Edimax EW-7612PIn V2

An internal network Wi-Fi card that gives you a simple way to connect your computer to a wireless network. The card features a pair of removable 3dBi high gain antennas. The PCI Express card slot for high-bandwidth data transfer will make it easy for you to use the fast IEEE 802.11n Wi-Fi standard with a transfer rate of up to 300Mbps and extended signal coverage. Of course, backward compatibility with networks and devices running on previous IEEE 802.11b/g standards is a must. Reliable data security is provided by 64/128-bit WEP encryption and/or WPA/WPA2 encryption with AES and WPS encryption standard with easy configuration.
