In order to maintain security and provide a stable networking environment, CMU requires all network devices be registered to your personal Global ID. In addition, CMU requires all Windows-based computers to pass a series of security checks before they are allowed to access the campus network.

To avoid any potential delays, it is highly encouraged that you try to register your computer yourself. The network registration process is designed to be simple and accomplished in just a few easy steps:

  1. Prepare your Windows-based computer

  2. Connect to the CMU network

  3. Open your web browser (Firefox, Internet Explorer, Safari, etc.), and try navigating to a website (e.g. or

  4. Use your Global ID to register your computer and run the Client Security Agent by following the on-screen instructions

Network registration is still required for computers running other operating systems (such as Macs), and other network devices (such as game consoles), but it is not necessary to run or pass the Client Security Agent check.


2017 ResNet Depots

The 2017 Resnet Depots are available to on-campus residents needing assistance connecting to CMU's network. The Resnet Depots are conveniently located across campus at the following locations:

  • North Depot: Located at the CMU Help Desk just inside the Park Library South Entrance
  • East Depot: Located in the Woldt Hall Computer Lab Classroom, near CMU Connect Cellular Services
  • Towers Depot: Located in Kulhavi Hall Classroom 142


Preparing your Windows-based computer

Following these instructions, either from home or when you arrive on campus, will help you prepare your computer to pass the initial network registration security check:

  1. Run Windows update

    To update your Windows operating system:

    Click on the Start Menu, go to All Programs, select Windows Update.


    Open your Internet Explorer browser, click on “Tools” in the menu bar, and select “Windows Update”.

  2. Install/update anti-virus software

    If you already have an anti-virus software package installed on your computer, you'll need to make sure it has been updated with the latest anti-virus definition files.

    If you currently lack an anti-virus software package, or the software you have installed on your computer has expired, CMU recommends Microsoft Security Essentials, which is free to download and use on your personal computer. For more information, please review the installation instructions below. Remember to uninstall any other anti-virus software you may have installed before installing Microsoft Security Essentials! During the installation process, you will be prompted to update Security Essentials, ensuring you have the most up-to-date protection against viruses and other security threats.

    Please note that, if you are using a computer with Windows 10 installed, you may not need to install Microsoft Security Essentials, as Windows Defender comes pre-installed. Check the Update & Security section in your computers Settings menu to ensure Real-time Protection is turned on.

Connecting to the CMU network

There are three possible options for connecting your computer to the CMU network:

  1. Ethernet

    Generally, this provides the fastest and most reliable connection speeds, especially for initial network registration, but it does require an Ethernet cable. Ethernet cables are available for purchase at the Help Desk or local department stores.

  2. The secure (encrypted) "Cmich GOLD" wireless network

    This is a more convenient option long-term, but it does require some upfront configuration before you can initially connect. A utility is available in the Software Download Center that automatically configures this connection on Windows 7 and Windows 8 computers. Instructions for manual configuration are available for other computer operating systems as well.

  3. The unsecure (unencrypted) "cmich_open" wireless network

    This is the most convenient wireless option for a short-term connection, until you can configure your computer for a connection to Cmich GOLD. While it does not require any upfront configuration before you can initially connect, it will require you to sign in with your Global ID each time you do. Unlike Cmich GOLD, connections to cmich_open are not encrypted, though information transferred over certain websites that utilize the HTTPS protocol is still secure (generally, these pages are denoted with a "padlock" icon in your web browser).


Please note, there are a variety of factors that can impact wireless network speed, availability, and signal strength. To limit potential interference, the unauthorized use of routers, switches, modems, wireless access points, and other devices that can impact the security and stability of the network is strictly prohibited. See the Responsible Use of Computing policy.


Other Computer Operating Systems (Macs, Linux, etc.)

Macs and other computers that are not running a Windows Operating System (OS) will not be prompted to run the same security checks required for Windows OS computers. However, they will still need to be registered on the CMU network with your Global ID and password.


Other network devices (game consoles, smart TVs, etc.) 

In addition to desktop and laptop computers, you may have other devices that are capable of network access. Like computers, these devices must be formally registered on the CMU network, but they may lack the web browser necessary for you to register them on your own. These devices may include game consoles (Xbox, Playstation, etc.), smart phones, smart TVs, e-book readers (Kindle, etc.), among others. For your convenience, a self-service module is available to register these devices at  You will need your global id, password and the MAC address of your device in order to take advantage of this utility.  For more detailed information regarding this process, please click here.   For assistance registering these devices, contact the Help Desk at (989) 774-3662.
