dmesg log gets filled with the info below. After a random time (sometimes minutes, sometimes hours), I lose wifi connection and the only solution I know is to reboot. It only started happening a week ago. I have been running kernel 3.13.0-34-generic but downgraded to 3.13.0-27-generic and that seems to have slightly reduced the frequency of the issue but I'm not sure.
