Here are the command outputs after a suspend/resume. This time I was
lucky and the wifi came back after restarting NetworkManager:

$ sudo systemctl restart NetworkManager
Wifi working again...
I'm also attaching a kern.log from the last hour. I noticed in there
that there was a Call Trace from the time when NetowrkManager would not
restart the network and I had to reboot. It's probably worth look at
that.

Title:
Can't connect to Wifi network after suspend and resume
Status in network-manager package in Ubuntu:
New
Bug description:
Beginning in Ubuntu 16.04 and getting worse after upgrading to 16.10,
I can't connect to wifi networks after suspending and resuming my
laptop. I have a Sony Vaio SVP112A1CL with wireless network controller
Intel Corporation Wireless 7260 (rev 6b).
Typically I have to restart NetworkManager to recover from the problem
(sudo systemctl restart NetworkManager). This seemed to be a reliable
way to recover in 16.04, but it doesn't always work in 16.10 and may
require a reboot.
In some related bug reports they requested we run `sudo iw dev wlan0
scan` which resulted initially in an error but after running it a few
times returned successfully. I'll attach the output below. Even though
it did return, the wifi network still was unable to reconnect. I'll
try to grab the errors next time, but if I do it now, I'll lose
connectivity.
