etc...). So could anyone plz let me know, If there is some WMI class
for that which i can use.

Hey Anant.

You can find some information in Win32_NetworkAdapter class.
Look at the following properties: Name, Manufacturer, ServiceName.

It doesn't work. Because lots of wifi adapter register itself as a
eathernet Adapter and they show their AdapterId 0 rather then 9.

Is their some other property, which will be unique to WIFI adapter. Or
some other class, which i can query for WIFI adapters.

Maybe you could look at the associators of that class to get the network
configuration for each adapter (and check which protocols it's
configured to use)??? 802.11b, for example, would be WIFI. I'm not sure
if this will work or not but it's worth a try.

To distinguish between differnet types of network cards you can query
the MSNdis_PhysicalMediumType class.
It will return the following classification (taken from ntddndis.h):
typedef enum _NDIS_PHYSICAL_MEDIUM
{
NdisPhysicalMediumUnspecified,
NdisPhysicalMediumWirelessLan,
NdisPhysicalMediumCableModem,
NdisPhysicalMediumPhoneLine,
NdisPhysicalMediumPowerLine,
NdisPhysicalMediumDSL, // includes ADSL and UADSL (G.Lite)
NdisPhysicalMediumFibreChannel,
NdisPhysicalMedium1394,
NdisPhysicalMediumWirelessWan,
NdisPhysicalMediumNative802_11,
NdisPhysicalMediumBluetooth,
NdisPhysicalMediumMax // Not a real physical type, defined as
an upper-bound
} NDIS_PHYSICAL_MEDIUM, *PNDIS_PHYSICAL_MEDIUM;

Please notice that regular LAN cards do not appear in the list.
So I guess the right way to use it is to find all the 802.3 cards from
Win32_NetworkAdapter and then find their real type using this class. If
they don't have a class here, then they are regular 802.3 adapters.

BTW, more interesting information for WiFi cards can be found in
MSNdis_LinkSpeed, MSNdis_80211_ReceivedSignalStrength and
Win32_NetworkAdapterConfiguration (which is also for regular adapters).
You should investigate all the MSNdis_80211_* classes for more
information.

Hope this helps,
Joe.
