Hi Chris and team at Ubuntu,
Thanks so much for helping me solve this. I'm amazed at the quick and
professional response from you and the rest of the team. Try to get this
level of support from Microsoft!
So far, after about 5hrs of VNC/VPN connectivity through wifi on my
MacBook, it appears rock solid! Hoping that someday it will run an n
protocol wifi connection but I'm running g for now and quite happy.
I think it's solved, but will let you know if another issue appears and I
can't solve it.
I'm very pleased so far with Ubuntu 14.04. Love the Macbook hardware but
wanted to run Ubuntu, which I know.
Thanks again,
Phil

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

Status in “linux” package in Ubuntu:
  Confirmed

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.

  iwconfig wlan0 | grep 'Power Management'
  Power Management:off

  WORKAROUND: Turn WiFi Power Management on.
