Hello and happy holiday!

I'm moving to a new apartment and have set up a technician appointment to set up my internet. However due to delay on the landlord side I'm not in the new apartment yet but they are willing to open the door for the technician to come in.

My question is, do I need to be present at the appointment and do I need to bring the router with me? My router is Telekom Router Speedport Smart 4 which I own.

Thank you!
