ASU Wired NAC - Common FAQs

What changes have been made to the ASU Wired Network?

If wired network authentication is enabled on your device, when you connect to the ASU wired network for the first time after the upgrade, you will be prompted to login using your ASURITE ID and password.
If you do not authenticate, you will receive Internet only services.
If you receive a certificate warning, accept the certificate and then proceed to login. After you successfully login the first time, your device will be authenticated and your profile will be saved.  You should only have to re-login when your password is changed. 

When do these Changes Take Effect and how will I be notified?

The Wired NAC rollout will begin in August, 2018. Once your building has been upgraded you will need to authenticate on the ASU Wired network. 

You will be notified via email prior to your building being upgraded. There will also be flyers and other forms of communication regarding the upgrade to your building.

Note that if you attempt to connect to the ASU network using a wired connection in any buildings that have been upgraded you will need to perform the authentication process to connect to the ASU network.

I am having problems connecting and authenticating to the ASU Wired network, what should I do?

If you need help, please view our knowledgebase articles. Search the knowledge base using the term "wired nac".

NOTE: If you had previously setup your device to connect to the ASU Wireless network, then you can still use Wi-Fi to connect to the ASU network. On your device, the ASU wired and wireless connections are separate and do not affect each other. 

If you need assistance then please contact the ASU Help Center at 1-855-278-5080 (toll free) or 1-480-965-6500 (local).

My computer is already authenticated and connected to the ASU Wireless. How does this affect my connection to the ASU Wireless network?

The wireless and wired connections on your device are separate and do not affect each other. If you are already connected to the ASU wireless network then that connection will not be affected by connecting to or attempting to connect the ASU wired network.

Making changes to your ASU Wired network connection will not affect any of the wireless connections you have setup on your device.

What is the ASU Network Segmentation Implementation?

ASU is making use of Cisco ISE technology to manage the different segments on the network. For example, students would typically be on a different network segment than faculty and staff. Segmentation allows optimizing the needs of the users on each specific network segment.

What is a Media Access Control (MAC) Address and why is it important?

The MAC address of your device is its unique network hardware "identifier". It is important to understand that for each network communication interface your device has it will have a separate and different MAC Address for each.

For example, if your device has both ethernet and wireless capability (as with a typical laptop) then the MAC address for the wireless connection will be different from the ethernet connection. This is because wireless and ethernet connectivity require separate hardware in the device. So each will have its own unique MAC Address or hardware identifier. Because your device does not use both the wireless and ethernet connections at the same time the device will have a separate MAC Address for wireless and for ethernet.

  • All wireless connections on your device will use the same MAC Address.
  • All wired network connections on your device will use the same MAC Address.

See this KB Article (How Do I Find My Computer's MAC Address?) for instructions on how to find the MAC Address of your device.  

Why are routers, wireless access points, video streaming devices, and wireless printers listed as ‘Prohibited’ Items?

  • Use of Routers, wireless access points, video streaming devices and wireless printers are prohibited on the ASU network.
  • Signals from personal routers and wireless printers cause interference with ASU Wi-Fi, reducing signal strength and speed for any other wireless devices in the same building or area.
  • Devices like Roku, Chromecast, wireless printers and other devices that communicate via Wi-Fi will not work on ASU Wi-Fi (ex: your laptop sending a print job to a wireless printer).
    You may have a printer; however, you must keep the wireless printing function disabled.
  • Visit and view the "Network Usage" section for more information about policies and prohibited items.

I have devices (typically gaming consoles) without web browsers and which cannot use the normal authentication method. What do I do?

In ASU managed Student Residence rooms, ASU has modified the wired network so that students can enjoy Residential Apartment style network connections. Devices plugged into wired ports in student residence rooms will not have to authenticate, and will receive static NAT IP addresses required by many Gaming Consoles to allow multi-player functionality. This functionality will not be available outside of Student Residence rooms.

Non-ASU managed Student Housing such as American Campus Communities (ACC) provide their own networks separate and different than ASU.

NOTE: If you need assistance then please contact the ASU Help Center at 1-855-278-5080 (toll free) or 1-480-965-6500 (local).
