    Can someone "decipher" the info regarding Wireless Lan Certification?
    I don't understand the following:
    Intel 5100 Certification
    Tested Dual-Band
    Spatial Selectable
    Streams Maximum
    Transmit 1
    Receive 2

    The transmit 1 means it can transmit a max of 150Mbps in 802.11n over 1 stream.
    The Receive 2 means it can receive over 2 spatial streams for 300mbps.

    Huh, always assumed the 5100 can transmit/receive on 2 streams each. That explains why it's limited to 150Mbps on the upload. No wonder the 5100 sucks over the 5300, even with current equipment.

    Dual band means 2.4 or 5Ghz.

    Oh Thanks.
    Anyway I kind of got suckered over E-Bay
    Currently they are selling lots of Wireless Card said as
    Atheros AR5BXB92 AR9280 300M wireless card 802.11B/G/N
    However they are acutally AW-NE772 WirelessCard.
    Device Manager ID it as Atheros because it is based on Atheros 9000 Chipset hence uses the same driver.
    Moreover the Wireless Certification is different from the genuine atheros card made by Atheros.
    It has
    AW-NE772 Certification
    Tested Dual-Band
    Spatial Selectable
    Streams Maximum
    Transmit 1
    Receive 1
    Compared to the real Atheros Card
    Tested Dual-Band
    Spatial Selectable
    Streams Maximum
    Transmit 2
    Receive 2
    Hope this piece of info will keep you guys updated
    If anyone wants to buy real atheros cards they should find "SparkLan Atheros N" instead
