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 changing?
The RADIUS/EAP Server Certificate that supports the UW–Madison eduroam service will be updated on March 31 at 5pm.
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.
