*** This bug is a duplicate of bug 1380480 ***

Not a duplicate of #1380480 as that bug report clearly states that
disabling and enabling networking in the applet restores the network.
This bug report clearly states that has been tried and does not work.
Note that since 16.04 I've been getting this on all computers that I
have and a lot more frequently. A separate bug has been raised for that
as it was a different operating system and affects different hardware.
See #1589125.

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):
Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI
Express Gigabit Ethernet Controller (rev 02)
Network controller: Qualcomm Atheros AR9287 Wireless Network Adapter
