How to make a wi-fi signal amplifier yourself? Several ways

There are many different reasons, because of which the tablet or laptop does not catch the signal of the wi-fi. Quite possibly, the reason lies in the notebook itself, in which a weak antenna is used, which does not allow to use the Internet in full force, but most often the problem lies in the router itself. It's easy to check, because if the phone, and the tablet, and the laptop in the house do not catch the signal well, the whole problem is in the transmitting device. And in general, cheap routers with weak antennas often can not "break through" the concrete wall. In this case, the weak signal sometimes does not make sense. To fix the situation, you need a wi-fi amplifier. You can do it yourself.

Ready-made wi-fi signal amplifiers

At least there are several ways to make the signal of the wi-fi stronger. The simplest option is to buy a ready amplifier. Such a device can transmit a signal through reinforced concrete structures and for a distance of up to 200 meters. In the open space, such amplifiers transmit a signal for 2 kilometers. In addition, such devices can receive signals at great distances. Having installed this at home (on the roof), you can catch up to twenty networks, and some of them can generally be without passwords. As a result of the Wi-Fi, the signal amplifier will allow you to connect to the free Internet. A similar topic is being actively discussed. And indeed, some users, who do not have enough Wi-Fi even to the door, remove the password and make their network available for such receivers.

Create a wi-fi signal amplifier with our own hands

There are many crafts, which independently created amplifiers. Let's look at the most common and working options. You can make such amplifiers of the wi-fi signal with your own hands in just 10 minutes from improvised materials.

The very first and simplest option is to use a disc box. It has the ideal radius for our purpose. So, take the CD BOX and cut off the spire, but not completely. It is necessary to leave about 18 mm. Now, with a file on the spire, we make small cuttings for fastening.

The next stage is the creation of copper squares. We are looking for a wire of 25 centimeters long and making two squares out of it by bending the ends. These copper structures are analogue to the antenna, fix them on the spire of our disc box and glue.

The ends of the antenna must be soldered together and soldered to the coaxial cable that leads to our modem. At the bottom of this installation, put the CD-ROM, which will be here as a reflector.

Connecting the amplifier

Now, when the amplifier we already have, it must be properly connected. To do this, remove the cover of our router and look for a PCMCIA card with an antenna. Ideally, the old antenna should be repaired, and the new one should be soldered. Only it is worth considering that when soldering at high temperature, some thin wiring can come unstuck from the board. However, the antenna can also be connected via the SMA connector, to which the old antenna is connected.

Done, now you can test all the power of the newly created wi-fi amplifier.

Amplifier from the beer can

In this case, it will not be so much about the amplifier as about the reflector of the signal. The principle of the following construction is based on concentrating the signal of reception / transmission in a specific direction. That is, to get a stronger signal, the antenna will need to be sent to the place where the wi-fi signal is weak.

So, to begin with, find the iron jar of any volume, cut off the bottom and almost completely the top. But do not cut the upper part to the end, leave a small fixation from the side of the hole. This hole will include the antenna of the router.

So we get a cylinder that needs to be cut along, just opposite the hole in the top of the can. So we have a smooth oval surface that perfectly reflects the waves. Put all this construction on the antenna of the router and turn it to the side where you need to amplify the signal wi-fi.

It is worth noting that the effectiveness of this method is somewhat lower compared to the previous one. In this case, we do not amplify the signal in any way, but only concentrate it in one direction. Most likely, in other places of the room it will become weaker.

Which option is better?

If you do not know the skills in radio electronics and do not know how to solder and what to plug into the chips, the idea of creating an antenna for the router is not good. At a minimum, you can make an amplifier with a beer can. It will work, but expect high efficiency of such a device is not worth it.

The second option is to buy a ready-made Wi-Fi amplifier for a laptop, which is sold in electronics stores. Such devices are also quite a lot on Aliexpress, where they are not so expensive. In addition, you can derive additional benefits from the purchase of such equipment. Considering the power of such an amplifier of a wi-fi signal, it can be used to catch many other networks, including networks with no password.

Software Methods

In some forums, the possibility of creating software amplifiers of a wi-fi signal by oneself is discussed. True, the effectiveness of such a method can be safely questioned. After all, if the antenna on the router is weak, then no firmware or program installed on the computer can significantly amplify the signal. It is possible, with the help of a new firmware, you can achieve a stronger signal, but the difference will be insignificant.

Conclusion

On this issue of creating a wi-fi amplifier with their own hands can be considered exhausted. Of course, there are many other artisanal amps like cans for beer, but they differ little from each other.
