[TIP] Wake On Lan
Here is a tip for anyone looking to use their phone to wake up their computer. There's a few ways to do this, but I will explain my way.
What you'll need is a rooted phone, and busybox (with ether-wake compiled in).
Basically, you just run the shell command:
ether-wake -b -i wlan0 XX:XX:XX:XX:XX:XX
Replace the "XX:XX:XX:XX:XX:XX" with the MAC Address of the computer you want to wake.
Example: ether-wake -b -i wlan0 12:34:56:78:90:AB
Now why use this and not the many Wake On Lan apps from the Play Store? Well, this is a simple command line that can be used in Tasker via the shell run command option. And you don't need to install an app, and you don't need to navigate through an app every time you want to wake your computer.
Real world use:
I hover my phone over an NFC tag, and my laptop wakes up. I used NFC Task Launcher to write a task to an NFC Tag (NTAG203). The NFC Task Launcher launches the Tasker task that runs the shell command above.
