How to Have Internet When There Is No Power.
Intro: How to Have Internet When There Is No Power.
If you live in the area I do, power outages can be a bit common due to storms and such. Being the person I am, the internet would be so nice during that power outage,
So one outage I observed some stuff and noticed, I can have internet when there is no power.
Read on if you are intrigued.

STEP 1: Observe!
Before we start, we need to know what we have and what we don't.
-Check your phone, is the line dead? If its not, you're good.
-Check to make sure your ethernet router takes the phone cord in.
-Make sure you have a laptop with a charged battery.
If you have a "2Wire" brand router, it should take in 5V.
Basics done, check some technical stuff!
Check your router, make sure it takes in 5V for power. If it is not written on the router you should be able to see it on the power supply for the router.
Check to make sure you have the right plug to fit the power jack on your router. Don't cut the original power cable, since you'll need it once the power is back on.
Now, on to the next step!

STEP 2: Make Special Power Cords
If you've moved on to this step, I'm assuming you have a router that runs on 5V.
Now, you will need a plug that fits your router's power jack, and a USB cord.
Cut off the peripheral end of the USB cord so you are left with the part that plugs into your laptop.
Strip the wires on the jack and the USB cord, and connect the red wires and black wires, if the wires in the power jack cord are a different set of colors, match red to one of the wires and black to the other, then move on.

STEP 3: Turn It On!
First, connect the ethernet cord if your laptop connects to the router in that fashion.
Next, plug the power cord you just made into the laptop and the router.
Turn on your laptop. Check the router for signs of power.
If it shows it has power, then great! You have internet for as long as your laptop battery lasts.
But if it doesn't, consider the following:
-Try swapping the red and black wires from the USB cord and test again.
-If nothing gets it to work, your router might use too much current for the USB port to supply (shouldn't be a problem, my router pulls 2A but used the 500mA just fine.) or your router might run on a higher voltage than 5V. Double check the router and the router power supply for the voltages.
If you got your internet working, I hope you enjoyed my Instructable.
Just remember; I am in no way responsible for any damage inflicted to your equipment should you choose to follow these instructions.

Um: "Try swapping the red and black wires from the USB cord and test again.". That's just bad advice. How about showing actual pinouts so you can get it right the first time?

USB is DC, your router uses AC. Even if you get the wires hooked up correctly, you're going to fry those capacitors. There's a reason why he wrote "I am in no way responsible for any damage inflicted to your equipment."

Lol this modem like all the others uses DC input.
AC->DC is made through the bloc on the plug.

just a quick note. just because you can power your router/modem, doesn't mean that your ISP will power your Internet.
for me Comcast Cable didn't, but frontier DSL did. ( however I have also heard the opposite, so it is regional/VOIP dependent. ) Hughes–net did, however it was usually during a storm which would knock out service anyway.
we are now over with AT&T cellular, they do; although it is quite possible to hit a tower that Isn't ( it was quite nice during hurricane Sandy, which was during our transition from that other HN company).

I have a question.
Is there a way to not only have a U.P.S.(uninterruptible power source/supply), but also have a fully charged battery for your lappy?
I guess what I'm asking is there a cord, or something, so you can play on the internet(when the power is on) & be charging 2 batteries at the same time?
My thinking is that with this set up, you would have 3 power sources when the power gets knocked out due to a storm, or someone's stupidity(drinking & driving, falling asleep at the wheel, etc)...

Sweet Jesus!
now why didn't I think of that?
That is such a cool idea!!
TY for sharing! :)

the "greener" the router the longer it would last.
that would be something to test though.

and im pretty sure its against most laws to leech the power from phone lines too.

Correct me if I am wrong, but you connect the ports in parallel you increase the amps, whilst in series the voltage is increased.

Parallel is dubious, but may work ...
If you really need more than 5v you will need a DC-DC converter, or an external battery. Not multiple USB ports, sadly.
zack247 12 years ago
usb ports all have the same ground and 5v planes, connecting the 5v of one port to the GND of the next will just short out the power supply, and shut off your laptop.
it was a good idea, but unfortunately it cant work that way.

One connector is dedicated 5v/GND whilst the other is 5v/GND/Data.
