Szopin, most of the time I use -S and -a.

Honestly, I can't confirm deterioration - as written in my further (than quotation) posts, many times reaver was working quite fast, but wasn't able to find correct PIN even @ 100%, so it cycled from 0 again. I got NFC why it's like that.

From a month or so I'm unable to crack any new (not exactly bran new) WPS router I'm trying, and I have no idea if it's caused by firmware upgrades released by vendors after Reaver fuss, bad implementation or Reaver, or just bad luck.

Summing it up, I'll happily test latest version packaged into repos - it could be only better, I hope
