Fix eduroam not connecting — authentication failed, can’t join, certificate or profile issues
Technician
Which devices are having problems — Windows laptop, macOS, iPhone/iPad, Android phone? And what exactly do you see when you try to join the eduroam network: “Unable to join eduroam”, “eduroam authentication failed”, “incorrect username or password”, or it just spins and drops?
Also, are you using your university’s eduroam username in the form user@university.edu, and did you ever install an eduroam profile / eduroam CAT installer on this device? That will tell us if we’re dealing with a Wi-Fi profile, certificate, or login issue.
I’m using the university account like
username@uni.edu. I did install something like an eduroam CAT installer the first time I set it up, but I haven’t touched it since. Other students around me seem to connect to eduroam without any problems.
Technician
When eduroam won’t connect, even though other people are on Wi-Fi, the most common causes are:
• A broken or outdated 802.1X / WPA2-Enterprise Wi-Fi profile on the device (wrong EAP settings, inner authentication, or identity format).
• A stale or expired eduroam certificate, especially if CAT or a profile was installed several years ago.
• The account password changed, but the device keeps trying the old password for eduroam and keeps failing silently.
• On phones, features like Private MAC / Private Address, VPN apps or battery savers interfering with eduroam 802.1X authentication.
We’ll first confirm that your devices can still see the eduroam SSID and that campus Wi-Fi works in general, then rebuild the eduroam profile using the correct settings so it actually authenticates again rather than looping on “connecting”.
On Windows it quickly jumps from “Connecting” to “Couldn’t connect to this network”. On Android, it asks for my username and password, then goes back to “Saved” and never actually connects. No specific “wrong password” message though.
Technician
Step A — Check the account and rule out a simple password problem
1) While on guest Wi-Fi or mobile data, sign in to your university’s portal or webmail with the same username@uni.edu and password you use for eduroam. If that fails, we know it’s an account or password issue rather than Wi-Fi.
2) If you recently changed your campus password, remember that eduroam still tries the old password until you update or delete the saved profile on each device.
3) Some universities require a specific eduroam format like
username@campus.XX or a network access token instead of your normal login. If your IT pages mention “eduroam token” or “eduroam credentials” separate from your main password, keep that in mind — we’ll make sure the devices use the right one.Once we’re sure the credentials work in a browser, the next step is to rebuild the eduroam Wi-Fi profile on Windows and Android so it uses the correct 802.1X and certificate settings.
username@uni.edu and password — it works fine. I did change my password about a month ago, but eduroam kept working for a bit after that and only recently stopped.I don’t remember touching any eduroam settings manually. I think I just ran the university’s eduroam setup tool when I first started here and left it alone.

Step B — Fix “Can’t connect to this network” for eduroam on Windows
1) On the laptop, click the Wi-Fi icon > Wi-Fi settings > “Manage known networks”. Find eduroam, click it, and choose Forget so Windows removes the old 802.1X configuration.
2) If you previously installed an eduroam CAT or campus Wi-Fi installer, check Settings > Apps > Installed apps or the Start menu and remove any obviously outdated “eduroam” configuration tool, then reboot the laptop.
3) Go to your university’s Wi-Fi setup page and download the latest eduroam Configuration Assistant Tool (eduroam CAT) or campus-specific eduroam installer for Windows 10/11. Run it and let it create a fresh eduroam profile with the right EAP method (usually PEAP or TTLS), inner authentication, and CA certificate.
4) After the installer finishes, click eduroam in the Wi-Fi list. When prompted, enter your full eduroam identity (usually
username@uni.edu) and your current password, then connect.If eduroam still says “unable to connect” after that, we’ll check advanced settings like anonymous identity and certificate trust, but in most cases the new CAT profile fixes Windows in one go.
After I entered them, it took a few seconds and then connected — I’ve got internet on the laptop over eduroam now. So Windows 11 seems fixed. The Android phone still just says “Saved” and won’t connect though.
Technician
Step C — Fix eduroam “Saved, not connected” on Android
1) On your phone, go to Settings > Network & Internet > Wi-Fi, tap and hold eduroam, then choose Forget. This wipes out the old WPA2-Enterprise configuration.
2) If you previously used an app like eduroam CAT or geteduroam, open it and run the latest profile for your institution. That will automatically fill in the correct EAP method, Phase 2/inner authentication, CA certificate, and domain for eduroam on your campus.
3) If your university doesn’t use CAT, add eduroam manually: set Security to WPA2-Enterprise or WPA2/WPA3-Enterprise, EAP to PEAP (or what your uni specifies), Phase 2 to MSCHAPv2, and enter your full eduroam username and password.
4) Under advanced options, set MAC type to “Use device MAC” instead of “Randomized MAC” if your campus specifically recommends that — some older eduroam deployments don’t like private addresses.
5) Save and reconnect to eduroam. Watch for any “authentication problem” or “incorrect password” pop-ups — that usually means the format of the username or the inner authentication is wrong rather than the Wi-Fi signal itself.
After that, your phone should move from “Saved” to “Connected” on eduroam in a few seconds.
Now the eduroam network connects on my Android phone almost instantly. So both my laptop and phone are online again. I do sometimes see a brief “authentication problem” toast, but it disappears and the connection stays up.
Technician
A few things to keep eduroam Wi-Fi stable as you move around campus:
• Make sure each device (laptop, phone, tablet) has its own fresh eduroam profile — don’t clone old settings between devices.
• Avoid adding manual DNS or proxy settings just for eduroam; let the campus DHCP and DNS handle it unless IT specifically says otherwise.
• If you see frequent reconnects when walking between buildings, check that your devices are not pinned to 2.4 GHz only and are allowed to roam to 5 GHz / 6 GHz where available.
• Keep your OS updated — several Android 13/14 and Windows 11 updates included fixes for WPA2-Enterprise and eduroam 802.1X bugs.
If you ever see eduroam say “Connected, no internet”, that’s a slightly different issue (routing/DNS on campus), but we can also walk through that if it happens.
Is there anything else I should change so that eduroam doesn’t randomly stop working again next semester?
Technician
Step D — Make your eduroam setup future-proof
• Any time you change your university password or eduroam token, immediately update or recreate the eduroam profile on each device instead of waiting for it to break weeks later.
• If your institution uses eduroam network access tokens or app passwords, save those details in a secure password manager so you can quickly reconnect new or wiped devices.
• Once a year (for example at the start of each term), it’s worth forgetting eduroam and reinstalling the latest CAT/geteduroam profile on your main devices to pick up any changes in EAP type, CA certificate, or domain validation.
• Avoid manually changing advanced 802.1X options like inner authentication, anonymous identity, or certificate trust unless a campus guide tells you to — use the official profile where possible.
With that routine, it’s much less likely that eduroam will suddenly stop connecting right before an exam or lecture.
For now everything’s stable — I can roam between buildings and both devices stay on eduroam without dropping, which is exactly what I needed.
Technician
Summary: To fix eduroam not connecting, verify your campus login works in a browser, forget old eduroam networks, then install the latest eduroam CAT/geteduroam profile or follow your university’s eduroam guide so the device uses the correct 802.1X EAP method, inner authentication, CA certificate, and identity format. Finally, avoid random MAC/DNS tweaks unless IT recommends them. If you ever get stuck again — “Unable to join eduroam”, “authentication failed”, or “saved, not connected” — you can open a chat with an expert and we’ll step through it with you in real time.

Quick answer: the accepted fix
Accepted fix when eduroam is not connecting: confirm your university login or eduroam token works in a browser, then forget old eduroam networks on each device, reinstall the latest eduroam CAT/geteduroam profile or campus eduroam setup, and reconnect with the full username@institution and current password. That recreates the correct 802.1X, EAP and certificate settings so “can’t connect to eduroam” and “authentication failed” errors clear.
Why eduroam stops connecting (profiles, 802.1X, certificates, passwords)
Most eduroam not connecting problems are not caused by the campus Wi-Fi itself, but by the eduroam configuration on your device. Common triggers include: changing your university password without updating the saved eduroam password, keeping an old eduroam profile that uses outdated 802.1X / EAP settings, or expired CA certificates installed years ago by a legacy CAT installer.
Because eduroam is a WPA2/WPA3-Enterprise network using 802.1X, your device has to validate the right authentication server and present the correct identity. If anything in that chain is wrong — from the user@realm format to the inner authentication method — you see loops like “Connecting → Saved” or “Can’t connect to this network” while classmates connect normally. Re-installing the official eduroam profile from your institution or the eduroam Configuration Assistant Tool (CAT) usually refreshes all these settings in one go.
How to check if it’s eduroam, your device, or your account
To quickly narrow down an eduroam not working issue, separate it into account → device → Wi-Fi network:
First, test your university credentials by signing into the campus portal or email over guest Wi-Fi or mobile data. If that fails, fix the account or password before touching Wi-Fi. Next, try connecting a second device (phone, tablet, or borrowed laptop) to eduroam using the same username@institution. If only one device fails, delete and recreate the eduroam Wi-Fi profile on that device. If every device with your account fails while others work, the problem is more likely to be account-side (eduroam tokens, access blocked) and you should contact campus IT.
Eduroam not connecting — quick troubleshooting tips
Check your campus login, then rebuild the eduroam profile with the correct EAP and certificate settings.
Fast path: verify your university account or eduroam token works in a browser → forget eduroam on each device → install the latest eduroam CAT or geteduroam profile for your institution → reconnect with your full eduroam identity (username@realm) and new password → on phones, disable conflicting settings like random MAC or VPN if your campus Wi-Fi guide recommends that. In most cases, this resolves “unable to join eduroam”, “saved, not connected”, and random authentication failed errors.

FAQ
Why is eduroam not connecting on my laptop or phone?
Most of the time eduroam won’t connect because the device’s Wi-Fi profile is outdated or misconfigured. Common causes are using an old password, incorrect username@institution format, wrong EAP/inner authentication, or missing/expired CA certificates. Forgetting eduroam and installing your university’s latest eduroam CAT/geteduroam profile usually fixes this.
How do I fix “Can’t connect to this network” or “Unable to join eduroam”?
Start by confirming your campus login works in a browser. Then, on the device, forget eduroam so the old 802.1X settings are removed. Install the official eduroam setup tool for your university (CAT/geteduroam or a campus installer) and reconnect using your full eduroam identity and current password. If you still can’t join after that, contact your university IT to check for account blocks or realm-specific requirements.
What username and password should I use for eduroam?
Most institutions require that you sign in with a scoped identity such as username@university.edu or a dedicated eduroam access token rather than just your short username. The password is either your normal campus password or a separate eduroam token password, depending on your university’s guide. Always follow the exact format shown in your institution’s eduroam setup instructions.
When should I contact campus IT about eduroam issues?
If you’ve verified your credentials in the portal, reinstalled the eduroam profile, and still see authentication failed or can’t connect on multiple devices, it’s time to contact your university IT helpdesk. They can check for account restrictions, device limits, or specific requirements like anonymous identity, certificate pinning, or MAC address conflicts on the eduroam network.
