I'm completing the log report:
Which part of the process does the issue occur with, the suspend to ram, or
resuming from?
The network interface is not showing, thus no networks appear in the network
manager. Consequently, there is no internet.
Please advise how you suspended specifically. For example:
Shutting the lid of the laptop, which is set to suspend on close.
Please advise how you resumed specifically. For example:
Lifted the lid
I'm going to attach the log files in the next posts (the interface
allows one attachment and the instructions ask for not compressed files)

Title:
No network devices after suspend and resume
Status in linux package in Ubuntu:
Incomplete
Bug description:
I'm on an Alienware 17R3 on Ubuntu 16.04.
The wifi stops working after resume. The problem seems related to
https://bugs.launchpad.net/ubuntu/+source/wpa/+bug/1422143, but the
solutions proposed there doesn't work. Other seems to have a problem
related with the network-manager stop working (like
http://askubuntu.com/questions/761180/wifi-doesnt-work-after-suspend-
after-16-04-upgrade).
However, in my case the network-manager restarts and stops after the
resume. However, there is no device, and thus there is no list of
available networks to join.
For example, doing
$ iwconfig
lo no wireless extensions.
while in a normal reboot the wireless card information is printed
$ iwconfig
