Hi guys!

I am new to Kali Linux forums, but was active at BackTrack forums.
A great period of time have passed when I stopped to deal with Linux and BackTrack, but now I have "little" problem.

I have installed Kali Linux to Virutal machine (VMware Workstation), and now I want to protect my router well. Namely, my neighbours have a bit more knowledge than me, so they are trying to steal my Wi-Fi.

So I started to deal with Reaver v1.4, and my router is downstairs. The power in dB is showing around 60-70. I am getting error something like this:
[!] Failed to associate with BSSID XX:XX:XX:XX:XX (essid: my_router_name)

Can you guys please help me? Yes, i have unlimited GB at my IP, but they are constantly slowing my surf speed down.

Thanks, I hope you guys can help!
