instructor station) to the Ethernet jack on your laptop.*

*Please note: You will need to register and setup your computer for DHCP Service (Dynamic Host Configuration Protocol) prior to using the Ethernet connection.

Wired network tips

Understanding DHCP
  • Once registered and set up, DHCP allows you to automatically
    connect to the network on any campus classroom Ethernet jack.
  • DHCP registration should be done in advance of the time you
    need to use the network, as the registration confirmation
    process may take several minutes.

DHCP registration can be done online at:

Simply open a web browser (e.g., Internet Explorer, Firefox, Safari). You will be prompted to log in with your U of M Internet ID (X.500) and password.


Wireless network tips

If the connection is slow or does not work properly:Verify that you are connected to the “UofM Wireless” connection.

There may be other wireless network connections within range of the classroom. Connecting to a non-U of M network may cause the connection to be slow or not work properly.

If you do not have a U of M Internet ID:
Guests to campus may use the "UofM Guest" network for free.

For more information about obtaining guest access to the U of M network, please visit the following website:

Data network service and support is provided by the Office of Information Technology. For further assistance with the wireless or wired network connection, please call the 1-HELP Technology Helpline at 612-301-4357.
