Hi, I Need Some Help with Reaver

First English is not my first language so I may have many mistakes writing ^^.

I read a lot in NullByte and also search Google but still no help with my problem so I think it's time to ask.

I have a router (I know its password of course) and my laptop is like 2 meters from it. I also have my friend's router next room, 5 meters from my laptop, both have WPS enabled. Signal is perfect.

Problem is when I run below command (which was success before for both routers)

reaver -i wlan0mon -b myroutermacaddress -c 2 -K -1 -vv

it shows:

! WARNING: Failed to associate with XX:XX:XX:XX:XX:XX (ESSID: (null))

! WARNING: Failed to associate with XX:XX:XX:XX:XX:XX (ESSID: (null))

... a lot of it

Sometime it does get associated, but rarely, only 1 or 2 times and then

! WARNING: Failed to associate with XX:XX:XX:XX:XX:XX (ESSID: (null))

! WARNING: Failed to associate with XX:XX:XX:XX:XX:XX (ESSID: (null))

...a lot of if again. It's stuck.

Both routers are not updated. But I did update my lap with

Apt-get update/upgrade/dist-upgrade (several times)

In short:

• I was success hacking both routers with the same command in the past, now I can't. The only thing get updated is my laptop.
• Signal is good
• WPS enabled and not locked
• I check my mac address, still the same, no changes
• My wireless card is good.
• I did have some line say that it's associated but then failed again.
• I tried with wifite, same problem.

Please suggest. Thank you very much!
