eduroam (education roaming) is the secure, world-wide roaming access service developed for the international research and education community.
The eduroam service is the preferred secure wireless network for faculty, staff and student personal devices. This network service is provided on Ohio State campuses to provide the ability for visiting faculty and students of participating institutions to easily gain secure network access utilizing their home institution credentials. It also provides Ohio State faculty, staff and students that will be visiting a participating institution the ability to pre-configure their devices for eduroam access, making gaining secure access while away automatic. Ohio State faculty, staff and students can configure their devices for eduroam at wireless.osu.edu.
IMPORTANT: Instructional Guides for re-onboarding to eduroam
In fall 2026, Ohio State is updating the security certificate used to verify our Wi-Fi network. For MITS-managed devices, no action is required—IT will complete the update automatically. Requirements for other Ohio State provided devices may vary by department. To ensure your personal devices continue connecting without interruption, you will need to re-enroll your device now so it is properly configured. If you enrolled after July 9, 2026, your device has already received the new certificate, and no further action is required.

Frequently Asked Questions
What happens if I don't re-onboard my device?
Your device may no longer connect to eduroam once the security certificate is updated after October 13.
Can I wait until my device stops connecting?
You can, but re-enrolling now will help prevent an interruption and ensure your device is properly configured before the update. If you do not re-onboard by October 13, it will require more steps, and you may need assistance from IT support.
When do I need to re-enroll my device?
Re-onboard your device before the certificate update takes effect on October 13th to avoid an interruption to your eduroam connection.
Do I need to re-enroll my device?
If you use a personal device to connect to Ohio State's eduroam Wi-Fi and enrolled before July 9, 2026, you should re-onboard your device using the instructions for your device type. If you enrolled after July 9, 2026, no further action is needed.
Do I need to re-onboard all my devices?
Yes, each personal device that connects to eduroam may need to be re-enrolled individually.
I enrolled in eduroam recently. Do I need to do this again?
If you enrolled after July 9, 2026, your device already has the new security certificate, and no further action is required.
Are Ohio State-provided devices affected?
For Managed IT Services (MITS) managed devices, no action is required. IT will update the security certificate automatically. Requirements for other Ohio State-provided devices may vary by department. Please check with your local IT for department specific instructions.
How do I know whether my Ohio State device is MITS-managed?
All departments who are Managed IT Services partners are listed on this page. If you are part of a MITS-managed organization, you will still need to re-onboard your personal devices.
What if I have a device that is not listed in the instructional guides?
Contact the IT Service Desk or your local IT support for assistance. The IT Service Desk is available to support you 24/7. Request IT support online or call the Service Desk at 614-688-4357 (HELP).
Why is Ohio State changing the security certificate?
When you first connected to Ohio State’s network, your device was configured to recognize and trust the network as a safe place to connect. It does this by verifying a digital security certificate, which serves as proof that the network is legitimate. These certificates are issued by trusted certificate authorities and have traditionally remained valid for several years.
However, the certificate industry is significantly reducing certificate lifespans, meaning they may soon need to be renewed as often as every 40 days. To avoid requiring frequent updates on your devices, Ohio State is moving to a new certificate model that provides longer-term trust. Your device needs to be re-onboarded so it recognizes Ohio State’s new security certificate.
What is a security certificate?
The security certificate is used to help your device verify that it is connecting to the legitimate Ohio State eduroam network.
Will I need to enter my Ohio State username and password?
Yes; this is outlined in device-specific instructions.
What if I can't connect to Wi-Fi to complete the re-onboarding?
You can use cellular service or Ohio State’s open network, WiFi@OSU, to re-onboard before Oct. 13.
