Instruction to set up WLAN access under Windows 10

Note

Please note that we can only offer help with problems on officially supported operating systems.


When prompted for user data, be case-sensitive and enter your username (not an alias) including @uni-bremen.de.

For security reasons, the WiFi password is not the same as the password of your Uni account. Students set the
Password automatically when activating the Uni-Account, other users have to set up the WiFi password in the onlinetools.

If you prefer manual setup, you will find manual setup instructions further down this page.

If there is a problem, please contact us by e-mail at wlan@uni-bremen.de or at the IT-Servicedesk.

Step 1

First you have to download the CAT configuration tool, to do this open the item Network Connections in the Windows taskbar and connect to Wlan 'Uni-Bremen'.


Alternatively you can download the Cat-Tool via your Wlan at home or mobile data such as a hotspot (in this case continue from step 4).

Step 2

A login window will open in your browser, click on the link to the CAT-Eduroam configuration tool or use the link wlan.uni-Bremen.de/cat.

 

Step 3

In the following window, select the CAT configuration tool for your device/OS (in this case Windows 10) and start the download.

 

Step 4

Launch the downloaded application (eduroam-W10-Universitaet_Bremen-eduroam.exe)


The installation starts by clicking on next

In the following window you will be asked for your login data for the Eduroam network, enter them in the form username@uni-bremen.de and the corresponding WiFi-password and confirm your entries with a click on install

Step 5

The connection is now set up. If the connection is not established automatically, select the eduroam network manually and connect by clicking Connect.

Troubleshooting

If no connection is established, this can have various causes:

 

  •     The WLAN antenna of the notebook is deactivated. Usually, it is reactivated at the push of a button.
  •     If there is no access point with the eduroam network in the vicinity, the location must be changed.

If problems persist, our diagnosis page may be able to help.

Setup Guide for Manual Wifi Access on Windows 10

Step 0

Please make sure to delete existing connections to eduroam before you start the manual setup. To do this, open the network settings by clicking on the network icon in the taskbar - the network settings - go to WLAN - search for eduroam and then click on - Do not save

Step 1

Make sure that the Wlan hardware of your computer is activated. Click on the icon for the connection manager at the bottom right of the screen. Now click on "Network and Internet Settings".

Now click on "Network and Sharing Center".

Step 2

In the Network and Sharing Center, click on "New Connection or New Network Setup".

Step 3

Select "Connect manually to a wireless network" and click "Next".

Step 4

In this dialog, enter the settings as shown in the illustration on the right. Then click "Next".

Step 5

Click on "Change connection settings" and in the new window on the tab "Security".

Step 6

For "Select a network authentication method:", select "Microsoft: Protected EAP (PEAP)". Then click Settings.

Step 7

Check "Connect to these servers" and enter "radius.wlan.uni-bremen.de" in the corresponding field.


Check the box "T-TeleSec GlobalRoot Class 2".

 

For "Select authentication method:" click on "Secure password (EAP-MSCHAP v2)" and then click on "Configure...".
In the "EAP-MSCHAPv2 Properties" window, remove the check mark and confirm the dialog with "OK".

Finally activate the item "Activate identity data protection" and enter "eduroam" in the field behind it.

Step 8

In the "Security" tab, click on "Advanced settings" and select "User authentication" as the authentication mode (tab "802.1X settings").


Now enter your access data. If you have entered your access data correctly here, the entry in step 10 is omitted.


Close this dialog with "Ok".

Step 9

At the bottom right corner of the screen, click the Connection Manager icon again, select the WLAN "eduroam" and click Connect. If a connection attempt has already been made, first click on "Disconnect" and then on "Connect" to make the changes effective.


Now the dialog for entering the access data appears. Enter the user name of the university account followed by "@uni-bremen.de" and the WiFi-Password. After a click on "OK" the connection should be established after a few seconds.

On some computers we have observed that user name and password have to be entered several times before the connection is established. Unfortunately, we have no influence on this peculiarity of Windows. If necessary, please enter your access data several times before you suspect another problem.

Step 10

If a query about the location of the computer appears, you should select "Public Network" to not activate eduroam-wide file shares at the university.

Troubleshooting

If no connection is established, this can have various causes:

 

  •     The WLAN antenna of the notebook is deactivated. Usually, it is reactivated at the push of a button.
  •     If there is no access point with the eduroam network in the vicinity, the location must be changed.
