Disable Sleep/Suspend and WiFi in Ubuntu 16.04 LTS
Raw
disable-suspend.md

On Ubuntu 16.04 LTS, I successfully used the following to disable suspend:

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

And this to re-enable it:

sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target

Raw
disable-wifi.md

The command-line equivalent in ubuntu 16.04 to disable WiFi

nmcli radio wifi off

To re-enable, use

nmcli radio wifi on

To help

nmcli radio help nmcli radio wifi help

Regarding disable-suspend.md:

Masking all these targets can have side effects, such as dbus-daemon getting stuck in a loop trying to trigger the suspend target (causing a high CPU load).

A better approach is to configure the system to not go to sleep when it's idle, and to ignore ACPI events which would normally trigger sleep / suspend. logind.conf(5) discusses the following options - which could be set in e.g. /etc/systemd/logind.conf.d/ignore-acpi-events.conf:

IdleAction=
HandlePowerKey=
HandleSuspendKey=
HandleHibernateKey=
HandleLidSwitch=
HandleLidSwitchDocked=
