Вам нужно запросить WMI, чтобы получить эту информацию. Самый простой способ сделать это из Python - просто выполнить этот скрипт VB (он работал для меня):
Option Explicit
On Error Resume Next
dim strComputer
dim wmiNS
dim wmiQuery
dim objWMIService
Dim objLocator
dim colItems
dim objItem
Dim strUsr, strPWD, strLocl, strAuth, iFLag 'connect server parameters
Dim colNamedArguments 'WshNamed object
subCheckCscript 'check to see if running in cscript
Set colNamedArguments = WScript.Arguments.Named
strComputer = colNamedArguments("c")
subCheckArguments
wmiNS = "\root\cimv2"
wmiQuery = "Select BytesTotalPerSec from Win32_PerfFormattedData_Tcpip_NetworkInterface"
strUsr = colNamedArguments("u") '""'Blank for current security. Domain\Username
strPWD = colNamedArguments("p") '""'Blank for current security.
strLocl = "" '"MS_409" 'US English. Can leave blank for current language
strAuth = ""'if specify domain in strUsr this must be blank
iFlag = "0" 'only two values allowed here: 0 (wait for connection) 128 (wait max two min)
Set objLocator = CreateObject("WbemScripting.SWbemLocator")
Set objWMIService = objLocator.ConnectServer(strComputer, _
wmiNS, strUsr, strPWD, strLocl, strAuth, iFLag)
Set colItems = objWMIService.ExecQuery(wmiQuery)
For Each objItem in colItems
Wscript.Echo funLine("Name: " & objItem.name)
Wscript.Echo "CurrentBandwidth: " & funConvert("M",objItem.BytesTotalPerSec )
Next

Sub subCheckCscript
If UCase(Right(Wscript.FullName, 11)) = "WSCRIPT.EXE" Then
Wscript.Echo "This script must be run under CScript"
WScript.Quit

end Sub
