I just noticed there is a new version of the Broadcom driver available
from their website: 6.30.223.248

I will try to build and test this driver tomorrow and report back. According to the changelog it might fix the problem:
"Upgraded to support 3.11.x."

Readme is here:
http://www.broadcom.com/docs/linux_sta/README_6.30.223.248.txt

If it fixes the problem, a backport would be great since this version of
the driver is currently not in 14.04 which uses kernel 3.13.

Title:
  Weak wifi signal and bluetooth missing firmware

Status in “bcmwl” package in Ubuntu:
  New

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).

  In addition, Bluetooth does not work because the driver reports
  missing firmware but there does not seem to be official firmware
  available anywhere.

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

  The 5 Ghz frequency seems to be not supported by the driver according
  to the README file and does not work at all. My router is set to use
  WPA2-PSK with AES, which is the only possible option besides WPA or
  WPA/WPA2-mixed.

  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".
