Is it 802.11a, 802.11b, or 802.11g?

    If DDK says:

    typedef enum _NDIS_802_11_NETWORK_TYPE
    {
    Ndis802_11FH,
    Ndis802_11DS,
    Ndis802_11OFDM5,
    Ndis802_11OFDM24,
    Ndis802_11NetworkTypeMax
    } NDIS_802_11_NETWORK_TYPE, *PNDIS_802_11_NETWORK_TYPE;

    Is this true:

    802.11b = Ndis802_11FH or Ndis802_11DS
    802.11a = Ndis802_11OFDM5
    802.11g = Ndis802_11OFDM24

    Thanks

  2. From the MSDN:
    Ndis802_11FH
    Indicates the physical layer for the frequency-hopping spread-spectrum
    radio.
    Ndis802_11DS
    Indicates the physical layer for the direct-sequence spread-spectrum
    radio.
    Ndis802_11OFDM5
    Indicates the physical layer for 5-GHz OFDM radios.
    Ndis802_11OFDM24
    Indicates the physical layer for 2.4-GHz OFDM radios.
    If the device supports 802.11g, then the driver must return Ndis802_11DS and
    Ndis802_11OFDM24 in the list of supported types, in addition to any other
    types supported.

    Good luck,
