Determine current LAN network interface

[Docfxit]

I have a script that lists all network interfaces to a file.

Opt("WinWaitDelay", 100)
Opt("WinTitleMatchMode", 4)
Opt("WinDetectHiddenText", 1)
Opt("MouseCoordMode", 0)
Opt("TrayIconDebug", 1) ;0-off
; Set so that tray displays current line number
Global $CMD
FileDelete(@ScriptDir & "\StaticIPAddressInterfaces.txt")
FileWrite(@ScriptDir & "\StaticIPAddressInterfaces.txt" ,(_DosRun('netsh interface ipv4 show interfaces') & @CRLF))

On my computer the StaticIPAddressInterfaces.txt file looks like this:

Idx     Met         MTU          State                Name
---  ----------  ----------  ------------  ---------------------------
  7          45        1500  connected     Wi-Fi
  1          75  4294967295  connected     Loopback Pseudo-Interface 1
 27          65        1500  disconnected  Bluetooth Network Connection
 16          25        1500  connected     Ethernet
  9          25        1500  disconnected  Local Area Connection* 16
 17          25        1500  disconnected  Local Area Connection* 17
 11          25        1500  connected     VirtualBox Host-Only Network #3
 15          25        1500  disconnected  PdaNet Broadband Connection

I would like some help in reading the file and selecting the LAN interface.

From what I have seen the possibilities are:

Ethernet

Ethernet 2

Local Area Connection

Local Area Connection (with some number)

Thanks,

You have been a member of this forum for 15 years and you need help reading a file and parsing out some information from it?  What have you tried so far?

Exactly what type of help are you looking for, can you be a little more specific?  What do you mean by "current LAN interface"?  By what criteria is one supposed to determine which interface is the "current LAN interface"?  Why wouldn't "Wi-Fi" be considered a LAN interface?  As you can, your request is lacking some significant details.

BTW: With WMI you can query the interfaces using SQL (kind of) like a database.
In the example scripts forum you'll find Scriptomatic. It generates AutoIt scripts for you to query the needed information.
