How do i connect to WIFI while Re-Installing OS with internet recovery?

2014 Macbook pro retina with SSD. Disk-problem which could not be repaired forced me delete the disk. I turned the Mac off and turned it back on getting the "Starting the internet recovery. This may take awhile"- message. After about 10 seconds i get the 4403F-Error message meaning the Mac is not connected to the internet. I don't get how i should solve this though as it never asks me to chose a WIFI-network and then enter a password? I have tree networks within reach (all of which works fine (confirmed this with three different devices).

How do i connect my Mac to a WIFI-network when it is in Internet recovery-mode?
