Wifi adapter next to the antenna. How to make an inexpensive WiFi antenna. Wireless connection speed

Please note that some software may be presented in the form of demo versions and have shareware distribution.

Finally, let's make a retreat. One of our customers, having familiarized himself with our device, was very surprised by its possible use and wrote to us - you have made equipment for WiFi theft!

Of course, an attacker can use the “WiFi Agent” for illegal purposes. But, with the same success, one can blame the ax sellers for the fact that the new “Raskolnikov” will buy an ax and attack the old money-lender. And dishware sellers are generally accomplices of criminals. There are knives, rolling pins, and a terrible weapon - a cast-iron frying pan.

In light of recent laws, it should be noted that our device does not contain any cryptographic encryption means and is not WiFi router. The “WiFi Agent” USB WiFi adapter with a directional antenna does not use any means to hack other people’s networks and does not make the process of “theft” one iota easier than a standard laptop WiFi adapter.

We believe that the issue of using any devices within the framework of the law is the direct responsibility of the consumer. Therefore, of course, when performing any action, it is always necessary to remember the legal side of the issue.

We recommend using "WiFi Agent" in situations where the standard WiFi adapter of your laptop or PC receives a low-level WiFi network signal, as well as in cases when you need to use your own WiFi network, being at a great distance from the router.

Hello friends. The other day I received this thing called a Wi-Fi USB antenna. Here in a box like this. In a nutshell, this is the same USB Wi-Fi adapter for a computer, only with a directional antenna and wire.

Description.

But compared to a regular USB Wi-Fi module or adapter, this device has significantly increased transmitter power and receiver sensitivity. Plus, the device has an outdoor design and is intended primarily for use outdoors, in an outdoor environment, and can easily withstand our frosts, as it has a wide operating temperature range and a sealed, corrosion-resistant housing.
Comes with a bracket for mounting on a wall or other support. The joint is glued with silicone for tightness. The antenna has a 5 meter long wire with a USB plug. The antenna is powered by USB and does not require additional power.
According to the manufacturer, the antenna can have a range of up to 3 kilometers. But again, this means communication between devices of the same type at a distance without barriers. It may well be that I did not have the opportunity to check. I was pleased with the results I received in the work. And I can confidently assure you that the purchase will definitely not disappoint you.

Installation.

The Wi-Fi USB antenna comes with a disk with drivers and programs. I personally didn’t even open it: I connected the antenna to the computer and netbook, and everywhere the system itself found the driver, the systems were also different. On a computer there is a ten, and not on a netbook - a seven. Moreover, no incidents occurred due to the built-in Wi-Fi modules. Naturally, if for some reason you have problems installing the software, take the disk and install it. Wi-Fi USB antenna is compatible with all Windows 7/Windows XP/Vista operating systems.
I will show you the work using the example of a netbook. The built-in one is working now Wi-Fi module and defines about 3-4 networks. We connect our remote antenna. We see that despite the fact that the antennas are located together, this antenna catches an order of magnitude more networks, and even with a better signal, this can be seen by the number of stripes on the reception icon.
And if you take the antenna out into the street, and onto a hill, then I feel you will have the entire area under control.
Our town is not big, so Wi-Fi points once or twice and got it wrong. When I went to St. Petersburg and took the antenna with me, the difference in the number of networks was exactly ten times! In the hotel where I lived, regular Wi-Fi caught 7-8 networks, and I counted 65 with the antenna. I think the result of the work is decent.
The antenna operates on the standard protocol for Wi-Fi networks 802.11b/g/n, IEEE 802.3 and communicates with all available networks on all channels of the Wi-Fi range.
The length of the USB cable is 5 meters. If necessary, you can expand it with a USB extension cable.
If you are going to install the device outdoors, I would recommend that you secure the wire to the bracket in order to prevent water from flowing down the cable from the antenna during rain. I had such a situation when I came home and found a puddle on the window.
Data transfer rate: 150 Mbit/s. Which is quite enough for any multimedia, surfing or games.
Using a computer and the included disk, you can set up a network not only as a user to receive the Internet, but also turn your PC into a router or router.

So, let's summarize:

Model: LG-N100.
Color: white (milky).
Data transfer rate: 150 Mbit/.
WI-FI Transmission Protocol: 802.11b/g/n, IEEE 802.3
Package weight: 0.513 kg.
Product size: (LxWxH): 120x120x220mm
Package size: (LxWxH): 95x140x230 mm

The kit includes:

USB Wi-Fi antenna with 5 meter cable – 1 pc.,
Antenna holder – 1 pc.,
CD with drivers and software – 1 pc.,
Operating manual (in English) – 1 pc.

To everything I want to add that I bought this miracle for 1000 rubles, give or take. There are also cheaper models, but with a shorter cable length and shorter range, be careful! Order from trusted sellers.
Using this example, I want to say: I personally don’t like expressions like “it’s worth the money,” like you threw away your money, but not in vain, again like... For me it’s like this: either you’re completely satisfied with what you bought, or you’re not!
I bought this antenna and am 100% satisfied, I have no unpleasant experiences in connection with this purchase.
That's all I have) Thanks for watching! If you liked it, please give it a like. All questions are in the comments. Links are in the description under the video. Until next time.
Wi-Fi-USB antenna -

Task: insert the Wi-Fi USB adapter into the jar so that its internal antenna takes the desired position.

Like that:

We will need:
1) USB Wi-Fi adapter
2) USB cable (extension cable)
3) A jar with a diameter of 80-100 mm. A can from Nescafe or Agushi will do.

The tests were carried out on my windowsill. The signal sources were access points of unknown location, most likely not in line of sight. That is, with a reflected signal, for which this antenna is not particularly designed. The result pleased me - without an antenna I was able to catch a signal from 2 points, with an antenna 11. The signal growth is approximately 10 dB, which by the way corresponds to the performance of a can antenna connected to an external connector. I tried to move the adapter in the can antenna along the axis of the can - there was no improvement. I tried sticking the WiFi adapter so that inside the can there was only the part with the built-in antenna - it didn’t get any better. I tried turning it sideways, “face”, backwards (back) - I didn’t notice much of a difference. Well, maybe the “back” position of the USB adapter is a little better.

At the same time I decided to check whether the diameter of the jar is so important. Having inserted a Wi-Fi adapter into an Agushi jar with a diameter of 100 mm, I was very surprised by the result! Judging by the table (in the article about can antennas), a 100 mm can is not suitable for the frequency at which Wi-Fi operates, but measurements have shown that a baby food can is even better than a “correct” can.

Here are the measurement results, albeit rather approximate, but they give a general idea. Please note that all this is only true for USB. Wi-Fi ZYXEL G-202 EE, and with your adapter another position in the can antenna may be advantageous. Although the difference is small and a much greater signal increase can be obtained by looking for a better location of the can.

Signal 1

In general the conclusion is this: to strengthen a weak WiFi signal - the bank is the easiest to implement and free option (it is assumed that you already have a Wi-Fi adapter). At least you can understand whether it is worth making an even better and more difficult to manufacture antenna.

Now the manufacturing details:

1) that's all we need: a jar, a tape measure (or ruler), scissors or a knife, and table with data for our can (for a can with a diameter of 100 mm, the distance from the bottom to the center of the hole is 44 mm), pliers and a screwdriver (optional)

2) Having measured the required distance from the bottom, we make a hole with a knife or scissors, a little longer than the width of the USB connector, and simply bend the tin inward or outward. There is no need to trim the edges, they will be useful so that our whistle does not dangle in the jar. Bend it as conveniently as possible; in my opinion, the USB adapter holds tighter when facing outward, but there is a greater chance of injuring your hands.

3) Insert the adapter and connect the USB cord to it

4) DONE!

All that remains is to secure the can in the desired position, but this is not such a problem, because... it weighs almost nothing. By the way, a nylon lid from a jar may come in handy - attach it to something with 1-2 screws and insert the bottom of the jar into the lid. You can use glue for reliability.

Video with a more powerful antenna:

Buy a USB adapter wireless network"dongle". Thanks to this finger-sized device, the computer is able to connect to Wi-Fi networks. You need it even if your computer already has a built-in wireless network adapter.

• For best compatibility, buy a Wi-Fi adapter that also works with the 802.11b and 802.11g standards.
• To find out the cost, visit Google Commerce or Pricewatch. Simple adapters that are quite effective at close range will cost about $15-$20.
• Form matters. For optimal savings, choose a small finger-shaped adapter. The larger "squash mouse" adapters ($50 - $60) are generally more sensitive and powerful. Although they can be difficult to install, they perform better in more challenging environments.

We buy a passive USB extension cable. You need a Type A (male) - Type A (female) cable. You can purchase it at a one-price store, local computer store, or online. With it you connect the USB Wi-Fi adapter to USB port computer.

• The antenna is directional, so you need to place it so that it faces the wireless access point. Make sure the cable is long enough ( maximum length 5 m) to place the antenna in the required location.
• If necessary, you can connect multiple extension cables.
• Active USB extenders (~$10 USD) allow you to use cables longer than 5m, allowing you to mount the antenna even higher for best results.

Take a mesh colander. It is best to use an Asian "scoop" type cookware (like a wok, but with a mesh), which is used for frying. Its shape is perfect for our purposes and it also comes with a wooden handle!

• You can also use a sieve, steamer, pot lid and lamp shade, provided they are hemispherical in shape and made of metal. Any mesh piece of parabolic shaped metal will do - the larger the better the signal, although this may make installation more difficult.
• For larger options, old parabolic ones are suitable TV antennas or mesh umbrella frame. Although they will give greater signal gain, there may be problems with installation and aerodynamic drag, so a 300mm diameter seems to be the most practical.
• Flexible leg from table lamp will allow you to carefully install and point your antenna.

We assemble the system. Using wire, adhesive tape or hot glue, attach the Wi-Fi adapter and USB extension cable to the plate.

• The adapter must be installed in the center of the dish's "hot spot" - radio signals enter the dish and are reflected to the center a few fingers above its surface.
• The best location for the adapter can be determined through a simple experiment. One method is to cover a plate with aluminum foil to determine how the sunlight reflects on it - the most illuminated point is the focal point of the plate.
• You may need a small rod to secure the adapter in position.
• Alternative securing methods: Use string tied to the front of the plate in a web pattern, scraped-out plastic garden hose fittings, or even chopsticks!

Antenna connection. Connect one end of the USB extension cable (male) to your computer, and network parameters configure it as a Wi-Fi adapter.

We will need:
CD box.
Copper wire with a diameter of 2.5-3 mm.
A compact disc (plays the role of a reflector). You can also cut a circle out of copper yourself.
Antenna cable.

We assemble the antenna itself, observing the dimensions.

Then we drill a hole in the center of the box with a diameter for the TV cable.

And we cut two slots, at 90 degrees to one another (the slots are needed to fix the antenna).

The main thing is to maintain the distance between the reflector and the antenna, this is exactly 15 mm.
We also make four holes in the box (we will place clamps in them for further fastening to the mast).

Now let's glue the reflector to the bottom of the box.

We pass the cable through the back and solder the antenna (there is no difference between where to solder the central or screen wire).

We insert the antenna into the slots and fix it with hot glue on both sides.

Now let's connect the WI-FI adapter.

We strip the cable so that the screen braid is longer than the central wire.
From the central cable we leave approximately 5 mm of wire insulation.

Using an awl or a sewing needle in the center of the central braid (next to the wire), we make a puncture into which the central wire of the adapter antenna will go.

Unscrew the antenna from the adapter.
I cut a small piece of tube from an old marker (this will be an adapter and a retainer between the adapter and the cable).
