Hi

If it is network connection/disconnection you want to detect, you can use
MSNdis_StatusMediaConnect, here is a VBScript example that works for me:

Set colMonitoredEvents = GetObject("winmgmts:root\wmi")._
     ExecNotificationQuery("Select * from MSNdis_StatusMediaConnect")
Do
     Set strLatestEvent = colMonitoredEvents.NextEvent
     WScript.Echo "Connected! Do something here"
     ' enable the line below if you want to exit after the first event.
     'Exit Do
Loop

If you want to check a specific adapter, use e.g. a select on the
InstanceName of the adapter:

Set colMonitoredEvents = GetObject("winmgmts:root\wmi")._
     ExecNotificationQuery("Select * from MSNdis_StatusMediaConnect" _
        & " WHERE InstanceName = '3Com 10/100 Mini PCI Ethernet Adapter'")
Do
     Set strLatestEvent = colMonitoredEvents.NextEvent
     WScript.Echo "Connected! Do something here"
     ' enable the line below if you want to exit after the first event.
     'Exit Do
Loop
