I don't think it is a kernel bug anymore because I tested it on mainline kernel versions 4.2.0 4.1.14 3.18.3 and it did not worked on any of the above, all of them were mainline kernels.
But I'm sure my Wi-fi worked properly on previous versions of ubuntu that I've used i.e 14.10,15.04,15.10 and also in the starting of 16.04 LTS. I don't know what to do now.
