.11b standards Interface: USB 2.0/1.1, Chipset: Realtek 5370, External Antenna gives better range than most micro USB adapters Frequency range: 2.4GHz ISM,RF frequency: 2412-2462Mhz (North America) Security: 64/128-bit WEP Encryption WPA, WPA-PSK, WPA2-PSK, TKIP/AES Operating Systems: Supports Windows 7 and Windows 8, Mac OS X, Linux (Debian, including Raspberry Pi and Banana Pi). While the newer single board computers have onboard Wi-Fi, the onboard chipsets aren't universally as supported if you are going to be experimenting with multiple operating systems. The RT5370 chipset provides Wi-Fi support on virtually every operating system without having to struggle with drivers. The latest drivers need to be downloaded from mediatek. The download URL is on the packaging. The published speed by the manufacturer is 150Mbps (downlink) and 72Mbps (uplink). You might be able to achieve these speeds at a distance of maybe 2 feet from the router. More realistic speeds in practical applications is more like 54-36Mbps. This adapter is a good choice for adding network connectivity for day to day to web surfing. You'll likely find high bandwidth applications like video frustrating and you'd be better off with a dedicated wireless card. This model was tested with 64-bit/32-bit Windows 7 on Dell Hardware and a Netgear Wireless Router. Likewise, support with Ubuntu, Raspbian, and Lubuntu ARM was confirmed with a Netgear Wireless Router. Buy with confidence that you can return if your specific hardware, and operating system combination doesn't perform adequately.
