I am also having this problem on a Lenovo laptop running trusty (14.04.2 LTS) Now that the fix has been identified, will it be backported? What are the pros and cons of switching out the kernel?

Occasionally the indicator will show that the connection has been lost, but more often it seems that the indicator just shows low signal strength -- as it generally does even when the connection is working well. I'm pretty sure this is not an access-point problem because we have other devices using the same network without any problem. Here's some of the additional information that has been requested in other discussions of similar problems, although I don't fully understand what all these results mean.
