Wifi Signal Strainer (WokFi) Long Distance





Introduction: Wifi Signal Strainer (WokFi) Long Distance

In this instructable I make a common WiFi Thumbdrive into a beefy wifi extender!'

The parabolic Asian cooking(dumpling) strainer is the perfect candidate for this project.

I was able to pick up 20 more access points in the city and connect to a network a few blocks away!

This is BY-FAR the most simple of all Wifi extensions!

_best paint'job EVER!_ - This is the general Idea behind the parabolic dish.
- it should bounce all waves from the dish into the focalpoint (wifi thumbstick).

Step 1: GO GET STUFF!!!

OK, you have to get :

a) Cooking strainer from Asian food market.
- Needs to be PARABOLIC
-The wooden handle on mine made it easy to work with.
-Cost $7.00
-Mesh should be similar "tightness" as pictured. (Don't get the loose mesh)

b)USB Wireless Thumb Drive (g or b/g)

c) USB extension. -- The longer the better.(but get as much as you need.)

Step 2: Prep and Build the Signal Strainer!

Image 1:
-Using the snips and cup out a hole JUST big enough for the USB extension cord.

Image 2:
Squeeze the tip of the USB cord through hole.

Image 3:
-Adjust everything so the thumbdrive is at the FOCAL POINT of the parabola (I just eyeballed it).
-Fasten the USB cord in to place.

Step 3: Testing the Signal Strainer

Testing the Signal Strainer:

1) Find your favorite access point!
2) get as far away as possible! (While keeping line-of-sight)
3) Use software like NetStumbler to see the signal strength.
4)Adjust your Signal Strainer where necessary.

    Combine this with Aircrack, and you get free unlimited wifi!

    Haha, yes. Very illegal. But fun!

    it isn't illegal if you don't get caught

    And it isn't illegal in the first place too!

    Show me the law that states that connecting to unsecured networks are illegal...

    Im in texas,


    in Texas, the statute is Penal Code section 33.02, Breach of Computer Security. It says, “A person commits an offense if the person knowingly accesses a computer, computer network or computer system without the effective consent of the owner
