Step-by-step description[Bearbeiten | Quelltext bearbeiten]
What to do?[Bearbeiten | Quelltext bearbeiten]
- Create new network certificate in the service portal
- Set up Eduroam with the new network certificate
- If necessary, remove the Webauth network from the preferred networks
Step-by-step instructions[Bearbeiten | Quelltext bearbeiten]
Create network certificate[Bearbeiten | Quelltext bearbeiten]
To use Eduroam you need a network certificate at the University of Paderborn. In the first step we have to create and download this.
- The "Webauth" network can be used for this process. “Webauth” is only intended for this setup process and will log you out again after a short time.
Go to the service portal and log in with your university account.
- Open the “Netzwerkeinstellungen” under Benutzerverwaltung
- Click "Neues Zertifikat erstellen".
- Give the certificate a unique name (Ex: MacBook)
- Select "Version 1" as the file format.
- Then click on "Neues Zertifikat zusenden".
- A new network certificate has been created for you.
- First copy the Importpasswort to the clipboard.
- Now click on "Netzwerkzerifkat herunterladen".
Install network certificate[Bearbeiten | Quelltext bearbeiten]
Open the certificate.
- Enter the import password for the certificate.
- We just copied it to the clipboard.
- Alternatively, we can type it from the service portal.
- We continue with "OK".
Set up Eduroam[Bearbeiten | Quelltext bearbeiten]
- The certificate is imported, now we can set up Eduroam.
- To do this, click on the WLAN symbol in the bar at the top and then continue by clicking on Eduroam.
- Use the first button to select your certificate - It is <username>@uni-paderborn.de.
- Be sure to leave the field for user name and password blank!
- Then click "OK".
Do you use an older Version auf macOS?
- Click the first button and select EAP-TLS mode.
- Then click on the second button and select the network certificate you just created as the identity. It is <username>@uni-paderborn.de.
- Be sure to leave the username field blank!
- We continue by clicking on "Connect".
- Click on "Fortfahren".
- MacOS now informs us that a change has been made to our computer.
- To confirm, enter the password for your Mac and then click Allow.
- This query can appear up to three times. Enter the password for your Mac every time.
Remove WLAN network Webauth[Bearbeiten | Quelltext bearbeiten]
- Now we're actually done - Eduroam is set up and can now be used.
- However, if you have used the Webauth WiFi network on your Mac, you should definitely remove it, otherwise problems may arise.
- To do this, we click on the WiFi symbol above again.
- By clicking on “System Settings "Netzwerk öffnen..." we go to the settings.
- Here we click on "More options..." at the bottom.
- The WLAN networks to which our Mac was already connected are now displayed in the preferred networks.
- Search for "Webauth" in the list and select it with one click.
- We then remove it by clicking on the minus symbol.
- Confirm the changes made with "OK".
- Then click "Anwenden" at the bottom.
Troubleshooting[Bearbeiten | Quelltext bearbeiten]
If you are unable to connect to Eduroam as described above, follow these steps.
Remove the WLAN profiles for Eduroam and Webauth as described above.
- Click on the WiFi icon in the bar at the top.
- Select "Connect to another network...".
- From macOS 12 - Moneterey this may look different.
- Click on the WiFi icon.
- Click "Other Networks".
- Click "Other...".
Set up the network with the following settings:
- Network name: eduroam
- Security: Company-wide WPA2
- Mode: EAP-TLS
- Identity: Select your installed network certificate. The name ends with “@uni-paderborn.de”.
- Username: Be sure to leave this field blank.
Now click on Verbinden.
