TomC. I followed that link and found an app that helps you to locate, change MAC addresses and other things.
Its a free app and it is very interesting to use.
http://www.technitium.com/tmac/index.html Scroll down to the bottom to download it.
I was planning to upload in image here showing my various MAC addresses compared to what SM reports but the upload refused to finish.
I guess I have to tell you instead.
When i run MAC in SM it reports 5 different MAC Addresses separated by a comma.
2C-8A-20-52-41-53,20-41-53-59-4E-FF,00-17-F2-0F-DE-C4,00-17-F2-0F-DE-C5,00-16-CB-25-91-23
The first 2 Im not sure were they come from but I have something called "Virtual CloneDrive" that is running.
Maybe 1 of them comes from that app. Maybe both. But that doesnt sound very likely. Does it?
The 3rd one is my first "Local Area Connection". It is not active.
4th is my active "Local Area Connection 2"
The last one is my Bluetooth Network Connection. Its not active.
So. Me and Sunsynth noticed that after every restart the 4 first numbers in this series changed.
Maybe that is because they arrive from that Virtual Clone Drive app or a similar app.
Maybe we should only use the last reported MAC? The one after the last comma?
Would be nice to see others test this to see if the real network ports are always last or if this is completely random.
