Public bug reported:
I have a fresh install of 14.04 lts on a Lenovo X1 Carbon v2. I've
noticed that the wireless network connection will drop and I have to
disable and reenable networking to get it to work again.
It's occurring to me now that this could be a problem with
NetowrkManager rather than the kernel.
Please let me know how I can help debug. Thanks!
