Hi,

Using Ubuntu Server 12.04 LTS with hostapd (v0.7.3) since more 50 days without any problem.
Server rebooted this morning after packages updated.

Now my wifi devices (thinkpad, android phones ...) cannot get connected. 

Hereafter are the syslog messages :

/etc/hostapd.conf :
interface=wlan0
driver=nl80211
ssid=xxxxx
hw_mode=g
channel=9
ieee80211n=1
max_num_sta=10
macaddr_acl=0
dynamic_vlan=0
dump_file=/tmp/hostapd.dump
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
country_code=FR
own_ip_addr=10.1.1.254

The AP is open, no WEP.

I make some search on web .. but nothing positive.
I think the problem is "deauthenticated due to inactivity" 

Is anybody have a solution ?

Many many thanks
Phil.
