And the config i am using is :

interface=wlan0
driver=nl80211
ssid=HUB234
hw_mode=g
channel=1
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=12345678
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
disassoc_low_ack=0

Android Wifi clients, wifi dongles, windows systems dont have any problem
connecting to the hotspot but only the apple devices have . I even tried
setting disassoc_low_ack=0 but it doesnt seem to work .
