I just installed Ubuntu on Lenovo laptop a week ago so I do not know if this problem existed before.
But I have another laptop, Toshiba. And I have never faced that problem on it. So it seems the problem is related to specific hardware. Let me know if you need to check the problem under prior Ubuntu release I will do it for you.
And I will check this problem with upstream kernel as you asked and say result today or tomorrow.

Bug description:
  Hello!
  My wifi works unstable. It means network goes down time to time. And it makes me crazy. I am not sure where to find a cause but I found strange errors in dmesg
