Intel 2777324 Dual Band Wireless Network Adapter (Bluetooth, 867Mbps, WiFi) (Personal Computers)
I have installed the card in my 4 year old laptop, with whom I previously, under optimum conditions, with speeds of max. 10 MB / sec (80Mbit / sec) could copy, which represented the maximum of wireless chips (Atheros AR5B95, 802.11n, 150 Mbit / sec).
