eduroam, UW–Madison’s secure wireless network, will update its server certificate on Tuesday, March 31. If you receive a notification prompting you to “trust” the new certificate for eduroam.wisc.edu, please do so. Other client devices will seamlessly validate the updated certificate without prompting.
What is eduroam?
eduroam uses end-to-end encryptions to connect you to the internet. This prevents cyber criminals from viewing and intercepting your wireless traffic (e.g., your login username and passwords, the websites you visit, etc.). Learn how to access and set up eduroam.
⚠️ Did you know? When you use “open” networks like UWNet or free Wi-Fi in coffee shops or other public places, your wireless traffic is not secure. The traffic you’re generating can potentially be viewed or stolen by others. Use eduroam instead.
What is changing with eduroam?
The RADIUS/EAP Server Certificate that supports the UW–Madison eduroam service will be updated on March 31 at 5pm. Server certificates allow secure communication between devices on the internet. They are used to encrypt data sent to and from websites, which helps to protect users’ privacy.
Why is this change necessary?
The existing RADIUS/EAP Server Certificate is due to expire on April 8, 2026.
Who will be impacted?
- Devices configured via the eduroam Configuration Assistant Tool or configured with an appropriate reference to the USERTrust RSA Certification Authority root certificate will automatically validate the updated certificate.
- Devices configured manually may receive a request to evaluate and “trust” the updated certificate for eduroam.wisc.edu. Connectivity issues may occur during the update process but will be resolved afterwards.
How can I prepare my device?
