Example of a USB Wifi Antenna

If you're tired of poor or intermittent wireless signals and can only detect one or two networks. and you want to connect to the cafe down the street, with very few skills and a couple of simple tools, you can build a powerful USB WiFi antenna that will boost your WiFi detection range tenfold or more.

Difficulty: Moderate

Instructions

Things You'll Need:

Tin can or other suitable metal object (a small pot or strainer will work too) USB WiFi adapter USB extender Cable

Step 1

Purchase a USB WiFi adapter from your local computer hardware store (The price should be around $40). Install it on your computer by following the on-screen set-up instructions.
Step 2

Find or buy an old metal object that is rounded such as a can or bowl, and cut a hole in it that allows the USB adapter to fit snugly within it.
Step 3

Push the USB adapter halfway through the hole so it won't slide out. Connect the USB extension cable from the computer to your adapter.
Step 4

Hang the "antenna" so that the adapter and antenna are facing out the window (towards wherever more signals are likely to be found).
Step 5

Search for and connect to wireless networks by right-clicking on the wireless icon in the taskbar and selecting "View Available Wireless Networks."
