Dear dror,
in this case it was a user fault.
The lines i have posted are the default ones from the image, except the removed # to enable his DAC.
This (and many other issues) should be added to the quick start guide
What issues do you address?
Please consider that you have a very special setup (acces point with hostapd, network without router/switch).
So please be more constructive and open a new topic to tell us what to add / change in the documentation.
Frank
