The WLAN of the University of Bremen is protected. You will not find it if you don't know how.
The German pages
https://wlan.uni-bremen.de/
describe the procedure to configure it. The WLAN has an other subnet as the computers in the
PC room. Therefore, you have to specify username and password of your PC-room account if you
want access to the printers or network shares here.
