Instructions to set up WLAN access under Windows 7

Note

Please note that the following instructions describe how to set up the Eduroam network using the CAT configuration tool.

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

For security reasons, the WLAN 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 WLAN password once 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.

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 7) and start the download.

Step 4

Launch the downloaded application (eduroam-W7-Universitaet_Bremen-eduroam.exe)


The installation starts, click 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 password and confirm your entries with Enter.

 

Step 5

The connection is now established. 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.

Instructions for manually setting up WLAN access under Windows 7

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 "Open 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 then 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

Click the Connection Manager icon again at the bottom right of the screen (see step 3), select the WiFi "eduroam" and then 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 as the 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 then 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.
