In a previous post entitled “How to get unlimited free Internet at Airports“, I showed you how to circumvent the time limit imposed by the “free” Wi-Fi connections in certain airports.

For that trick to work, you were required to update the MAC address of your computer each time the free time is over.

In this blog post, I am going to share with you the ChangeMACAddressBatch script that I wrote with the help and instructions from the excellent Batchography book.

The script makes use of various recipes illustrated in the Batchography book (in Chapter 4) and uses the various Batch scripting language syntax (Chapters 1 and 2) and methodologies (Chapter 3). Therefore, I will not be explaining the script’s contents or how it works because it will become evident if you read the Batchography book.

Get the book from Amazon:

• Paperback edition
• E-book edition

• An Ethernet adapter
• 2 x VMWare virtual adapters
• A Wi-Fi adapter

Using the keyboard, type the adapter number that you want to inspect and/or change its MAC address:

Let’s press “4” in this case and go inside that adapter’s information screen. Continue reading “Batchography: Changing the MAC address on Windows – A free Batch script”
