The wireless network of the TUHH can be used by students, staff and guests for applications in research and teaching. To prevent an abuse of the networks and to ensure a high level of security for our users, access to the network is subject to certain conditions and restrictions.

In any case, access to the network is only granted after successful authentication of the user. This means everyone needs to log in with his or her personal username and password. The login procedure must be made in a way passwords can not fall into the wrong hands. As a result, the network differs from wireless networks used in the home environment.

The stability of wireless network connections depends a lot on the characteristics and state of your device. Before you complain about the wireless network of the TUHH, please check whether the cause is your own device (eg outdated device drivers, inconvinient location of the wireless antenna, misconfiguration, see Common Problems).

Generally, a wireless connection is not as stable as a wired connection. Especially in the 2.4 GHz band there are a variety of competing radio services (eg Bluetooth, cordless DECT phones) or noise sources (eg microwaves, reflections / interference). The available bandwidth is shared by all end devices in a radio cell. For these reasons, no fixed bandwidth can be guaranteed in the Wi-Fi; it can vary greatly depending on the circumstances.

The RZ has, for reasons of security, the "souvereignty" over the wireless infrastructure of the TUHH. This means departments and institutions of the TUHH are not allowed to set up their own wireless network infrastructure, except this is absolutely required and has been officially agreed with the RZ.

Wireless networks at the TUHH (SSIDs)

The wireless network of the TUHH uses different identifiers, known as SSIDs. These IDs are publicly broadcastet and therefore should show up on all operating systems automatically. The wireless network is a so-called infrastructure network which means access is provided by wireless access points. This is distinguished from ad hoc networks which set up a connection directly between multiple computers. Refer to the appropriate settings of your device.

Each device requires an IP address to be able to connect to the wireless network. This is assigned automatically (dynamic IP Addresses via DHCP). If your wireless adapter is configured to use a static (i.e. fixed) IP address it is not possible to establish a connection to the wireless networks of the TUHH.

The following network IDs are broadcasted. For further information click on the appropriate link:

Network coverage and availability

Almost the whole campus, the TUHH buildings in the Harburger Schlosstraße and the Technology Center Hamburg-Finkenwerder (THF), Neßpriel 5, are covered by the wireless network:

  • Building TYS8  (Theodor-Yorck-Straße 8)
Additional access points (AP) are planned.

Usage for members of the TUHH

Students and staff can log into the wireless network using their Kerberos account. Therefore everybody can use the same username und password for all services of the RZ.

For security reasons, a distinction is made in the wireless network between students and staff. Both user groups have different access rights for use of the wireless network/VPN-Service. The specific restrictions can be found in the explanation of the wireless networks/SSIDs.

Usage for members of other universities in Hamburg

For the University of Hamburg, HafenCity University and the HAW Hamburg, access to the VPN service of their home institutions is enabled in the wireless network VPN/WEB.

Otherwise, DFNRoaming/eduroam is possible.

Usage for guests

For events/fairs/conferences, the host department may apply for an event network. As a guest you will get more information from your host.

The TUHH participates in the DFNRoaming and therefore in the eduroam Projekt as well. Guests from institutions, which are also also part of DFNRoaming/eduroam, can log into SSID eduroam with the account from their home institution as usual.


Generally when purchasing NICs or notebooks: the wireless adapter should be compatible with the 802.11n standard and carry the WiFi certificate. In the Audimax 1 and the library the standard 802.11a is supportet as well.

It may happen that there is a little switch at your laptop or a key combination which could be used to turn the wireless adapter on and off (please refer to the manual). If you are unable to establish a wireless connection, please check the position of such a switch.

Please make sure your wireless adapter is also running with the newest device drivers.


In europe, radio communication on the 2.4 GHz ISM band is royalty-free, but the transmission power is limited. Access points and wireless clients can send with a power of up to 100mW. In comparison, the transmission power of mobile phones in Germany is about 2 watts. Mobile phones therefore use a sgnificantly higher power than wireless adapters according to the IEEE 802.11a/g/n standard.


Please make sure that your device has the latest patches installed, that you are not using more than one anti-virus program and that no "unblocker" is active.
(Unblocker are programs which can unlock content, that is blocked in one country, but not another.)
