    Speed should be 150Mbps but it is because it overpasses the 802.11g speed. But the reality is that its maximum will be 65Mbps :S

    Just for people to know a little bit more about their machines.

    Also the chip shares Bluetooth bandwidth, so if you do not use Bluetooth devices, turn it off in order to gain a little bit more of bus and bandwidth for the chip. 

    Here are the technical aspects:

     

    roduct Description
    Product Features

    • Operate at ISM frequency bands (2.4GHz)
    • SDIO for WiFi and UART for Bluetooth
    • IEEE standards support: IEEE 802.11b, IEEE 802.11g, IEEE 802.11n, IEEE 802.11d, IEEE 802.11e, IEEE 802.11h, IEEE 802.11i
    • Fully Qualified for Bluetooth 2.1+EDR specification including both 2Mbps and 3Mbps modulation mode
    • Fully qualified for Bluetooth 3.0
    • Fully qualified for Bluetooth 4.0 Dual mode
    • Full–speed Bluetooth operation with Piconet and Scatternet support
    • Enterprise level security which can apply WPA/WPA2 certification for WiFi.
    • WiFi 1 transmitter and 1 receiver allow data rates supporting up to 150 Mbps downstream and 150 Mbps upstream PHY rates
