[FIX] Samsung Series 5 550 Chromebook, Linux Mint 18 / Ubuntu Xenial Not Refreshing Wireless Networks After Resume

After recently installing Linux Mint 18 on my Samsung Series 5 550 Chromebook, I noticed that after a system standby/resume, my wireless network list was not refreshing or connecting to networks if in a new location (for example, suspending the system at home, then resuming when at work it would not find new networks).

The following fix was found to work fine for me, credit goes to Ubuntu Forums here.

Apparently this is common for Broadcom wireless cards, mine however was a Atheros 93xx card:

rob@chromebook ~ $ lspci | grep -i wireless
01:00.0 Network controller: Qualcomm Atheros AR93xx Wireless Network Adapter (rev 01)

The fix was to create a new file:

sudo nano /etc/pm/sleep.d/10_restart-networkmanager

Paste the following into it:
#!/bin/sh
case "$1" in
resume|thaw)
service network-manager restart
;;
suspend|hibernate)
# Do nothing
;;
esac

Make sure root is the owner of the file:
sudo chown root /etc/pm/sleep.d/10_restart-networkmanager

And make the file executable:
sudo chmod +x /etc/pm/sleep.d/10_restart-networkmanager

Once done, reboot the laptop and you should then be able to suspend and resume the system without problems, upon resume, it will restart network-manager to work around the issue.
