Wireless issue WPS handhake in kali linux
 

I try to make WPA handshake with a wifi network , sometimes the handshake goes smoothly,but sometimes it doesnt make handshake.could you suggest best comment?

Hey Sam. I don't think you realize this but you are not supposed to just tittle your posts 'help me'.
There isn't an awful lot of pleasant chit chat around here, it's all pretty much 'help me'.
What helps the people who want to help you is if you take a moment and tell us what the problem you're facing is in the title.
That way, if we are knowledgeable about that area of your operating system, we can open the post and take a moment to see if we can help you.

So, a good title for this post might be...

Wireless issue: WPA handshake intermittent failure <Linux Distribution> <Version>

In regards to your question I don't know, I don't do wireless.
Or Apple.
That's why you should put that information in the title, it saves both of us time.

Just a suggestion, but I'd see if it wrote a log file somewhere when it fails.

okay i will
