The Win32_NetworkAdapter class is deprecated. Use the MSFT_NetAdapter class instead. The Win32_NetworkAdapter WMI class represents a network adapter of a computer running a Windows operating system.
Win32_NetworkAdapter only supplies IPv4 data. For more information, see IPv6 and IPv4 Support in WMI.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

The statement above is wrong and misleading, at least on Win7.
The code below works on Win7 64 bit.
{code}
hr = pclsObj->Get(L"Speed", 0, &vtProp, 0, 0);
if (SUCCEEDED(hr) && (V_VT(&vtProp) == VT_BSTR)) {

Method For Finding the Default Network Adapter.
I use this query first and then run a query based on the result.
"SELECT InterfaceIndex, Destination FROM Win32_IP4RouteTable WHERE Destination='0.0.0.0'"
You should only have one default network destination 0.0.0.0.
The InterfaceIndex is then used to grab the Network Adapter you want.
"SELECT * FROM Win32_NetworkAdapter WHERE InterfaceIndex=" + insertVariableHere

More Than You Think!
Warning: There are a lot of these adapters on a typical computer system. You have to do considerable processing in order to figure out which is the real one that you want!
Here are some guidelines to qualify Win32_NetworkAdapter:
AdapterType: "Ethernet 802.3"
MACAddress: String Length > 16
Availability: 3
PNPDeviceID: InStr ( PNPDeviceID, "PCI") = 1
Installed: vbTrue
ConfigManagerErrorCode: 0
:
You will still get more than one valid network adapter...
Then you need to search through the collection of Win32_NetworkAdapterConfiguration, qualify like this:
Index:
MACAddress: Length > 16
DefaultIPGateway: String Length > 6
DNSServerSearchOrder: Array of strings with length > 6
IPEnabled: vbTrue
IPAddress: Array of strings with length > 6
...by then you should have it narrowed down to one or two configured adapters!
