Improve your WiFi signal with a reflector

wifiWhat do you do if your WiFi won’t quite reach to a bedroom at one end of the house? You have several options:

  1. Move your router closer to your bedroom.
  2. Buy a better wireless card for your laptop (one with an external antenna would give best results).
  3. Buy a wireless repeater and put it half way between your router and your bedroom.
  4. Add an external WiFi antenna to your router.
  5. Abandon WiFi and use a Cat5 cable.

All of the above options involve purchasing extra hardware and thus, extra cost. There is a much cheaper option if you’re on a budget… our free WiFi reflector!

How it works

Unless your router is in the middle of your house, much of it’s output power is being wasted. With a vertical antenna, the signal pattern is emitted in a circle (with the antenna at the centre). Typically, people put their routers near a wall (as that’s where the phone socket is) so up to half of the signal is going in the opposite direction to where it’s needed. A reflector will help focus that power in a more useful direction.

How to assemble the reflector

  1. Download our free WiFi reflector.
  2. Print onto some thin card.
  3. Glue a sheet of tinfoil onto the back of the card.
  4. Carefully cut out the design making sure you include the tabs on the centre piece, cut slits where shown in the main reflector and punch a hole for your antenna in the centre piece.
  5. Gently double over the centre piece and insert into the reflector.
  6. Slide the reflector onto your antenna and face towards the area which has a poor signal.
  7. Enjoy your improved signal!

Here’s one in position so you know what you’re aiming for:

Some routers have 2 antennas, just go ahead and make 2 reflectors and face them in an appropriate direction.

  1. Measured a single one and it appears to have about 8 Db gain front to back. Double one extended to two antennas side by side is a bit wider aperture and appears about the same gain. Will do some tests and see if it solves my friend’s low signal problem.

    1. Thanks for the report, Alan. I know they only provide a relatively small boost, but if you happen to be just on the edge of coverage, every db counts! Hope it helps your friend.

      This post hasn’t been updated in a while, I should really update the download with the current logo.
