deauthenticated due to local deauth request HOSTAPD
<p>i have set AP in respberry pi 2 model B with TP-LINK Dongle,and the TL-WN772N 
now the problem is that when i try to connect with my respberry pi dongle it's throw an error:</p>

<p><strong><em>wpa_sm_step() called recursively.</em></strong></p>

<p><strong><em>IEEE 802.11:deauthenticated due to local deauth request.</em></strong></p>

<p>and what in my hostapd.conf file has:</p>

<pre><code>interface=wlan0
driver=nl80211
ssid=SRG
hw_mode=g
channel=6
macaddr_acl=0
ignore_broadcast_ssid=0
wpa_key_mgmt=WPA-PSK  
wpa_pairwise=TKIP
rsn_pairwise=CCMP
wpa=2
auth_algs=1
wpa_passphrase=1234567890 
</code></pre>

<p>and when i removed its security , then it works fine but here in my scenario i need security ? can somebody tell me how can i over come this issue ?
any help will be appreciated...<strong>Thanks</strong></p>
