Public bug reported:
Hi,
After a few minutes, some times an hour or two, wireless stop working,
some times it doesnt stop but starts dropping most packages which ends
with laptop unable to open a single socket.
I've installed a fresh install of Ubuntu 14.04 LTS.
beep@t440s:~$ lsb_release -rd
Description: Ubuntu 14.04.1 LTS
Release: 14.04

What I expect to happen?
If I connect to a wireless network and the AP works fine, keep connected to
that wireless network and being able to send and receive packets between the AP
and the computer.
What happened instead?
After a few minutes or some times hours, some times start dropping packets,
sometimes it doesnt work at all.
