--- Comment #1 from Raphael raphael.nestler@gmail.com --- It doesn't happen anymore. The only thing that I could imagine was the reason is because of the connected WiFi network, which had an SSID which contained some special characters. But I couldn't reproduce this issue with setting up a hot-spot with a similar SSID.
