SSH connectivity test issue with Excel VBA

Hi all,
I need some help on a project that I have. First this is what I'm trying to do.
On an excel Sheet I have a column with IP@. Based on the different IP@, I need to initiate an ssh connection with giving login credential and then log. If the connection is ok, and login password is working I will change the color of the cell or set in a first column that the connection is ok and if login is working set in a second column ok if credential work or failed if credential is not working. I need also that the script wait for the end of the putty before doing the next IP@.

To do this I have try 2 way based on some tips that I found in different forum.
Here is the first way:

Sub Button1_Click()
    Dim wSheet As Worksheet
    Dim wsh As Object
    Set wsh = VBA.CreateObject("WScript.shell")
    'Dim waitOnReturn As Boolean: waitOnReturn = True
    Dim waitOnReturn As Boolean: waitOnReturn = Wait
    Dim WindowStyle As Integer: WindowStyle = 1
    Dim errorCode As Long
    Dim fname As Variant
    Dim FileFormatValue As Long
    Dim login As String
    Dim password As String
    Dim protect As String
    Dim IPAdd As String
    Dim rng As Range, cell As Range
    
    Set rng = Range("B2:B7")
    For Each cell In rng
        IPAdd = cell.Value
        errorCode = wsh.Run("plink " & IPAdd & " -P 22 -l admin -pw Password", WindowStyle, waitOnReturn)
        If errorCode = 0 Then
           MsgBox "Connection to Device Done!"
        Else
           MsgBox "Connection to VSM Sharepoint Failed"
        End If
    Next cell
    
End Sub

Select allOpen in new window

the second way is as follow:

Option Explicit

Public Const WM_CLOSE = &H10
Public Const INFINITE = -1&
Public Const SYNCHRONIZE = &H100000
Public Const STANDARD_RIGHTS_REQUIRED = &HF0000

SendKeys "{ENTER}", True

'Tunnel is now created
Next cell

End Function

The issue I face is with the first way, I can't use the sendkeys function due to waitonreturn but this way is waiting that treatment is finish before going to the next cell.
With the second way, I can use the sendkey with no issue but at the difference, the script do not wait that the first putty is finished before going to the next cell IP@

I hope that if it's clear enough but in case, do not hesitate to ask for more clarification
Thanks in advance for your help
