What is a MAC Address?

Each network interface card has a unique identification code known as a MAC (Media Access Control) Address. This code consists of six groups of hexadecimal numbers, representing a physical location. The address is divided into two parts: the first three sets of numbers are the Manufacturer ID, identifying the manufacturer, while the last three sets represent the Card ID, which is the network card's unique identifier. Through these two parts, we can physically distinguish each network card. Theoretically, no two cards in the world should have the same MAC Address."   

What is wireless network MAC authentication?

Wireless network MAC authentication is another authentication method that makes accessing the campus wireless network easier compared to account and password authentication. As long as you are using a registered laptop or handheld device, the base station will store the record and use it the next time you connect to the wireless network. You will not need to enter your account and password again when accessing the Internet.

Why use MAC authentication?

Devices that have not passed MAC authentication must enter their e-mail account and password every time they use the campus wireless network. This is actually quite inconvenient for people who frequently use wireless networks. Imagine that there are eight classes a day. If every class ends, you want to use the campus wireless network to access the Internet, you will have to enter your e-mail account and password eight times. In addition, mobile Internet devices are getting lighter and lighter, so it is really inconvenient to enter your account and password all the time.

Therefore, Computer and Information Network Center has enabled the "NCHU" wireless base station to provide user MAC authentication registration function starting from May 1. Users can register the MAC address of their usual mobile Internet devices (such as mobile phones) in the system and pass the authentication. There is no need to re-enter your e-mail account and password every time your mobile device uses the campus wireless network.

There is currently no limit on the type or number of devices that can be authenticated by a set of e-mail accounts and passwords.
