Edimax EW-7811Un

The Edimax EW-7811Un is a mini USB wireless adapter that supports high speed connection rates. Despite its small size, it supports speeds up to 150 Mb/s. The adapter achieves these speeds using the modern 802.11n standard, which is up to 3 times faster than the usual 11g connection. Simply plug it into your computer's USB port and enjoy an incredibly fast wireless network access. The Edimax EW-7811Un supports intelligent transmission power supply. In this way it optimizes the transmission power to only consume the essential part of the electrical power needed for a trouble-free data transmission. This saves between 20-50 percent of electricity compared to conventional adapters.
The Edimax EW-7811Un supports WPS, a tool for easy and fast setup of a wireless network. If your access point also supports this feature, you can set up a secure connection by pressing two buttons. The Edimax EW-7811Un is probably one of the smallest adapters on the market. You'll appreciate it especially on laptops where you will never have to unplug it after installation.
