Windows 10 - Manual Configuration

This guide describes how to manually configure Wi-Fi access to the UHH eduroam network on Windows 10 or later using native Windows components.

Manual configuration of the eduroam Wi-Fi connection on Windows 10 involves numerous settings windows; therefore, for clarity, a summary of the necessary configuration steps follows without illustrations.

Configuring the Wi-Fi interface

  1. Download the root certificate “Universität Hamburg Internal CA”
  2. Install the root certificate by double-clicking the downloaded file “cacert.crt”—follow the operating system’s instructions if necessary
  3. Right-click the network icon in the bottom-right corner of the taskbar
    • Select “Open Network & Internet Settings”
    • Select “Wi-Fi” in the left column
    • In the right column, select “Network and Sharing Center”
  4. Select “Set up a new connection or network”
  5. Select the option “Connect to a wireless network manually”
  6. Click the ‘Next’ button
  7. Network name: eduroam
  8. Security type: WPA2-Enterprise
  9. The checkbox for “Start this connection automatically” is automatically checked
  10. Click the “Next” button
  11. Click “Change connection settings”
  12. Select the “Security” tab
  13. Select “Microsoft: EAP-TTLS” as the network authentication method
  14. Select the “Settings” button
  15. Replace the ‘anonymous’ entry under Identity Protection with “anonymous@uni-hamburg.de”
  16. Under “Connect to the following server,” enter “roamrad.rrz.uni-hamburg.de”
  17. Select “Universität Hamburg Internal CA” as the trusted root certificate authority
  18. Check the box next to “Do not prompt the user if the server cannot be authorized”
  19. Confirm by clicking the ‘OK’ button
  20. Click the “Advanced Settings” button
  21. Select “User Authentication” as the authentication mode
  22. Select the “Save Credentials” button
  23. In the input window, enter the user ID (b******) with the extension “@uni-hamburg.de” and the corresponding password
  24. Confirm with “OK”
  25. Close all open input windows

Establishing the Connection

  1. Left-click the network icon to display the list of available networks
  2. Select the “eduroam” entry and click “Connect”
  3. The message “Network requirements are being checked” disappears after a short time and
  4. the ‘eduroam’ Wi-Fi network is displayed as “Connected, secure”
  5. In the future, the laptop will automatically connect to the eduroam Wi-Fi network as soon as it is within range with the Wi-Fi interface enabled

Change or correct the configuration

Once a configuration has been created, it cannot be changed or corrected. If, for example, the password was entered incorrectly, Windows 10 will not establish a connection to the eduroam Wi-Fi network. In this case, you will not be given another opportunity to enter a new password. The same problem occurs if a password change was made via the RRZ portal. In these cases, the existing configuration must be completely deleted and then recreated. To do this, please proceed as follows:

  1. Open the Windows Command Prompt: Type “cmd.exe” into the Windows search bar and press Enter
  2. Delete the configuration using the command “netsh wlan delete profile eduroam” and confirm by pressing Enter
  3. Reconfigure the eduroam Wi-Fi access as described in Section 1. Configuration of the Wi-Fi Interface
