A certificate upgrade for servers that are used to secure communications on three University of Michigan WiFi networks will require users to accept the new certificate as of May 18.
Information and Technology Services will be upgrading the certificate that authentication servers use to secure communications for devices connected to MWireless, MWireless-UMHS and eduroam.
Certificates help create a secure WiFi environment, and must be renewed every one to three years. The current certificate used by MWireless, MWireless-UMHS and eduroam is expiring and a replacement certificate will be installed on May 18.
As of that date, the first time users connect to these networks, a pop-up box will appear asking them to accept a new security certificate. It will specifically reference radius.umnet.umich.edu, and users will need to accept the new certificate to continue using the networks.
Apple iOS devices will not provide the pop-up prompt, but will continue to attempt to connect to the network unsuccessfully. To reconfigure Apple iOS devices for MWireless and eduroam, use MGuest or a cellular data connection to access and run the automated setup tool.
U-M Health System faculty, staff and students having trouble connecting to MWireless-UMHS, MWireless, or eduroam can request assistance from the UMHS Service Desk at 734-936-8000.
