hostapd (mode master) not found kernel 3.7.10, working kernel lts

Hi,

I'm trying to create an wifi hotspot from my latptop following.

After many tests trying to use a usb in wifi-master mode, so you can use it as Access Point,I saw that in the 3.7.10 kernel is not possible, always hostapd fails.

As in a pc of a roommate (ubuntu 12.10 or 12.04) hostapd work fine, i've tried in the linux-lts and all work fine.

the wifis tested and does not work in 3.7.10

tp-link-wn722n (0cf3:9271 Atheros Communications, Inc. AR9271 802.11n)
ct-wn4320z 0ace:1211 ZyDAS ZD1211 802.11g

why this happens? bug in the drivers?

I was playing around with hostapd last week (so linux 3.7.10). I had to play around with the settings a bit but in the end I managed to get WPA2 working.

Here's the configuration that I used:

interface=wlan0
driver=nl80211
eapol_version=2

ssid=Foonet
#ignore_broadcast_ssid=1
#bridge=br0

#auth_algs=1
wpa=2
wpa_passphrase=somelongsecurepassphrasegeneratedfrom/dev/random
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP
rsn_pairwise=CCMP

channel=6
# b required for Macbook
#hw_mode=b
hw_mode=g

wmm_enabled=1
ieee80211n=1
ht_capab=[HT40+][SHORT-GI-40][DSSS_CCK-40]

Note that "bridge" is commented out.

If that doesn't work, post your hostapd configuration file along with the error messages that you are getting (console output, dmesg output, log files). Check the same on the client if hostapd starts but fails to connect clients.

Oops, sorry I explained bad.

In 3.7.10-1 when I use hostapd with any configuration file, there is a failure to put the wifi in AP mode

for example

hostapd-minimal.conf:

interface=wlan0
driver=nl80211
ssid=test
channel=1 

$ hostapd ./hostapd-minimal.conf 
Configuration file: ./hostapd-minimal.conf
nl80211: Failed to set interface wlan0 into AP mode

When i use linux-ltx, all work fine

Using the kernel-lts, hostapd does not fail to put the wifi into AP mode

So I think that is bug driver / kernel

Ah

It does seem like a kernel/driver bug. I doubt that I have any suggestions to offer that you haven't considered already so I'll just bow out and hope someone else can help.
