Hi. I need your help. We’ve been using our Speedport Smart Router for only a month and suddenly today, I was surprised that all my gadgets can’t detect the network. 

i tested the connection thru the Help App and it’s telling me that there is no problem with the Internet Connection but why can’t I connect to my router? I need your help please because I know how to speak Deutsch but not enough to explain to them what is happening. 

thank you.
