Is Reaver Dead?

Is the Wi-Fi key cracker dead or still breathing?

Because in my experience which is a bit premature and is only based on testing on 3 laptops and 2 kali distros namely Kali 1 and Kali SANA, Reaver hasn't worked for me. It used to do its charm till the mid of last year i.e. 2015 but with the advent of new routers that come with improved technology and lock-out defenders, reaver remains at bay now. It gets interesting when you test it against the same old routers that you once used to employ it against and get the password within 4-5 hours of cracking but now surprisingly it doesn't work against them either. I have tested it against two such routers. It is giving results against one of them but only on the previous old Kali distro not on the Sana one. While no results at all against another router on both distros. I'm attaching a screencap as a piece of evidence to prove my point.

What exactly is happening? Why is reaver being cornered and why haven't they done anything to make it better or immune to the lock-out plague?

If you try reaver now, it is extremely arduous to get it associated with the AP in the first place. It takes around 5 minutes to associate with the targeted AP and once connected, it makes a few PIN attempts and then again displays the same 'Unable to Associate' message.

If you somehow get through that phase unhurt, there's a very high probability of you receiving the "Retrying previous PIN" message which seems to stay there no matter whatever code and command magic you cast.

If you have managed to bypass that as well, then comes the ultimate weapon called the lock-out technology against which reaver is clueless. So it stops the process and sits there like a defeated warrior with a message "AP rate limiting, cracking shalt be resumed after __ seconds depending upon the delay time you have set". I have tried setting the delay time to even 10 minutes only to receive the same message again.

Can someone shed some light on what's going on here and why haven't they done anything to save the one router PIN cracker there is?

Also, what other options do we have down our sleeves to hack a wifi network besides dictionary, wifiphisher and evil twin method?

Thankyou :')
