Networking & Wireless

ITS manages the campus network, including high-speed access to the Internet. We manage the infrastructure, which includes building wiring, fiber runs between buildings, and active electronics located in each building on campus. ITS supports campus routers, and works with other departments in Ann Arbor to integrate the University network. We utilize network monitoring software to help identify and resolve problems that may occur.

Here on campus, ITS provides wired connections for computers in classrooms, offices, labs, and the library. We also support the wireless network, which you can use from virtually anywhere to surf the Internet, check email, or login to University systems. Students can use the network on campus and off to access and use many resources, perform research, and take online courses through distance learning. Faculty can use CTools to share information online and teach courses.

ITS also provides the campus with network services such as DNS (Domain Name System), which translates the more recognizable Internet domain names [i.e. www.umd.mich.edu] into numeric Internet Protocol (IP) addresses. For assistance changing or obtaining additional IP addresses, please contact the ITS Help Desk.

ITS has developed network attachment standards and security standards to help ensure the security and integrity of all systems. These standards are consistent with University and industry recommended policies.

UM-Dearborn's wireless network offers most of the computing services that the wired network does, without the restraints of a network cable and jack. With wireless, you can access University systems, check email, surf the Internet, and perform class work. The wireless network is installed in every building on campus, including the Fairlane Center, and allows roaming between coverage areas. (Remember that signal strength and throughput decrease as you move farther from access points.)

It is important to remember that the wireless network is a shared resource. It is intended to supplement the campus wired infrastructure, not replace it. The wireless network operates at slower speeds than the wired system – and the more it is used, the slower it will be. We recommend that faculty and staff establish a standard wired connection for office desktop workstations, which will provide higher performance and better security. You are discouraged from running any high bandwidth service on the wireless network, which could slow performance for everyone. You should be considerate of others and refrain from engaging in data-intensive operations, like uploading large files or streaming video.

You will need a computer with an 802.11a, 802.11g, or 802.11n wireless network adapter.  Most laptops released within the last four years contain  an 802.11g or "n" adapter.  A web browser is required for logging in to the wireless network.  The following browsers are known to be supported for this:

• Mozilla Firefox (recommended)
• Opera
• Safari
• Internet Explorer

For security purposes, UM-D's wireless network is only available to members of the UM-Dearborn community. To access it:

1. Your computer must be configured to obtain an IP address automatically (DHCP).
2. Using your network management software, select "UMD-Wireless".
3. Start a web browser, and your home page will be redirected to the UM-Dearborn Wireless Network Authentication page.
4. Login by typing your uniqname and Dearborn password in the login boxes.
5. Your network browser will return to your predetermined home page.
6. You are now connected to the wireless network and can use your network applications.
   
   NOTE : If you roam out of range, or if your computer is in sleep mode or turned off for a period of time, you may be logged out of the wireless network.

Security is a major issue with wireless networks. Take precautions and use care in handling data. Since signals are passed through the air, wireless transmissions can be intercepted and information can be viewed in clear text (including passwords). The built-in wireless LAN security is also known to be flawed, and should not be relied upon to protect privacy. Anyone concerned about the privacy of information being transmitted by wireless should take steps to encrypt it (using Security Sockets Layer or SSL, SSH, etc.). Departments needing enhanced security can utilize Virtual Private Network (VPN) technology. ITS provides assistance and instructions on VPN for Windows and MacOSX.

Security Recommendations:

• Make sure your system Firewall is on.
• Install anti-virus software. University of Michigan offers free McAfee VirusScan software. Be sure to update it regularly and run frequent scans on your laptop.

Anyone accessing the UM-Dearborn wireless network is expected to comply with all applicable University policies governing the proper use of shared computer resources.
