  • Paste the import password that we just copied.
  • Leave the default settings intact.
  • Note: It is not allowed to tick "Activate high security for the private key". The Windows WLAN client currently does not support this function and therefore no connection to eduroam would be possible.
  • Then click Next


  • In the following window, if necessary, click on Next and finally on Finish.

  • Now click on OK.


Note: Now open the same certificate again and install it a second time. This allows us to work around an error in the Windows certificate manager. Do not create a new certificate for this!
