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!
-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
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!
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.
