Extreme WIFI Adapter

About: I like making films.

This instructable is going to teach you how to attach an antenna to a USB WIFI adapter.
Lets get started! 

Visit my blog for more stuff! : http://techreviewerblog.blogspot.com/

Step 1: Materials

You will need:
USB WIFI Adapter
Flat head screwdriver
External Antenna
Copper wire (about 1 mm)
Scissors and tape (or hot glue)

Tools (Not shown):
Drill
Hot Glue Gun

Step 2: Take the Thing Apart!

Using your flat head screwdriver, gently pry apart the USB WIFI stick.
Now look your circuit board. Mine had a single little rectangle antenna inside. This is what the antenna should be connected to.

Step 3: The Antenna...

Insert the copper wire into the small end of the antenna. Use hot glue to seal it.

Step 4: Make a Hole in the Case

Mark out a hole on the top where the little antenna inside is. Drill it out, and bend the little metal you connected to the antenna about 80 degrees. Then put it through the hole and make sure the wire and antenna make contact. Then glue everything shut.

Step 5: Testing

In testing before and after Windows showed the connection improved from "good" to "excellent".
The internet speed increased 10mbps! OMG!
In all this experiment was a complete success!
However in the future I would ground the antenna by soldering a wire from its ground to the ground on the USB port.

    Was happy to see people taking on DIY projects until this got near the end, then I was just shaking my head.

    Just "hot glueing" the cable in was one thing (without solder, you will likely lose a few db's of power just from that connection alone), but then the wire that comes out of the hot glue and goes to the adapter, what are you connecting it to? The big silver shield? That is a interference shield to protect the radio chip, that is NOT the antenna! That silver thing is actually grounded out.

    If you noticed any improvement from this, it was all in your head. But at least you dind't go soldering/removing stuff from the motherboard, so this mod likely didn't affect your performance.

    The antenna is actually on the motherboard itself, it is just a little bit of copper that could be imprinted in the circuit board and hard to 'see'.

    I thought a WI-Fi adapter was an antenna. What does your Wi-Fi adapter do? And where do you get one?

    And the cheapest ones you could get are probably from your nearest electronics store because you don't need to pay for shipping :D

    Its an adapter and antenna all in one package. I've gotten some nice antennas from dealextreme.com but you can almost make simple dipoles from short pieces of copper wire.

    On the ones I've hacked you have to remove a tiny surface mount jumper/capacitor to disable the internal antenna also.
