ping silenciosamente em segundo plano - excel, vba

Quando executo o código a seguir, uma janela de comando preta é aberta e pisca até a hora em que todos os dispositivos são exibidos. Como posso executá-lo silenciosamente?

Sub PING()

Application.ScreenUpdating = False
Dim strTarget, strPingResult, strInput, wshShell, wshExec

With Sheets(1)
shlastrow = .Cells(Rows.Count, "B").End(x1up).Row
Set shrange = .Range("B3:B7" & shlastrow)
End With

For Each shCell In shrange
strInput = shCell.Text

If strInput <> "" Then
strTarget = strInput
setwshshell = CreateObject("wscript.shell")

Set wshExec = wshShell.exec("ping -n 2 -w 5 " & strTarget)
strPingResult = LCase(wshExec.stdout.readall)

If InStr(strPingResult, "reply from") Then
shCell.Offset(0, 1).Value = "Reachable"
shCell.Offset(0, 2).Value = "Time"
Else
shCell.Offset(0, 1).Value = "UnReachable"
shCell.Offset(0, 2).Value = "Reachable"
End If
End If

Next shCell

End Sub

Aqui está o código para isso
