Today's geek recipe is one of those nerdily awesomelicious things you can do with your Android phone that you probably never even thought you could - imagine coming home and having your computer turn on the moment your phone connects to the Wi-Fi network. My computer is on 24/7 in case I need to connect to it remotely, but for those who turn their PCs off in the morning and on after work, this tip could be right on the money.

There are 2 options you could go with - both use the WOL (wake-on-LAN) capabilities most modern computers should have baked in (though you may need to enable them in the BIOS and power management settings of your network card).

1. PcAutoWaker

PcAutoWaker is a free app that does the job for you. Just install it, add up to 5 PCs into the app, configure which Wi-Fi access point it should consider a trigger, and voila - you're done. You can even test whether the app works by sending a wake-up command to all computers on the network at the same time. Neat.

Note: The app's description is in very broken English as the developer seems to be Japanese. Don't mind that - PcAutoWaker has a 4.4-star average score with over 50 ratings so far, so it most definitely works.


2. Using Tasker

If apps with poorly translated interfaces are not your cup of tea and you own Tasker, one of the greatest app to ever grace Android with its presence, another solution exists, involving Tasker and a different free app.

Enter Wol Wake on Lan Wan (a name full of keywords - very original), which does the heavy lifting of WOL for you, automated using a relatively simple Tasker script. The details of the whole setup can be found here.

So, are you going to take the red pill or a blue pill (or is there a purple pill that offers a completely different solution that we haven't mentioned)?

Edit: The question is, what happens if your Wi-Fi drops off, and your phone reconnects? I hope there is some safeguard built into the apps, but I have my doubts. If not, there should be.

    Very nice. I keep my home PC on all the time. But I wonder if there are other fun applications that could be done with this.

  • John Smith

    It does not turn your PC on. It wakes it. Nothing special at all. My old IT department could do this.

      1. Yes, full power-on. Look into how WOL works, so unless your computer is unplugged from the WOL (ha, I mean wall) and it supports WOL, it should wake up from being fully off.

      2. I don't think you really get the point here. So your IT could do this... so?

      • Aaron Gingrich

        Yeah dude, my IT department at home can do this too. I think you need to consider firing yours if they can't.

          "My IT department at home..."

          -- what is this I don't even.... ? O_O

        word of caution about WOL make sure your computer has a UPS as if power gets interrupted like a blackout the magic that is WOL will not work and you will need to manually boot the computer always a pain if the computer is not easily accessible etc.

    I use the purple pill. A PC running Ubuntu that boots in ~10 seconds from when I click the power button. Just enough time to have a piss. :)

    WOL doesnt work right with wifi. Yea if you are plugged in WOL works great cause the nic is never off. But WIFI the power to the wifi card is off when the computer is sleeping...dumb concept.

    • http://www.AndroidPolice.com Artem Russakovskii

      While there is a way to do Wi-Fi WOL, it probably won't work in this scenario, so you'd have to be on a wired LAN.

      Most desktops are connected using wired LAN and some laptop workstations, especially ones with docks, but you're right - this won't and can't work for everyone.

      Still, calling it a dumb concept is the same as calling WOL a dumb concept, which clearly isn't.

    Artem the app clearly has useful advantages. I never understand why people will post the first negative thing that pops in the brain, without even considering all of the interesting uses for this app. Thanks for the heads up.

      Trolls be trolling and stirring up the drama pot. The internets will never change.

    This is super cool! Thank you Android Police! ^^

    I had tested quite some time back, worked like a breeze. But I wanted to "Remotely" wake up my computer, for which I wasn't able to get the latest IP address of my Wi-Fi router. Tried many ways, but finally came to know I'll have to open up few ports (and reduce security)... so chucked the plan!

    Do you have any idea for doing that w/o opening the port and compromising my laptops security?

  • TBolt

    I recently installed PC Monitor on my DInc. Was happy to find that I could wake my PC with it -- haven't tested it away from my network yet, though.
