1. click start and run. in the open field, enter winipcfg. then press the enter key or the ok button.
2. when the ip configuration screen appears, select the ethernet adapter you have connected to the router via a cat 5 ethernet network cable. see figure c-1.
3. write down the adapter address as shown on your computer screen (see figure c-2). this is the mac address for your ethernet adapter and is shown as a series of numbers and letters.

the mac address/adapter address is what you will use for mac address cloning or mac filtering.
the example in figure c-2 shows the ethernet adapter’s ip address as 192.168.1.100. your computer may show something different.

the mac address is also called the adapter address.
