Hello,

I have a very odd issue. Can connect to the internet fine via the laptop but whenever I connect any mobile device to the WiFi, I get a 'Sign-in to WiFi network' prompt. Clicking on it takes me to kundencenter.telekom.de/festnetz/services/walledgarden/bng/wg54-landing-page.xhtml. There I get prompted to enter my username and password after which I get a message asking me to call customer service. Not sure what's going on. Would really appreciate if someone from the community can please help.
