Access to WLAN

As a member of the University of Hamburg, you can connect to WLAN access points of the University via

  • VPN (Virtual Private Network)
  • eduroam (education roaming)

Guests can use eduroam or request a temporary guest account. We recommend using eduroam if you have a valid account from a participating institution.


You need the Cisco AnyConnect VPN Client to use the University's VPN service. To download and install the client, go to the webpage VPN of the computing center (in German) and follow the link in the section Installation und Verbindungsaufbau for the operating system you are using.


Once the client is installed on your computer,

  1. if available, select the Wi-Fi network UHH (you can also use networks from other providers, for example, your WLAN at home)
  2. start the Cisco AnyConnect VPN Client,
  3. login with your UHH account.

An advantage of using VPN is that your computer obtains an IP address within the network of the University. As a result, you have access to all services that are constrained to the University's network.


For Mac OS and Windows 8 or higher, the computing center provides configuration scripts (see section 802.1X-Authentifizierung für UHH-Mitglieder on the WLAN webpage of the computing center).


When connecting to eduroam under Ubuntu, apply the following setup:


Authentification WPA2
Encryption AES
EAP (Extensible Authentication Protocol) Tunneled TLS
External identity Diese E-Mail-Adresse ist vor Spambots geschützt! Zur Anzeige muss JavaScript eingeschaltet sein!
Certificate Deutsche Telekom Root CA 2
Authentification method PAP
Login <user> (your UHH acount)


The Telekom certificate can be found under the following path:



  • No WLAN is available. - WLAN might be deactivated on your computer (beware, some Laptops have manual switches) or you are simply out of reach of a rooter (unlikely, but possible).
  • I started the Cisco client, but I cannot connect. - First you have to select one of the available Wi-Fi networks, e.g. UHH (usually, there is a sympol on the taskbar on which you can click)
  • I am connected to VPN, but I can still not browse the internet. - Make sure that you correctly configured the proxy server settings of your browser (see, for example, the Windows instructions, step 4).
