MichiganTech Wireless Changes – Certificate Warning

Michigan Tech is implementing a new controller for the MichiganTech wireless network.  This change is needed to implement AirPrint and GooglePrint features this fall.  This change will only affect the MichiganTech SSID.

After Wednesday August 19 at 7 AM you may see a certificate popup on your mobile device or laptop (similar to the image below).  When you see this message, click Accept and you will continue to be connected to the wireless network.

As always, if you have any issues or questions, please contact IT Help at 906-487-1111 or


New Wireless Certificate

IT Security has replaced the expiring security certificate associated with the MichiganTech SSID present on our wireless network. This change will cause Apple devices to prompt the user to accept the new certificate. It is safe to accept this new certificate. The screenshot accompanying this article shows an example of what an iPhone displays when this happens. This link here shows what you would see on an Apple computer.

Security certificates are made to expire by design. As computer technology evolves, older generations of encryption technology (on which certificates are based) become vulnerable to more powerful computers. By expiring certificates, the risk associated with older technology is mitigated.

This new certificate will not expire until 2016.
