I am running a Wifi network with a fritzbox 7360 and all my apple devices (apple tv old and new, MacbookPro, mac mini, iPhone, iPad) can connect just fine. Recently I bought apple time capsule 3TB which won't join my local wifi for unknown reasons. I ran several resets, checked configuration and read all I could found on the internet. Connectivity and placement seems fine as well (I checked with other devices).
Below are my settings. Can somebody help?
