Homemade Wi-Fi Extender

By Marshal M. Rosenthal

A Wi-Fi extender’s purpose is to intensify the Wi-Fi signals around a Wi-Fi antenna. A homemade Wi-Fi extender can be built from a few items commonly found around the home. The procedure is straightforward and does not require any special electronics skills. The Wi-Fi antenna that will be using the Wi-Fi extender will not need to be modified in any way. Adult supervision is suggested if the person making the Wi-Fi extender is underage since a cutting edge must be used.

Things You'll Need

  • Wireless home network
  • Soup can
  • Plastic storage container
  • Can opener
  • Dishwashing liquid
  • Paper towel
  • Scissors
  • Duct tape
  • Ruler
  • Grease pencil

Step 1

Open the can of soup with a can opener. Pour the soup into a plastic storage container. Wash out the can with dishwashing liquid and tap water from the kitchen sink. Wipe out the can with a paper towel.

Step 2

Place strips of duct tape around the open rim of the can. Smooth the duct tape down with your fingers.

Step 3

Stand the can on a table. Measure up four inches from the bottom of the can. Make a dot at the four inch mark with the grease pencil. Place the can on its side with the grease pencil mark facing up.

Step 4

Push the blades of the scissors through the grease pencil mark. Rotate the blades of the scissors to enlarge the hole just made. Stop rotating the blades of the scissors when the hole is a bit more than twice as big as when it was first made.

Step 5

Place the antenna of the wireless device into the hole in your homemade Wi-Fi extender. Aim the open end of your Wi-Fi extender in the direction of the Wi-Fi transmitter of your wireless home network.

Tips & Warnings

  • Cell phones can interfere with the Wi-Fi signal if they are placed too close to a Wi-Fi antenna.
