    Dim WiFi_IP As String = ""
    Dim Network_IP As String = ""
    Dim WiFi_Only As Boolean = True ' should be boolean if you want to check for a boolean

    If WiFi_Only And WiFi_IP = "127.0.0.1" Then
        ToastMessageShow("No WiFi connection", True)
    End If
 
    If WiFi_IP = "127.0.0.1" And Network_IP = "127.0.0.1" And Not(WiFi_Only) Then
        ToastMessageShow("No Internet connection", True)
    End If
