I was going to submit a new bug with my Carbon X3, but it says linux-image-3.19.0-12-generic is not an official package. I'll try again after a reboot with the new kernel.
Anyway, my symptoms differ. I can get it back with a disable/re-enable. I've noticed download speeds seem to vary dramatically, sometimes connection to a website is lost and regained causing the page to timeout temporarily, etc. This started to occur after I upgraded to 15.04. It did not occur previously. I did this to get all the mouse buttons working properly, which they do, but something between the two really messed with wireless dependability.
