Try This :

Function HasConnectivity() As Boolean
    Dim hostInfo As System.Net.IPHostEntry
    Try 'to look for the logon server
        Dim sServer As String = Environment.GetEnvironmentVariable("logonserver")
        hostInfo = System.Net.Dns.GetHostByName(sServer.Remove(0, 2))
        Return True
    Catch 'theres no network connection
        Return False
    End Try
End Function

For Checking :

If HasConnectivity() = True Then
   ' Your Ping Code
Else
   MsgBox("not connected")
End If
