The Technische Universität Berlin offers comprehensive coverage with Wireless Lan (WLAN) on its campus. TU members as well as members of other institutions that are part of the eduroam network have access to the internet and (sub-) networks of the TU Berlin everywhere on campus.
Two configurations are available under the following URL for setting up the WLAN on computers or mobile devices: https://cat.eduroam.org/
Connection to the WLAN "eduroam" after installation and setup under https://cat.eduroam.org/
Open spaces outside the buildings, stairwells and warehouses are not equipped with WLAN access points, so the WLAN connection there can be patchy.
By checking the server certificate, the authenticity of the authentication servers is ensured, which checks your user name and password. This prevents your password from being read by third parties.
Note that the implementation of this check in some devices or more precisely the drivers of the respective WLAN cards is not correct, so that connection problems may occur. In these cases, we recommend updating the driver of the WLAN card and, if necessary, requesting support from the respective manufacturer.
For Andoid 7+, you can also download the APK directly from our website. For older Android versions, you must activate the installation of APK files under "Settings > Security > Unknown sources". From Android 7 onwards, you will be explicitly asked during installation whether the app may be installed.
Visitors to the TU Berlin, e.g. visiting academics, can also use the eduroam network with the account information of their home university, provided that the university belongs to the eduroam network. For the configuration, please use the instructions of your home institution.

The ZECM offers both 2.4 GHz (802.11g/n/ac/ax) and 5 GHz (802.11a/n/ac/ax) at all TU locations, each with a theoretical signaling rate of up to 9.6 Gbps. The real usable data rate is significantly lower due to, among other things, the uplink being limited to 1 Gbit/s, protocol overhead and error corrections.
This maximum data rate is shared by all users of the access point. The 5 GHz band is currently less used and therefore higher data rates can be achieved in this band. We recommend that all users give preference to this band if their terminal supports this standard.
Theoretically, they can connect any device that supports the 802.1X authentication standard (EAP-PEAP with MS-CHAPv2). Please note, however, that the ZECM customer service only supports the operating systems listed under "HowTos".
Intel chipsets such as the Intel Ultimate-N 6300 WLAN card can cause problems with 802.11n connections under Linux and Windows.
Such chipsets are installed in numerous Lenovo models (T410, T410s, T510, W510, X201, T420, T420s, T520, W520, X220, W701, W701ds). A new driver or, in the case of Linux, a kernel update can help.
Another workaround is to switch off the n standard. This is done under Windows in the driver configuration and under Linux with the command:
echo "options iwlwifi 11n_disable=1" | sudo tee -a /etc/modprobe.d/iwlwifi.conf
With Linux, it is important to shut down the PC completely afterwards (experience has shown that a simple restart is not always sufficient) and to start it up again.
Please note that by doing this, you are deactivating the n-standard for all networks and not only for eduroam and this can lead to slower connection speeds. You can undo it with the following command:
echo "options iwlwifi 11n_disable=0" | sudo tee -a /etc/modprobe.d/iwlwifi.conf
Sometimes smartphones/tablets have a problem authenticating themselves in the TUB WLAN. This can be due to a space after the user name, for example, which is automatically added by the keyboard app.
Please make sure during configuration that such a space is not automatically inserted and check the user name in case of connection problems.
If you receive either of the above messages, your browser has tried to install a certificate.
This is not necessary or desired in the course of the Eduroam setup.
The certificates must be installed for your operating system. Download the corresponding certificate file to your computer (right-click on the file reference, in the pop-up menu "Save target as...") and then install (double-click on the downloaded file, "Install certificate...", "Next", "Next", "Finish").
