Build A Cheap Wi-Fi Signal Booster Out Of A Tin Can

Build A Cheap Wi-Fi Signal Booster Out Of A Tin Can

We’ve shown you how to build Wi-Fi signal boosters before, but if you’re lacking better materials you can always just use an old can. Here’s how.

What You’ll Need

– Two Milo tins or similar

– F-Type chassis mount

– Pig tale for F to Sma

– Short piece of copper wire

– Tin snips

– Can Opener

– Soldering Iron

– Drill

– Drill Bit

Using tin (foil) to amplify a signal has often been made a joke, but it does work if it meets certain standards. That’s the idea behind Instructables user budgethackdotcom‘s cantenna, and you can calculate how many cans you’re going to need with this cantenna calculator. While certainly not a complicated project, you’re not just throwing a can on your router. If you need to boost your signal and you’re comfortable with a little soldering, you should give it a shot. Be sure to hit up the full Instructables post for detailed instructions.

  • Much better way is to :

    Grab a rectangular, aluminium foil baking tray. Should be about 30cm long.

    Place it behind the wifi router, pressing on the side of the tray (now it’s base) to mold it into staying upright.

    This also weakens extended coverage/leakage (behind the tray) into neighbouring properties lessening any wardriving attempts.

    Can also create an ‘array’ with one tray behind the other, to enhance the signal.
