I’ve been using a wireless Ethernet card in my laptop. But now the change from wired networking to wireless was an amazing shift. Now I could wander around my office or my home and connect to the Web. However, in many situations, I found that the range of the built-in antenna in the PC card was limited, and I desired additional range.
In this tweak I will show you two different and inexpensive ways to increase your laptops wireless LAN card antennas range. In this method we use old coffee can to make our new antenna. With this method we can send and receive data in one direction upto 16 times more powerful than built in antenna in your wireless card. And in another method we will use satellite dish TV antenna. It is highly directional and can send and receive data upto 10 kilometers to another disk in ideal conditions. Here below is Hack 1 - Increase wireless using coffee can.
In this hack you can use 802.11 network card of any brand. You will need 'pigtail' connector to connect wireless card on one hand and 'N' connector on another hand.

Enjoy!

In this hack you can use 802.11 network card of any brand. You will need 'pigtail' connector to connect wireless card on one hand and 'N' connector on another hand.
You will Need:
- A metal can : 3 - 3.5 inches diameter and 4 inches long (Metal soup can works well)
- 4-40 type screw and nuts : Quantity 4
- 12 Gauge copper wire : 4 inches
- N style RF connector
- A pigtail connector that has the proprietary Lucent connector on one end and an N connector on the other
- Low loss coaxial cable : 30 - 60 feet
- Soldering Iron

| Drill holes as above |
Process:
1. Take any can that has 3-3.5 inches diameter and equal to or longer than 4 inches and make sure that it's dry and clean and it's open end is free from ragged metal edges.
2. Now drill a hole from approx. 2.5 inches from closed end of the can for N connector.
3. Now take an N connector and add a short piece of 12 gauge wire such that wire sticks up 1.25 inches from can walls.Now mount the N connector in the can where you have drilled a hole.

| N Connector |
4. Now open your wireless card and remove cap and connect that pigtail or don't want this pigtail step than open your card and solder a wire to the antenna inside.
5. Now connect soldered wire which is connected to antenna and 12 gauge wire which is connected with N connector. Now you have your wireless card connected with metal can. This metal can works as powerful antenna.

Now start your laptop and aim open end of the can towards wireless access point or wireless enabled computer. Now note down signal strength and then remove antenna now again measure signal strength. You may see difference because when we attach antenna signal is polarizes in one direction.
WARNING:
Never look into the open end of your antenna when it is operating. Your antenna focuses the signal to levels that could be harmful.
Enjoy!
