There is a patch for the driver on http://pastebin.com/pATazP6K – found
it through https://aur.archlinux.org/packages/broadcom-wl/

I've applied the patch on my Lenovo Z510 (which also has a BCM43142
chip) using dkms (copied the patch into /usr/src/bcmwl-…/patches, edited
the dkms.conf, adding the patch name, called dkms common-postinstall)
and since then the wifi has been rock solid.

@Christopher M. Penalver: Can I somehow help to include the patch in the
bcmwl-kernel-source package?

Title:
  14e4:4365 Weak wifi signal

Status in bcmwl package in Ubuntu:
  Incomplete

Bug description:
  On a fresh install of Ubuntu 14.04 on my new HP Pavilion 15-020ng with
  Broadcom BCM43142 hybrid wifi/bluetooth chipset the official driver
  from Broadcom does not work correctly. On 2.4 GHz the wifi signal is
  so low that the connection is interrupted on a regular basis (network
  manager shows 26 Mb/s), other devices (notebook, tablet) do have a
  normal signal at the same position and even this laptop has a good
  signal with Windows 7 (Dual-Boot).

  The exact device name:
  08:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

  I am using the official wl driver that was installed by default, also
  tried reinstalling via "sudo apt-get install bcmwl-kernel-source
  --reinstall" without improvement and "sudo iwconfig wlan0 power off".
  Also blacklisted b43, brcmsmac and bcma as suggested by "Linux
  Wireless".
