ctrl_iface for WPS

["Jan Tröster"]

Hello together,

I´m trying to set up an AP with the possibility for clients to connect via wps_pbc.
The AP is working so far, but when I start with debugging it told me "ctrl_iface not configured!".
Has anyone a solution for that problem?

Apart from this point does anyone know why I had to comment out "ieee80211n=1" and "ht_capab=[HT40][SHORT-GI-20][DSSS_CCK-40]" to get the AP running in hostapd v2.7-devel-hostap_2_6-1199-gee522d2?
