Unable to connect after 5/21/2025 / Wireless Network

Problem

• I am unable to rejoin Miami's wireless network or eduroam after 5/21/2025

Cause

• IT Services recently updated the SSL certificate used to encrypt the traffic on the wireless networks — your device is still trying to use the old certificate

Resolution 

1. Forget the wireless network
   • Remove or forget a wireless network on a macOS computer 
     • Note: You may need to uninstall the MU-Wireless and or MiamiOH-Secure profile if you have it installed. In your Apple menu, go to System Preferences and select Profiles. Remove anything that references MU-Wireless or MiamiOH-Secure by selecting it and clicking the minus button
   • Remove or forget a wireless network on a Windows computer
   • Remove or forget a wireless network on an iOS device
   • Android: Varies by flavor and device type. Go into your Settings, and then Network or Connections
2. Re-join the network
   • MacOS 
     1. Select the Wi-Fi symbol at the top-right side of the screen and select the network
     2. Follow the prompts to connect:
        • Connect a Windows computer to MiamiOH-Secure
        • Connect an iOS device to MiamiOH-Secure
        • Connect an Android device to MiamiOH-Secure

Notes

• These steps can be used to rejoin eduroam, because it is configured the same way
  • Also see Wireless Network / eduroam configuration for wireless connection
• You may be prompted that the certificate used is not trusted: This is due to some devices not trusting all certificate chains
