After installing hosapd what else do I need to install or configure to make rt5370 an AP?

[조정흠]

Hello list,

As of today, maybe for about 2 weeks, I've compiled "openssl(1.0.1)",
"libnl(1.1.4)" and "hostapd(0.7.3)" on uClinux(2.6.27) with the modules
below.

rt2800usb.ko
rt2800lib.ko
rt2x00usb.ko
rt2x00lib.ko
mac80211.ko
cfg80211.ko
compat.ko
compat_wireless.ko

My device is RT5370.

So, now I can find the SSID I wrote on the hostapd.conf.
But I didn't succeed to connect to my device with my android phone.
Authentication fails until now.

Now I wonder what else do I need to do more?
