THE SHORT ANSWER
An unfamiliar device is not automatically an intruder.
Your Wi-Fi list can include your own devices, guests or devices whose names you do not immediately recognize. Examples include smartphones, TVs, printers, repeaters and smart-home devices.
Before assuming an attack, identify the entries one by one. If a device still cannot be explained after checking, take a closer look at your FRITZ!Box security settings.
