Trouble cracking AP without station

[Flekain]

Hi there
I'm trying since a couple of day to crack my best friend AP (He is OK)
His ISP is "Orange" a french ISP, and is Modem is a Livebox.
Personnaly, I have a rt61 based device.

The problem is: He is never connected using WiFi, but WiFi is [ON] on his modem.

So I tried the fake authentification attack, before trying to inject packets, but it seems to fail a little bit:

I see "Authentification sucessfull" in aireplay, and my station appears in airodump-ng on the line "STATION" I see my mac address...
But fake auth window show this:

20:25:55 Sending Authentication Request (Open System)
20:25:55 Authentication successful
20:25:55 Sending Association Request
20:25:55 Denied (code 12), wrong ESSID or WPA ?

And this message appears every second...

I ignored it, and tried to continue cracking my AP, but when I try the package inject attack, I got nothing ARP (just some ACK)

Can you help me please ?

Thanks
