How to get the Network Address (MAC address) of a Network Adapter

What is a Network Address?

Every Network Adapter has a unique Network Address. We sometimes need you to provide the Network Address to facilitate connection to the Trinity data networks. For example, if you want to connect a new computer to the staff wired network, we will need the Network Address of the Wired Network Adapter. If you are connecting a laptop, we will also need the Network Address of the Wireless Adapter.

Network address always consists of 12 characters. It is usually presented in hexadecimal format. This means that it may contain numbers 0-9 and letters A-F. It is often presented with hyphens, you can omit them.

On a standard PC from an official Trinity supplier, the Network Address is usually located on a label attached somewhere on the machine. If you cannot find it, or you have a non-standard device, you can obtain the network address using instructions below.

Some laptops, when running off the battery, will turn off network cards that are not in use in order to save power. If this is the case, you will need to either connect to ac power or disable this power saving feature in order to get the adapter address.
