In order to connect personal laptops to the wired network, you must provide the MAC Address (Hardware Address) of the computer to the IT Administrator.

The IT Administrator will assign to your computer an IP address that you can use when you are connected to the local network by a network cable. The IP Address is assigned by using the DHCP protocol, so you have to configure the network card of your laptop this way.

If you don't know how to find the MAC Address follow these guidelines:

1. Open the System Preferences panel
2. Click on Network
3. Select the Built-in Ethernet from the Show drop-down menu
4. Click the Ethernet button
5. You will find a line of this type

  Ethernet ID: 00:17:F2:26:6D:78

1. Your MAC Address is this one

1. Click on the Start button
2. Select Run…
3. execute this command

  cmd

1. click inside the black window that appears and execute this command

  ipconfig /all

<note tip> Depending on how many network cards your computer have the output can be a little long, use the side bar to scroll. </note>

1. Find the section regarding the network card you want to use
2. Write down the Physical address (something similar to 00:17:F2:26:6D:78)

1. Open a terminal window
2. Execute the command

  /sbin/ip link

1. Write down he MAC Address (something similar to 00:17:F2:26:6D:78)

<note tip> If you can't execute the /sbin/ip link command try with the command ifconfig. </note>
