Interface Stuck on initializing

Hi al,

I am trying to install hass.io on a raspberry pi 3 b and the bass.io interface is stuck on initializing. I have tried multiple webbrowsers on multiple devices and after 24 hours stille nothing changed. Anybody any Idea how to fix it?

Hook a monitor up to the HDMI port to see if there are any error messages.

There is it saying:

Wlan0: link is not ready
Brcmfmac: power management disabled

The raspberry is connected with ethernet and i can see it in my router.
