Further update,

The issue remains, I didn't notice it because in Arch linux the driver
had better performance and from my AP distance I was kinda OK, however
when I have moved for a few metters the signal drops to ~55% and the
issue persisted in kernel 4.2.

It is driver issue though

Title:
  BCM43142 will stop working when signal is below 55%

Status in bcmwl package in Ubuntu:
  Confirmed

Bug description:
  Lenovo ThinkPad E545

  Network controller : Broadcom Corporation BCM43142 802.11b/g/n (rev
  01)

  If you are using this WIFI card, beware that *bcmwf-kernel-source* does perform very badly with a newer version
  of the *bcmwf-kernel-source* 6.30.223.248-bdcom-0ubuntuXX (XX I have tried them all and all are not working)

  Desripction of what is happening:

  You are connnected to a network (does not matter on the router config
  or router) and when you are at signal level cca 55% and less the
  internet drops and you are offline (still connected but no packets get
  in or out) for a long period of time (restarting card works for a few
  moments when the drop occurs again)

  *bcmwf-kernel-source* 6.30.223.141 works as it should, but I am stuck
  in kernel 3.13 as I want to go kernel 3.19 and I can't because I have
  to use newer bcmwf and it is unstable, very much.
