Mac Wireless Issues: Resolution

SMU Wireless LogoOn January 13, the security certificate for PerunaNet was renewed.  Typically, computers will prompt to accept the new certificate and reconnect without issue. However, multiple Macs and iOS devices were failing to present the “accept certificate” window, and were therefore not updating the wireless certificate.  The following solutions have been identified and should be performed on any device that is having difficulty connecting to PerunaNet.

Faculty and Staff SMU-managed computers (macOS)

A task was sent to all SMU Mac devices to replace the certificate.  If your device was connected to SMU_Guest after 1:30 PM on 1/17, it should receive the new cert.  Please do the following:

  1. Forget all SMU wireless networks on your device
    • Click the Apple icon > System Preferences > Network
    • Forget This Network…Click the “” button next to each SMU network (or the small circle on Ventura)
    • Click + and add a new PerunaNet profile
  2. Reconnect to PerunaNet
  3. When prompted to accept the certificate, click Accept

Student or employee personal devices (macOS)

In order to connect, you will need to delete a single file that is associated with the old certificate.

  1. Locate the main system Library folder (Finder-Go-Computer-Macintosh HD-Library)
  2. Go to Preferences > SystemConfiguration
  3. Locate and delete this file:

Please forget SMU Guest or Eduroam once connected to PerunaNet if you added those networks previously.

Mobile iOS devices

  1. Download SMU_Wireless_iOS file
  2. If prompted to choose a device, select iPhone
  3. A “Profile Downloaded” confirmation will appear, directing you to the Settings app
  4. Launch Settings
  5. Select “Profile Downloaded” from the list of settings
  6. Click “Install” in the top right corner
  7. Enter your device Passcode when prompted
  8. Click “Install” in the top right corner
  9. Click “Install” at the bottom to confirm installation
  10. Enter your SMU ID number for username
  11. Enter your SMU account password for password
  12. “Profile Installed” prompt will appear
  13. Click “Done” in the top right
