Hola
Mediante este código obtengo los bytes enviados y recibidos por la red.
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) _
Handles Timer1.Tick
Dim nics As System.Net.NetworkInformation.NetworkInterface()
nics = System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()
For Each nic As NetworkInterface In nics
Dim S As Integer = nic.NetworkInterfaceType
If nic.OperationalStatus = 1 Then
If S = NetworkInterfaceType.Wireless80211 Or S = NetworkInterfaceType.Ethernet Then
Dim ipv4Stats As System.Net.NetworkInformation.IPv4InterfaceStatistics
ipv4Stats = System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces.First.GetIPv4Statistics
Label1.Text = String.Format("Enviado: {0} bytes", ipv4Stats.BytesSent.ToString("##,##"))
Label2.Text = String.Format("Recibido: {0} bytes", ipv4Stats.BytesReceived.ToString("##,##"))
End If
If S = NetworkInterfaceType.Ppp Then
Dim ipv4Stats As System.Net.NetworkInformation.IPv4InterfaceStatistics
ipv4Stats = System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces(1).GetIPv4Statistics
Label1.Text = String.Format("Enviado: {0} bytes", ipv4Stats.BytesSent.ToString("##,##"))
Label2.Text = String.Format("Recibido: {0} bytes", ipv4Stats.BytesReceived.ToString("##,##"))
End If
End If
Next
End Sub
Pero no cuadra con los mostrados por Windows a través del cuadro "Estado de Conexión de red inalámbrica":
