I had used: sudo iwconfig wlan0 power on to turn on power management on my MacBook Pro Retina 13" laptop (Ubuntu 14.04) and the intermittent wifi problem appears to have gone away. The intermittent wifi problem was especially noticable due to my connecting my machines via vnc and telnet tunneled through an OpenVPN virtual LAN. When the wifi was intermittent, the telnet would hang at login (even when the wifi connection seemed to be otherwise working) and also the VNC connection would eventually stop, leaving a frozen VNC window on the client connecting to the MacBook Pro. The VNC connection would not recover, even if the wifi connection recovered. Therefore, both the telnet and VNC connections appeared to be sensitive measures of wifi connectivity. Since turning on the wifi power management, telnet and VNC appear to be stable! I did not yet experiment further to verify that the power management setting was truelly correlated to the intermittent wifi behavior but that is something I'll likely try soon. I will need to make the power management on permanent and I think instructions to do so are on the Web. Thanks, Phil
