  14e4:4331 [MacBookPro10,2] wifi intermittent Ubuntu 14.04

Status in “linux” package in Ubuntu:

Bug description:
  Problem: wifi is intermittent on my Macbook Pro and the logfile shows it's disconnecting
  Hardware System: Macbook Pro Retina 13" version 10,2 early 2013
  wifi firmware installed was default in Ubuntu 14.04 (mac 64bit OS) and synaptic shows the bcmwl-kernel-source to be installed. I get intermittent disconnections from the wifi which is set to g-only. Other wifi router settings have not been any better. Changing the wifi installation from the default of Ubuntu 14.04 have not improved things. I tried the firmware-b43-installer with similar results as above.
