We choose an inexpensive and good Wi-fi adapter. Choosing a budget adapter for hacking Wi-Fi

Modern Wi-Fi adapters for a computer, the rating of which allows you to determine the choice of the appropriate option, are designed to communicate with a wireless network or improve the signal for a laptop.

Compact devices connect to USB inputs computer technology and operate in the same ranges as standard ones.

And their cost is not comparable with the benefits in the form of improved quality of Internet surfing, comfort gameplay or video playback speed.

Need for a gadget

Before moving on to choosing the best ones this moment wireless adapters, it’s worth figuring out whether PC users or .

As a rule, the need to purchase a device arises if you have the following equipment:

• stationary or mobile computers. The solution may be to locate the same distance from each PC or run cables - but sometimes it is much easier to provide communication using an adapter.
• A laptop whose built-in adapter quality is too low for a fast connection to the Internet or home network.
• A laptop and even a tablet (with OTG technology support) that do not support the 5 GHz band. Connecting a wireless dual-band adapter to them will increase the data transfer speed from 300 MB/s by 2-3 or even 5-6 times.

Some budget Wi-Fi adapters do not support the 5 GHz band.

Therefore, with their help, you can solve problems with connection and data transfer only for desktop computers - laptops are already equipped with built-in modules with similar parameters.

But the cost of such single-band adapters is several times lower, and they cope with most tasks only slightly worse than more powerful and expensive models.

TOP 7 best models

Trendnet TEW-809UB – the best full-size model

On the modern electronics market you can find a wide range of compact and inexpensive Wi-Fi adapters for your computer.

But, if you don’t want to save space and money, but get a good signal, you should turn to the dual-band model Trendnet TEW-809UB, full-size and powerful, but installed separately (connected to a PC with a cable) and at a price comparable to an average router.

The maximum data transfer rate is 1300 Mbit/s in the 5 GHz band.

• impressive design, at first glance you can believe in its high performance;
• signal reception even through brick load-bearing walls and at a great distance from the signal source;
• no strong heating during operation;
• The adapter comes with all standard drivers, which eliminates the need for lengthy searches for suitable software on the Internet.

Victor K.: Powerful device. Allows you to connect to Wi-Fi not just from the next room, but even in the next building. The speed is excellent, suitable for Internet surfing, regardless of how busy the web page is, for 4K video and for games. There are no downsides other than the price.

ASUS USB-AC68 – the best portable adapter

The USB-AC68 Wi-Fi adapter operates in two bands, providing speeds up to 1.3 Gbps. Good power and signal amplification are provided by two complete antennas.

• Possibility of connecting to a USB port either directly or using the supplied cable.
• high data transfer speed;
• compact dimensions, despite the presence of 2 antennas.

• low performance in the 2.4 GHz band and low cost. X
• although its price is quite consistent with its capabilities - you won’t be able to find the same high-speed and compact adapter even for a large amount.

Sergey L.: Fast, compact, convenient. It provides the same speed that your Internet provider provides – even with a larger margin. The antennas are interesting - they are easy to lift and really amplify the received signal. I didn’t find any shortcomings with the device - except for the relatively high price, but it more than pays for itself in quality.

Edimax EW-7833UAC - the best mid-class model

Anatoly L.: I am completely satisfied with my purchase. Especially since it operates in the 5 GHz band and squeezes everything out of my tariff plan(100 Mbps). The design, of course, is simple, and with prolonged use it can get very hot, but the power level is stable, and the adapter takes up no more space than a regular one.

Linksys WUSB6100M – the best ultra-compact model

In the modern world, a Wi-Fi adapter for a computer has become an indispensable thing. It is easy to set up using a router and a USB port. Anyone who is just planning to purchase a network module should familiarize themselves with the types and rules for choosing a device.

Modern network adapters are available in several types:

1. External wifi adapter. Connects via cable or USB port. It does not provide the highest Internet transmission, but it is affordable, easy to use and reliable.
2. Internal wifi adapter. Built-in modules are connected inside the system unit. To do this, use the PCI Express connector. It is rare to find a Pci standard that is already outdated. The device provides a reliable network connection and excellent information transfer speed. Their cost is higher than the first type of adapters and depends on the manufacturer.
3. Card. Designed for PC with a special slot. It picks up the signal well and is reliable in operation.

Having decided on the type of network module, it’s time to move on to choosing a device for a desktop computer.

Rules for choosing a Wi-Fi adapter for a computer

When choosing a device for wireless Internet, you should focus on the following characteristics:

1. Compatibility with technology. The network module is connected through the installation special driver. The instructions for the adapter must indicate the compatibility parameters of the device with one or another software. There are both universal models and branded products for a specific computer on sale.
2. Standard. The volume of data transfer per unit of time depends on it. The maximum value reaches 300 Megabits per second. It complies with the 802.11n standard. The 802.11a standard transmits up to 54 Mbps. It is recommended to buy an adapter with the same transfer speed as the router. If you buy a device with a lower standard, the Internet speed will be limited.
3. Frequency. Typically, models operate at frequencies from 2.5 to 5.5 GHz. The indicators on the adapter and router must match, otherwise malfunctions may occur.
4. Power. This parameter is responsible for the quality and stability of the connection. For good wireless communication It is recommended to choose adapters with a power of 16 to 20 dBm.
5. Access code. It is desirable that the device supports special encryption protocols such as WAP2 or WAP. This will provide protection against hacking.
6. Action distance. The specifications for the adapter indicate the operating range of the device in an apartment and in open areas. Five meters is enough for home use.

Connecting and setting up a wireless Internet adapter

Connect the Wi-Fi adapter for the PC as follows:

• insert the device into USB port system unit;
• wait until the new device is recognized;
• if the module was not installed itself, use the disk included with the adapter and install the driver from it;
• in the list of Wi-Fi icons that appears, select a router and connect to it by pressing a button;
• enter a password and use the wireless network.

If your device has the WPS function, the connection to the router will occur automatically. To do this, just activate the mode on the router and press the WPS button on the router body.

Connection software

The adapter is installed and configured according to the user instructions included with the device. A disk is usually included with it, which contains all the necessary settings. When installing it, you need to select the name of your module. The whole process is quite simple. The main thing is to follow the prompts on the screen.

If installation disk is not included with the adapter, the driver must be downloaded on the Internet from the manufacturer’s main website. To do this, you will need information about the device model.

Some adapters do not require any software download. After installing the disk and connecting the Wi-Fi adapter to the system unit connector, you can check the operation of the device.

Possible difficulties during installation and configuration

In some cases, buyers encounter problems when installing the module.

These may be the following situations:

1. The PC has found an access point, but the network quickly disappears. It is possible that the adapter turns off automatically due to the fact that it is adapted to a certain power supply mode.
2. The connection is not recognized. The adapter is probably not compatible with the installed driver.
3. The computer does not see the wireless network. This happens if the driver is taken from a “left” source.
4. The adapter takes a long time to recognize the IP address. This may be due to incorrect router settings.

If the problem is related to the gateway settings, it makes sense to reset them to factory settings and try again.

Rating of Wi-Fi adapters for computers

The rating will help you choose a Wi-Fi adapter for your computer best devices For wireless connection. It is compiled based on consumer reviews, price-quality ratio and brand reputation.

It is better to entrust the choice of a suitable Wi-Fi adapter model to an expert or a store salesperson. To do this, you will need to know the technical characteristics of the computer and router. In any case, the purchase depends on personal preferences and financial capabilities.

In modern world high technology Everyone should know what a WiFi adapter is for. The fact is that we all constantly use wireless networks to solve various problems, but none of us have thought about how such technologies work. Why know this?

Knowledge helps solve everything possible problems with connections. In addition, such knowledge helps to better understand the operation of certain devices. But before moving on to answering the question, what is it for? wireless WiFi adapter, you should understand what it is and how it works.

What is a WiFi adapter

This is a special device that is capable of receiving and sending data packets over broadband radio communications. In other words, there is a certain frequency range, on which it works WiFi technology. And in order to transmit a signal over the air, the data must be converted into a radio wave. Conversely, in order to receive a data packet over the air, this radio wave must be read and digitized.

This is exactly what a WiFi adapter does. In order to catch and send radio signals, it is equipped with a special antenna. And for converting and digitizing data, the module has a chip and software. Therefore, it is very important to install the appropriate driver, since it is the one that controls the operation of the module. Essentially, this is the answer to the question of what and why a wireless WiFi adapter is needed. But this is an incomplete answer. So, here we come to the main question.

Why do you need a WiFi adapter?

As you already know, this device combines two functions:

• Data receiver.
• Information transmitter.

It is thanks to this module that it becomes possible to exchange data packets without a cable connection. It is worth noting that the antenna of the Wi-Fi adapter is capable of covering a fairly large area. However, it can be called big relatively. After all, the range of one access point is about 100 meters.

We all know what a Wi-Fi router is. In addition, we know that smartphones, tablets, laptops and other mobile and portable subscriber devices have a WiFi module. This is what allows you to use your home network. Essentially, this is a regular network card that supports wireless technology. In other words, it can operate on a specific radio frequency.

Absolutely all equipment using this technology is equipped with a wireless module. If we talk about laptops, then, as a rule, in the vast majority of cases, two brands of Wi-Fi adapters are used:

• Atheros.
• Broadcom.

Of course, besides them, there are many more companies that manufacture similar devices, but these two are the most common. And their modules are the most widely used.

Now, knowing that routers use the same wireless adapters, like laptops, smartphones and so on, it can be assumed that to create home networks it is not necessary to buy a router. A laptop or tablet is quite capable of performing the functions of an access point. Moreover, if they are connected to mobile internet, then all network participants will have the opportunity to access global network. Moreover, modern technologies 4G is absolutely not inferior in data transfer speed to a regular cable connection.

It is worth noting that the WiFi adapter is capable of simultaneously receiving and sending information. This means that you can receive the Internet via Wi-Fi and at the same time distribute it to other group members using the same technology.

Ilya 16888

First of all, let’s clarify why an external Wi-Fi adapter is needed, if most laptops and netbooks have had a built-in adapter installed for a long time. The problem is that due to insufficient power of the built-in Wi-Fi adapter or various obstacles (a long distance to the router itself, thick walls), the Internet speed may decrease. To avoid this problem, you can use this same adapter, which will strengthen the Internet signal.

Below is a review and comparison of inexpensive adapters under 1000 rubles, from which we will choose the best one.
First, we will define the criteria on the basis of which we will compare and select the best option.
Manufacturer. At the moment there are several main manufacturers - TP-Link, D-link and Asus. The advantages of this choice are obvious: good service support, a lot of information on the Internet and a well-known brand. The second important criterion is signal strength. Typically ranges from 13 to 28 dBM. Accordingly, the more power, the better for us.
The next important parameter is the connection speed. Speed ​​range from 150 to 300 Mbps. It’s the same here, the higher the better. The presence and number of antennas. They may not exist at all, but their presence increases the efficiency of the adapter. But such structures are very cumbersome.
Connection type. There are two main types: a simple connection via USB and a more complex connection directly to motherboard. There are other connections, for example, via micro-USB, which is especially important with the advent of tablet computers, where there is no full USB input.

Now let's move on to reviewing and comparing our models. Let's divide them into two groups, the first of which will include compact adapters, and the second will include options that have one or more antennas.
Let's start by considering the first group and the most expensive version of the TP-LINK TL-WN821N. Its cost is 740 rubles. It has a 300 Mbps data transfer rate and a transmitter power of 20 dBm. Connects via USB versions 2.0.

The next option is TP-LINK TL-WN821NC. Its cost is 510 rubles. It has the same data transfer rate and transmitter power as the previous version. It also connects via USB, and comes with a USB stand (cradle) as a gift. The other options, although they have a lower price, have insufficient characteristics. From this we conclude that the best compact wi-fi adapter is the TL-WN821NC from TP-Link.
Now let's move on to the choice best adapter from the second group. These adapters are suitable for those who need this device to work at home or in the office.

The first and most expensive representative is TP-LINK TL-WN8200ND. Its price is 930 rubles. The adapter has a data transfer rate of 300 Mbit/s, with a transmitter power of 27 dBm. It is also equipped with two 5 dBm antennas, which are removable. But it connects via a micro-USB connector, which is not entirely convenient.

The second option is TP-LINK TL-WN822N. Cost 660 rub. Data is transmitted at a speed of 300 Mbit/s, but the power is only 20 dBm, although the adapter is equipped with two non-removable antennas. Connection is made using micro-USB. The device also has a stylish design.

Today, full-fledged work on a computer is only possible if you have access to the Internet. Outdated wired connections have lost their ground - just connect to the nearest access point. And if adapters on laptops, as a rule, are already installed by the manufacturer, then for a desktop PC you will need to install a Wi-Fi adapter. Let's figure out how to choose the best model for different requirements.

Types of adapters

First of all, you need to decide on the type of wifi adapter for your computer. According to the installation features, there are two large groups. The first includes external models that are connected from outside the computer. The second group includes internal options that are mounted in the device body. Standing apart are adapters on the CardBus bus that are going out of fashion, but are still found, and are installed in a special connector.

External Wi-Fi adapters

External models are the most popular and easiest to install, since they do not require special knowledge according to the computer device. They can be installed outside the PC without opening the case. It is only necessary that the corresponding port, most often USB, be free.

Sizes may vary: compact models practically do not protrude beyond the port, larger ones look like flash drives. For ease of placement or improved reception (for example, to physically bring the adapter closer to the access point), it is possible to connect via an extension cable.

Since USB is a universal port, external models can be connected to almost any computer – be it a desktop or a laptop. Modern operating systems can recognize most of these models. This USB adapter for a computer is automatically activated after installation.

Please note that the transfer speed of the latest models may exceed the capabilities of older connectors. For example, USB 2.0 will not be enough to use the entire channel of 802.11ac adapters - they must be connected to high-speed USB 3.0 ports.

Occasionally you come across models with an Ethernet connector. In this case, communication is established between the adapter and the computer via a regular network cable.

Internal wifi adapters

Internal options provide for installation in the system unit. From the outside they may not be visible at all - of course, if the model does not have a special external antenna to improve the quality of reception. But even in this case, it is located on the rear end of the PC and is practically not noticeable. So what if appearance computer is critical, and it is also undesirable to occupy USB ports, then it’s better to stick with this option.

Please note that if installed completely internally, the signal may not be transmitted as the metal parts of the housing will block the signal. Models with an external antenna almost never have such difficulties. Some adapters also provide for replacing the external part with a more powerful antenna.

A typical installation option is inside the system unit in a PCI Express slot, like for a regular network card. The PCI standard is less common because it is already becoming obsolete. At the same time, portability suffers, since you cannot quickly move the adapter to another PC, nor can you easily move it to improve the quality of reception.

Wi Fi Card Bus adapters

The rarest type of adapter, which has practically ceased to be produced. To install it you need a special connector. The advantages include compact dimensions and very easy setup, the disadvantages (along with low prevalence) are low power. Most often, such models are used in laptops - for example, when the main adapter fails.

Wi-Fi adapter D-Link DWA 525

An available internal model for connecting a PC to a network is DWA 525 from the company. To connect with Wi-Fi router can use 802.11 b/g/n protocols, which gives a maximum speed of 150 Mbit/s. In most cases, this is enough for reliable operation in an apartment. The model supports WEP/WPA/WPA2 encryption. For installation, you need a free PCI Express or PCI slot - both modifications are available, so you need to check which model you are purchasing.

The antenna on the adapter is removed. The manufacturer guarantees that the device will work in OS from Windows XP to version 8 inclusive.

WiFi adapter ASUS PCI N10

Another internal adapter. The characteristics are similar to the previous model: installation in a PCI port, transmission speeds up to the same 150 Mbit/s thanks to an external antenna and the ability to work within 802.11n. For quick setup connection, you can use WPS, and communication will be automatically carried out over an encrypted channel. An additional plus is that the adapter can work as an access point.

Wi-Fi adapter for desktop computer PC

If the signal is weak, then the laptop can be moved closer to the access point. This trick will not work with a desktop computer. Therefore, it is necessary to immediately select a model taking into account the conditions at the site of its installation. So, in an apartment with a complex layout or thick walls, a more powerful option may be required. But you don’t have to limit yourself to an assortment of only external models or modify an existing one if the antenna cannot cope with reception.

How to choose a Wi-Fi adapter

If you have already chosen between internal and external option installation, it's time to get to know each other better technical characteristics devices. Pay attention to the following key points when choosing a Wi-Fi adapter for your PC:

• compatibility with existing devices (primarily access point - router);
• standards support as it determines the transfer speed;
• frequency used;
• transmitter power in the adapter;
• the ability to encrypt the connection;
• receiver range.

Don't limit yourself to the speed written on the package. This is the theoretical maximum limit for this model. The factors mentioned above also influence the actual speed.

Also pay attention to your future place of work. If system unit hidden in the depths of a massive table, then it would be logical to try to move the antenna higher using an extension cord.

Sometimes it is recommended to use an adapter from the same company that manufactured your router. There is a bit of common sense in this: the manufacturer can test the equipment for stability collaboration, and the software interface will most likely be similar. In practice, popular models quite successfully connect to routers from other manufacturers. Difficulties due to different manufacturers are extremely rare, usually with old equipment.

Compatibility

First of all, check whether your computer has an appropriate free port. The PCI Express adapter cannot be placed in a USB connector, as well as in a regular PCI, and a model with an Ethernet connection cannot be placed in a Card Bus slot. As for the operating system, everything is simpler: popular models support Windows lines and Mac OS at a decent level. Full list indicated on the packaging or in accompanying documentation.

If you need to connect a specific device (for example, on an old Windows versions or a rare OS), first make sure that suitable drivers are available on the manufacturer’s website or on the CD supplied with the kit.

Standard

Support for a particular communication standard determines the possible speed modes of communication between the adapter and the router. To work on high speed support for modern 802.11n or 802.11ac is required. If you use a device that supports only g or even b standards, then the connection speed will be very, very limited - it only makes sense to do this if the router does not support faster options.

If you connect using a slow adapter, the router will automatically go into reduced performance mode. At the same time, all other connected devices will also be forced to work at a lower speed.

The minimum reasonable requirement is to support version n of the standard. It provides speeds of 150 or 300 Mbps depending on the model. This will be enough for comfortable surfing the Internet and for watching video content without long waits.

The 802.11ac standard features support for the 5 GHz frequency and is gradually gaining popularity. It provides data transfer at speeds of up to 10 Gbit/s. True, such speed may not be useful in home equipment. Unless you want to choose an adapter with an eye to the future or for professional purposes such as participating in online gaming tournaments or regularly working with large amounts of data.

Frequency

Wireless equipment uses two different frequencies to operate. Older or cheaper models usually use only the 2.4 band, newer and more expensive ones can operate in both bands or exclusively on 5 GHz. Therefore, you need to make sure that the adapter and router can “make friends” and use the same frequency for communication.

Advantages increased frequency– increased data transfer speed between devices. In addition, more channels can be placed in this range without overlapping each other. That is individual points access devices, even if they are close together, will not interfere with each other’s data transmission. And since such devices are more expensive, the radio air in this range is less busy, which has a positive effect on the stability and speed of the connection.

However, this approach also has a drawback: the high-frequency signal penetrates less well through walls and other obstacles. Because of this, the radius of reliable reception, all other things being equal, may be smaller. If possible, it is recommended to test both connection options and choose the best one for your specific computer.

Transmitting module power

The transmitter power of a Wi-Fi adapter for a computer determines the range over which the radio signal will propagate. The higher it is, the more confidently the connection with the router will be maintained. This means that the data speed will be higher. On the other hand, legislation limits the maximum power.

If there are obstacles between the computer and the router, it is better to focus on values ​​of about 20 dBm. In line-of-sight conditions (for example, if the access point is in the same room), less powerful models can be used.

Access encryption

Compound wirelessly due to the use of radio waves, it has a significant drawback: if you have the equipment and are close to the transmitter, the signal can be received by anyone. That is, the data is actually transmitted in an unprotected environment. So it is necessary to take care of encrypting access so that no one else can connect to the channel and view what is being transmitted on the radio.

The modern WPA2 standard is a whole set of technologies aimed at protecting data. A strengthened version of the WPA3 standard has just been announced. But it is better to immediately abandon the outdated WEP, since hacking technologies have already been developed for it.

Range

An important parameter is the signal reception range. After all, Wi-Fi is of little use if you have to spend all your time near the access point. The more powerful the transmitter than better antenna, the greater the distance you can confidently maintain radio communication. However, it is worth keeping in mind that the manufacturer indicates this parameter for ideal conditions with numerous reservations. The fact is that the range is affected by the presence and material of the walls between the router and the adapter, the degree of radio noise (the number of routers or other radio equipment nearby), the frequency range used, etc.

Other parameters

Please note that it supports MIMO technology. Despite the ridiculous abbreviation, it allows you to improve the signal: instead of using one, you can use several antennas, both on the router side and on the adapter. In the standard version n, 4 pieces are allowed, and ac - 8 at once. Since in this case they all work in parallel, the speed increases several times. This also has a positive effect on the stability of the connection. True, such adapters are somewhat more expensive.

If you also need to distribute Wi-Fi to devices nearby, check SoftAP support - this mode allows you to use the adapter as an additional signal transmitter. Then you can install one powerful module in your PC, and connect your smartphone or tablet to it.

If an adapter is purchased to connect devices directly, make sure it supports the appropriate technology. For example, it could be Wi-Fi Direct or Miracast. Otherwise, the adapter will be of no use.

Setting up and connecting a Wi-Fi adapter

Next, we’ll look at how to configure the purchased adapter. First you need to connect it to the appropriate connector. To connect via PCI or PCI Express, you will need to open the system unit. Then you need to carefully, without excessive pressure, place the adapter in the slot and make sure that it is fixed there. If the module has an external antenna, you need to remove the plug from the rear wall and replace it with the bracket that comes with the adapter. WITH external models everything is much simpler: you just need to connect it to a free USB.

Popular models are well recognized by modern operating systems. The OS can independently install all the necessary drivers and activate the new device. In this case additional customization may not be required - the computer will simply have the ability to connect to wireless networks using standard methods.

If the system fails to install in automatic mode, we need to help her. Drivers can be found on the disk (if it was included with the device) or the manufacturer's website. To activate additional functions, such as Wi-Fi distribution from a computer or fine settings transfer parameters, a special proprietary utility may be required.

First actions

After installing the software, check for connectivity. If the drivers are installed correctly, the computer will be able to connect to your router. Please provide the correct access point name and password. If necessary, configure interaction with the router - select the desired frequency range and the required standard, optimize communication using proprietary utilities.

Network problems

Sometimes after installation the network is unstable. The reasons may be different: incorrect configuration of the router or the computer itself, problems with the software, or even a malfunction of the adapter. This manifests itself in the fact that the connection is interrupted some time after connection or the computer does not see Wi-Fi.

The reason why this happens may be trivial: the power saving mode for the adapter is activated. This is often found on laptops; the OS optimizes energy consumption by turning off everything “unnecessary”. To check, you need to open the settings in the properties of the wireless connection. Then on the power management tab you need to uncheck the box that allows you to turn off the device.

Problems with the router

You also need to check whether other devices can connect to the router. For example, using a smartphone or tablet. If another device successfully establishes a connection and maintains it stably, it means that the router itself is working correctly. Also try rebooting your router.

Otherwise, you need to check the configuration of the access point: is it using a compatible standard, is the same radio channel selected (if disabled automatic setting), whether the correct password is specified. As a last resort, you can reset the router to factory settings and then configure it again, checking each step.

It is also possible that the router firmware needs to be updated. In this case, you will need to download it from the manufacturer’s website and then update it through the router control panel. Detailed instructions For specific model usually listed in the user manual.

If all of the above measures do not help, check that the device is operating normally. For example, to check, contact service center manufacturer.

Software

Also, the problem may lie in an outdated wireless connection profile - if the router settings have changed, and operating system“doesn’t know” about it. Then you need to delete the profile, after which it will be created again. First, launch the Command Prompt (CMD), then run the following command, specifying the profile name instead:

netsh wlan delete profile name=

After this, you will need to re-enter the password when connecting to the router.

If you see a message that your connection is restricted, you can reset your TCP/IP settings to their default values. To do this in command line the following technique is used:

netsh int ip reset c:\resetlog.txt

After reboot, check the connection.

If this does not help, check that the driver is installed correctly. In the OS control panel, select Device Manager, then in the list network adapters check yours. Open its settings and try reinstalling the driver (uninstall and reinstall). Use drivers from the official website. You can also try installing more old version drivers (with a lower index).

Adapter failure

When the above measures do not help or the adapter is not even detected by the system, perhaps the problem is in the device itself. To be on the safe side, you can try installing it on another computer. If it works there, you need to check your computer settings. If the adapter refuses to function on another machine, you need to replace it (if the warranty is still valid) or repair it.

Happy Internet to you!
