hostapd and fedora19 wifi hotspot

[Gianluca Cecchi]

Hello,
on my laptop (Asus U36sd) I had fedora 17 and configured hostapd
setting bridge on virbr0 and using wpa2.
Reinstalled in fedora 19 with same settings (only changed name of wlan
interface) apparently this doesn't work with this same hw.
I get:
nl80211: Failed to set interface wlp3s0 into AP mode

wireless adapter:
03:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network
Adapter (PCI-Express) (rev 01)

I see that there is a WIFI hot spot function now on Network Manager
(NetworkManager-0.9.8.2-8.git20130709.fc19.x86_64) but I read
somewhere (article dated 2012) that it supports only wep, even if you
could configure wpa.

Questions:
1) Any hint to have hostapd running in f19 or making further debug
actions? It was useful to use it with libvirtd "default" network
(manually created in f19 because not automatically defined as before)
to automatically get routing and dns information.

2) Is still true that NM as shipped in Fedora 19 only supports wep?

Thanks in advance,
Gianluca
