How to Register Your Device for Internet Access

In order for you to get Internet access from anywhere on-campus or in residential housing ("ResNet"),  you will first need to register the hardware (MAC) address of either your mobile device (smartphone, laptop or tablet) or Ethernet card (wired connection in some computers). This can be done automatically using the Express Registration Tool or manually.

To register the MAC address you must have either a valid UCInetID, or for those who don't have UCInetID, you may use the Guest Registration system. Details on how to do both are below.

Note: Peer to Peer (P2P) Applications Are Not Allowed Over the Wireless Network

Two Ways to Register

1. Express Registration

From your mobile device select the network "UCInet Mobile Access" (or "Resnet Mobile Access" if you are living in undergrad housing) and then open a web browser and try to connect to any web page. You should be redirected to our Express Registration ("ExpressReg") page where you will be guided through the registration process. Refer to the directions below.

If you are not automatically redirected, please visit the website and select the "ExpressReg" option. Alternatively, you may select the "Device Registration" option to manually register your device (NOTE: You must have a UCInetID in order to complete the manual registration process).

The two most common reasons why users struggle to connect are:

  • they have a Static IP set on their device (e.g. IP address of for example)
  • they have a Static DNS address set on their device (e.g. you cannot use Google DNS addresses like or during the Express Registration process)

Please ensure that your network settings are set to DHCP and remove these settings. By doing this, your device will automatically grab an IP address and DNS address from the network. Failure to remove these static settings will prevent you from connecting.

If you are still having trouble, please feel free to contact the Help Desk at (949) 824-2222.

Visitor Access Restrictions

We offer limited access to visitors to the UCI campus. The following restrictions apply to visitors using UCInet Mobile Access:

  1. Visitor access to the UCI network is granted for a 24-hour period, and they may only register 7 times in a 30-day period.
    • From Memorial Day to Labor Day, we extend access to 7 days because of the influx of visitors during the summer who attend the CAMP & COSMOS programs. Visitors who are here longer than 7 days will need to re-register their devices weekly.
  2. Visitor access is restricted to web traffic (HTTP and HTTPS), email (IMAP and authenticated SMTP) and SSH.

If you need longer access than what is provided by Visitor Registration, a UCI faculty or staff member may register you as a guest under their UCInetID for up to 4 weeks using Manual Registration (see Manual Registration tab above). For longer stays, you may be able eligible for a Sponsored UCInetID.

UCI also participates in Eduroam for visiting academics.

Other Wireless Networks on Campus

Besides UCInet Mobile Access, there are several other networks/SSIDs you can connect to. Below are the network SSID names, along with their requirements:

  • eduroam - No MAC registration is required.

The following two SSIDs are visible on campus in the School of Health Sciences and the Gottschalk Medical Plaza. They are meant solely for HS users.

  • UCIClinic-PSK - Registered MAC required and you must know your HS username and password (mostly used for mobile devices in the clinics). Non-broadcast. The address space is
  • UCIMCNetMD - No MAC registration required, but you must know the SSID password (used for medical devices - unfortunately OIT does not have this password). Broadcast. The address space is

UCI Medical Center Wi-Fi

The UCI Medical Center (UCIMC) has instructions on how to join their wi-fi network in Orange. The SSID in Orange is called UCIHealth (the password is ucirvineaccess).

Subletting Your Apartment

If you live in grad housing and are planning to sublet your apartment, it's important to realize if your subletter is not affiliated with UCI (meaning they don't have a UCInetID), then they will not have internet access automatically.

In order for the subletter to have internet access, you will need to manually register their devices' MAC addresses under your UCInetID.

  1. Ask them to find their MAC address using these instructions.
  2. Once they provide you with the addresses you'll need to use our Mobile Access Registration tool to register all of them.

By registering their devices under your UCInetID, you accept full responsibility for anything they do while using our network.

Please do NOT submit Sponsored UCInetID requests for subletters as they will be rejected.

2. Manual Registration

Register your hardware (MAC) address from any computer already connected to the Internet.
