it uses the ath9k driver:

Title:
Networking occasionally doesn't recover from suspend
Status in network-manager package in Ubuntu:
New
Bug description:
Occasionally, networking is disabled upon recovery from suspend.
Clicking "Enable Networking" on the menu from the notification icon
has no effect. It requires network-manager to be restarted with
`service network-manager restart`.
I can't identify a pattern to the problem. I can suspend the computer
for minutes or hours without it happening.
I've not noticed it on other computers running 14.04 that I have, so
it's probably limited to my this particular hardware.
I didn't notice it on previous versions of Ubuntu on this hardware.
However, due to the nature of the problem it will not be practical to
bisect the kernel as I don't have a reliable method of reproducing the
fault as of yet.
My network devices are as follows (I use the wireless one only):
