Judith MacFadyen What do I ne
ed to know?
The Eduroam Wi-Fi security certificate is being renewed at 6pm on Tuesday 9th December 2025. When you are next on campus after this, you need to apply the new certificate before you can connect to Eduroam.
What do I need to do?
The first time you are using Wi-Fi on campus after the certificate change, you will need to “forget” the Eduroam Wi-Fi network on your device and then re-join Eduroam, re-entering your username and password (particularly iOS users).
