[Bug 1312358] Re: wifi intermittent on Macbook Pro Retina 10, 2 Ubuntu 14.04

  Thread Previous • Date Previous • • Thread Next 
Phil Marsh, could you please post the results of the following terminal command:
iwconfig wlan0 | grep 'Power Management'

** Description changed:

  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
- My wifi is: Broadcom 4331
- The command lspci -nnk | grep -iA2 net shows the following:
- Network controller [0200]: Broadcom ....... [14e4:16a3] (rev 21) .......
- ...... Kernel driver in use: wl
+ 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.
