Turbo Boost your WiFi Signal in 15 mins – with a bit of foil and a DIY template


Suffering from low signal in your WiFi network because of too many walls in the way or whatever? Try this quick and dirty DIY WiFi Antenna hack, which apparently significantly boosts your signal on the cheap (i.e. no repeaters needed). There’s a little confusion over whether the foil goes on the back or the front of the antenna, but that’s easy enough to test right? Useful. More here. [Via]

 # Download Template # Open in MS Paint and resize as desired. Ensure that you keep the square on the diagram square. # Print image on business card stock or acetate (document protector). # Cut it out and open the six slots with sissors or an X-Acto knife. # Glue tin foil to the back side of the reflector surface # Assemble by placing the six tabs in the six slots.


  • It works, though it doesn't make a vast difference. I used to live in a long, narrow apartment and made one to focus the WiFi in a single direction since the router had to be in the room at the very end. Managed to extend coverage by an extra room, which was just what was needed.

    I put the foil on the inside, IIRC.

    • Hmm…one room is pretty good, Chris I reckon. And the price has gotta be unbeatable. :)
