How to Increase Wi-Fi Signal

Sometimes, Wi-Fi signals are just to weak to be of use from your location, and purchasing an additional signal booster is costly, then you must read this post. A simple piece of cardboard, aluminum foil and glue can be turned into a very cheap and easy to make Wi-Fi signal booster.

The cheap homemade device is called Ez-12 Parabolic Reflector, or Windsurfer, and its really very easy to make and use. How? Watch this video:

Cool, huh?

Anyway, you can download the template here and just follow the instructions.

And here is the Windsurfer in action:

Thanks to Rabby C. for the photo. And if you are wondering if this really works, contact Rabby. His email is available upon request.

Note:

Rabby was kind enough to send his own testimonial about the Windsurfer:

Testimonial:

“This is a capture of the Windsurfer in action. FYI I am subscribed to SmartBro 384kbps, I went to my room to test if this thing actually works, (take note, my room has barely gets signal at all!) And as you can see from the picture as if I was standing beside the router with that kind of speed! Imagine I just made the small version of the Windsurfer, what more if I make one bigger?! This proves that the Windsurfer actually works! I will be constructing a bigger Windsurfer out of different kinds of materials and I will give feedback as soon as I have tested them. BTW Thank you Rai for posting this article” – Rabby C.

Thanks for the feedback, Rabby!

Hello, I recently made both the EZ-10 and EZ-12 antenna reflectors and tested them on my WPNT 834a RangeMax wireless router which has 3 broadcasting antennas and is a MIMO router. Today I woke up to having my DC transformer blown. And I am thinking it’s because these reflectors cause the router to suck more amps. Have you heard anything like this happening before? Luckily I have an universal tranformer I am using now to write here in this blog. Also, I have found that my EZ-12, which is 1.75x’s bigger than the original template doesn’t work as well as my 3 EZ-10s I have reduced by a 1/3 to fit on each antenna. For the Ez-10s I had to trim the left and right side of the outer antennas so they don’t interfere with the transmission from the middle antenna. Please if you have any input of why my transformer may have blown, if it’s possible that these reflectors cause my router to suck more amps I would like to know so I can just do without them and get another wifi router and use it as a repeater.

Hi i have just made the so called booster. It has not made any differents at all except i have just wasted my time in making one. If you want a sail make one if u want a booster for wifi dont bother with this.

Everyone!!! Please disregard my comment on Aug 24th …..I don’t know why my transformer wasn’t working that day but I switched back from my universal transformer to the original and voila! it works again ….I’m still scratching my head about it … The EZ-12 is still on my router ….I get close to 1/2 a bar to 1 bar boost…..I think I need to scale it down 1/3 like I did with the EZ-10s and use foil on the inside and outside (making sure the surface as smooth as possible …..) so far the router is close to 80 ft away from my Toshiba Laptop …it has a Atheros WiFi adapter much like my WPNT 834a router has …..that may be why I get a better connection at this distance compared to my roommates. …plus my laptop can probably outperform there more expensive laptops because they purchase good looking Sony’s and a HP but don’t know nothing about what’s better for performance …as long as it looks good though …??? I don’t get it myself ….. hehe

This looks like a great idea. I will have to build one and try it.

What if I don’t have a router? I am trying to boost the signal for my wii.

It works. i grow my connection from 95 to 98 in the main room
in bed room i grow from 60 to 89

just respect the size of A4 . Use material for reflection not for absorbe(many use wrong aluminum)

To the idiots claiming it doesn’t work, please explain the youtube videos of before and after demonstrations that PROVE it works on equipment that measures signals. You just have to use your head as to where to position it on the antenna, and where to direct it. I can guarantee you have failed because you simply don’t understand how a parabola works, or you were stupidly trying to make it send your crappy 802.11g a thousand feet or something. So everyone reading, please ignore the village idiots. This does work… and I was getting a very poor 32% signal on a PS3 in a bedroom, and I now get a usable 65%.
