Hi! I'm sorry, I only speak English. Our apartment already has a Glasfaser Dose installed in it. We got our router today. We have the appointment tomorrow for someone to hook up the fiber, but I assume we dont need that because we already have a box? We tried to connect the box to the router ourselves, and the router has WLAN but no wifi. We've checked the instruction book and apparently I shouldve gotten an email with a registration link. Do we have to wait until the worker comes (despite him needing to do nothing), or is there anything we can do??
