Comment 73 for bug 1260825

I have the same problem with my Lenovo M30-70 with a Atheros WB335-card.

xxx@xxx:~$ uname -a
Linux xxx 3.18.2-031802-generic #201501082011 SMP Thu Jan 8 20:13:03 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

xxx@xxx:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04.1 LTS
Release: 14.04
Codename: trusty

Sometimes it works, but most of the time it doesn't.

This is when it DOESN'T work:
