Scientists reveal simple hack that can improve your Wifi in minutes

[bathroommonkey76]

Scientists have revealed a simple trick that can improve your wireless signal and even strengthen its security, all for under $40 – and, it could outperform antennae that cost into the thousands.

The new technique relies on a 3D-printed reflector wrapped in aluminium foil, which directs the signals toward specific areas, and away from places they’re not needed.

While the device works best with the 3D printed material, as it can more accurately capture and maintain the optimal shape for the desired coverage, the team also says you can create a similar structure using cardboard.


The inexpensive technique developed by researchers at Dartmouth College and Columbia University essentially creates a ‘virtual wall’ to improve Wifi signal in indoor spaces with multiple rooms.

Shaping the signal allows users to funnel the Wifi toward the areas it’s most needed.

This, according to the team, can reduce interference and the signal-deadening effect of building materials, and even increase the system’s protection against cyberattacks by limiting the signal to certain spaces.

1. I have discovered a similar hack

For cutting cable TV bills

2. Going back to tin foil?

Who would have guessed?

3. I did this trick a few years ago

I found the template on the Internet, printed it out on cardboard, and wrapped it in aluminum foil. There was a noticeable improvement in our WiFi transmission, although I wouldn't call it "miraculous."

4. Some folks here may find this helpful, but the Mail and these scientists "discovered" old news!

I did this a few years ago using a template I downloaded and printed out onto card:



Just glue some foil on it, assemble, pierce a couple of holes for the antenna to fit through and you're good to go. It cost me vastly less than $40!



It significantly improved reception in our cranky house where we needed it, and means we're not broadcasting to the rest of the street.

There are other designs out there, but this is one of the simplest. Just Google Windsurfer wifi

5. Your cardboard and aluminum foil cost $40?

6. I know I'm just too old school but...

...$6 and change for Ethernet wins in my mind:
