- Your device must support WPA3-Enterprise.

WiFi configuration settings

Using the manual settings described here is only recommended in special cases or if the automatic setup does not work!

1. Press "Start" (or press the Windows key) and search for "Control Panel".
2. Open Control Panel → Network and Internet → Network and Sharing Center and then "Set up a new connection or new network".

3. In the "Set up a connection or network" dialog, select "Connect to a wireless network manually".

4. Enter the basic network and security settings in the "Manually connect to a wireless network" dialog.
- Network name: eduroam
- Security type: WPA3-Enterprise (some WiFi driver only show WPA & WPA2 Enterprise)
- Encryption type: AES
Leave the remaining settings as they are and click on "Next".

5. In the next dialog, select "Change connection settings".
6. In the "Wireless network properties" dialog, select the "Security" tab, "PEAP" should already be selected as the method for network authentication. Now select the "Settings" option.

7. In the "Properties for protected EAP" dialog activate "Verify server identity using certificate" check, if this is not yet the case.
- In the "Connect to the following server" field, enter radius.uni-marburg.de.
- As Trusted root certification authorities, activate HARICA TLS RSA Root CA 2021.
- Authentication method: EAP-MSCHAPV2
  - Remove the tick next to Configure authentication method
- Activate "Activate identity protection" and enter eduroam-2026 in the input field.

 

8. Confirm the dialog for protected EAP with OK. Back in the "Wireless network properties" dialog, select "Advanced settings".

9. In the "Advanced settings" dialog, activate "Specify authentication mode" and select "User authentication".

10. Confirm the "Advanced settings" dialog with OK and the "Wireless network properties" dialog also with OK.
- If the please-wait mouse pointer does not disappear, move the mouse and continue anyway.
11. Click on the WiFi symbol to log in to eduroam and enter your username and password:
- Students: username@students.uni-marburg.de
- Staff: username@staff.uni-marburg.de

Please note: The eduroam username is not an e-mail address, despite the similarity. Aliases such as firstname.lastname@staff.uni-marburg.de do not work!

FAQ

  • Which WiFi adapter is built into my device?

     1. Click “Start” (or press the Windows key) and search for “Device Manager”.
     2. Open Device Manager and expand the “Network adapters” category.
     3. There should now be several entries there; look for the one that includes “Wi-Fi” or “Wireless LAN”.
      - Example: Intel(R) Wi-Fi 6E AX211 160MHz

  • What version of the WiFi driver is currently installed?

     1. In Device Manager under “Network adapters” right-click the installed WiFi adapter and select “Properties”.
     2. On the “Driver” tab, you can see which driver version is installed and when the driver was released (driver date).
      - Note: The driver date is not the date you installed the driver.

  • How do I update the WiFi driver?

     1. Find out the manufacturer, adapter model, and driver version for your device.
     2. Now search for the WiFi adapter in your web browser and add “driver” at the end.
     - Example: Intel Wi-Fi 6E AX211 driver
     3. Find and open the manufacturer’s website and check if a newer version is available.
     Note: Please download the new driver exclusively from the manufacturer’s website; otherwise, you may inadvertently install malware!
     4. If you can’t find a compatible driver, many manufacturers offer support tools for automatic detection and installation.
     - Example: Intel Driver & Support Assistant (Intel DSA)

If the connection does not work, contact the helpdesk team.
Please include your username (uid) and the WiFi-MAC-address of the device with your inquiry.
