If you happen to have an internet service provider that records and provides the service based on your computer’s MAC address – well, actually, the MAC address of your network card – and you don’t know where to look for this info, then this article will be helpful to you.

In some cases, if you have to change your NIC [ network interface card, more commonly known as network card or LAN card ], or you change your computer, buy a new one instead of the old one, chances are, you’ll discover when you plug in your cable into the network socket of your new computer, that you cannot be connected to the internet as you used to.

Some internet service providers [ ISP ] , like some of those in my area , have a phone number that you have to call, and they require customers to record the new computer’s or new network card’s MAC address or “phisical address” as they are also known.

Locating the MAC or phisical address of your network card

Write down the phisical address of your network card, and have that ready when you call your ISP to register the new PC or new network card with them.

After they confirm that they’ve registered the new MAC address in their system, reboot your computer and in a few minutes after that, your PC will be connected to the internet again.

This info is also useful for allowing your computer to be awaken over the internet with the help of the WOL [ wake-on-lan ] facility, if your computer and your network card do posess that capability and it’s turned on in the BIOS or motherboard settings.

Hope this helped !
