Unable to connect to AP on a Raspberry Pi

1

I'm trying to setup an access point, using Raling RT5370 USB Dongle on a Debian system, I followed the following tutorial, until "Internet connection Sharing.", I don't want to share internet, so I skip this step. After the reboot I can see the AP, but I can't connect, it seams I can't get an IP address, how can I debug on raspberry to see what's happening or where did I made the mistake?

This is my dhcpd.conf file content:

ddns-update-style none;

subnet 10.10.0.0 netmask 255.255.255.0 {
        range 10.10.0.2 10.10.0.16;
        option domain-name-servers 8.8.4.4, 208.67.222.222;
        option routers 10.10.0.1;
}

The system log:

Do I have to setup something else, because I can see the AP but I can't connect.

Have you configured your wlan0 device to operate in access point (AP) mode? It looks like it may be configured as a wireless client, which could be why it's not getting an IP address set. The lack of an IP address means the DHCP server doesn't have anywhere to listen to DHCP requests coming in.

Note that not all wireless devices are capable of operating in AP mode. Can you confirm your device can act as an AP?
