There are problems with the wired network adapter. How to Choose a Network USB WiFi Adapter for a Computer or Laptop. Wi-Fi Card-Bus adapters

Nowadays, almost all devices are equipped with WiFi wireless Internet. But there is a separate niche of devices on the market that are not equipped with wireless Internet - these are personal computers. To connect them to the wireless Internet, you will need WiFi devices. WiFi on your computer may be needed in several cases:

• There is wireless Internet in the house, for example, on a smartphone or tablet, and it must be connected to a PC that does not have WiFi;
• The computer already has Internet, but I want to distribute it throughout the apartment to save time and money on an additional tariff.

What is a WiFi adapter

A WiFi adapter is used to implement the wireless network function on devices that do not support WiFi. It allows the computer to receive a signal from a wireless network. Now there are two types of adapters: the first are capable of only receiving a signal, the second can operate in signal reception and signal transmission mode. Adapters that have the SoftAP function built-in allow you to create a WiFi access point on your computer.

How to choose an adapter

When choosing a WiFi adapter, it is important to consider the connection method. There are so-called USB adapters that are very easy to use as they can be easily removed and connected to another computer. There are adapters that use the PCI-E interface. This is a set of chips that are inserted into special slots in the system unit. Before purchasing such an adapter, you first need to check the system unit for free PCI slots where you can connect the device.

One of the most important criteria in choosing an adapter is the WiFi standard. Today, the recognized wireless communication standard is 802.11n, which guarantees fast data transfer of up to 300 Mbit/s. In addition, there are new communication standards such as 802.11ac. This latest standard can transfer data from 3000 Mbps to 10 Gbps. But for home use, there is no need to pay extra money for speed, since 300 Mbit/s is quite enough.

It is also worth paying attention to the transceiver. The recommended transmitter power is 20 dBM. If the original transmitter power is lower, the signal will be very weak, even if the Internet source is located within the apartment.

If the appearance of the adapter is not too important, then you can purchase an adapter with an external antenna. It is able to receive a signal much better, but has large dimensions. In addition, there are devices with removable external antennas.

When choosing a WiFi adapter, you should pay attention to their frequency. Manufacturers began to produce devices with a frequency of 5 GHz, but now adapters operating at a frequency of 2.4 GHz are still common.

It is also worth paying attention to the presence of the SoftAP function in the adapter. It is recommended to purchase adapters from the same company as the routers that are in the house, as their compatibility will be much better. This will help avoid various kinds of connection problems.

The adapter is installed in a special slot on the computer. After installation, the adapter must be configured - install the necessary software for wireless data transfer. The driver can be installed from the disk that is included with the device, or by downloading from the official website. After installing the driver, you need to configure the network, select the necessary parameters and access points.

Types of adapters

External WiFi adapters

In appearance, such adapters resemble a USB drive. The price of a standard USB adapter ranges from 700 to 1000 rubles. If you search hard, you can find devices within 300-400 rubles. This adapter can be connected to a regular USB port or a USB cable.

The best USB WiFi adapter in my opinion in terms of style and design, as well as with good transmission speed and 5dbi antenna Here .

Internal WiFi adapters

To connect such an adapter to your computer, you will have to slightly disassemble the system unit. The adapters are very easy to connect, and they are much larger than external adapters.

Many people are afraid that when switching to WiFi, the speed of downloading files will drop significantly, but in fact this is not the case. Typically, each WiFi adapter has its own bandwidth. Let's say the Internet connection speed is 1 Mb/s, and the adapter bandwidth is 54 Mb/s. Based on these data, we can conclude that the Internet speed will not drop, because the adapter’s bandwidth is much higher.

Wi-Fi Card-Bus adapters

Such adapters are designed for laptops and PDAs that have a special PCCard slot. Such adapters have a built-in antenna, they are very compact and do not require lengthy setup.

WiFi adapter D-linkDWA 525:

The cost of this model is at the level of 500-700 rubles. The characteristics of the model are as follows:

• Supported wireless standards: 802.11b, 802.11g, 802.11n
• Maximum data transfer rate: 150 Mbit/s
• Connection interface: PCI
• Supported information security technologies: WEP, WPA, WPA2
• Number of external antennas: 1 detachable antenna with R-SMA connector

WiFi adapter ASUS PCI-N10

The cost of this adapter is 500-600 rubles.

The adapter is 802.11n standard and has a PCI interface. It allows you to connect a personal computer to a wireless Internet network. The adapter can be installed in any 32-bit slot.

Specifications:

• Encryption support 64/128-bit WEP,WPA2-PSK,WPA-PSK,WPS;
• WPS (Wi-FiProtectedSetup) button – quick setup of a secure connection;
• Software AP allows the WLAN adapter to act as a virtual access point.
• Standard 802.11n (150 Mbit/s) with PCI interface.

Modern USBWiFi adapters provide wireless signals from access points, routers and other devices. Many computers and laptops are already equipped with WiFi function, but if it is not available, you can use a USB adapter. These devices are similar in appearance to small flash drives, but they have different technical characteristics.

You should also take a closer look at the parameters that characterize the antenna power (ideally, at least 20 decibels). Thanks to this, it will be possible to clearly capture even the weakest signals. The presence of a connector for an external antenna will be an additional advantage. The antenna can be purchased as a separate device or as a kit.

In some adapter models, two antennas can be raised in operating mode, which will enhance the signal quality and increase the data transfer speed. You can purchase compact models in which the antennas are built into the device body itself. The case should preferably have ventilation holes through which heat will be removed. Due to the absence of such holes, the performance of the device may deteriorate significantly.

The main characteristics of the adapter can be found on its packaging. The front side contains information that lists the standards that the device supports, special features for quickly setting up the adapter, and the choice of protection method. Apart from this, one of the most important points is the support for multiple connection modes between two computers.

One of the most popular models on the modern market are the D-Link DWA-127 and D-Link DWA-566 adapters.

The DWA-127 adapter has a built-in antenna that provides a large wireless connection area, and a special hardware WPS button that automatically configures a secure WiFi connection. Thanks to this adapter, a high-quality connection with devices of standard standards (labeled IEEE 802.11) is ensured.

DWA-566 is a wireless adapter that allows high-speed connection of computer devices to the network. There is no need to install additional Ethernet cables. This adapter fits all standard slots (x1/x4/x8/x16), has two detachable antennas (with a gain of about 2 dBi), is capable of operating in two bands: at a frequency of 2.4 GHz (marking: IEEE 802.11; b/ g/n) and at a frequency of 5 GHz (marking: IEEE-802.11; a/n). Due to these conditions, the wireless connection can reach speeds of up to 300 Mbit/s.

These adapters can operate using WEP/WPA/WPA2 encryption protocols, are fully suitable for secure wireless networks and provide reliable security for transmitted data.

The package includes the D-LinkManager WC utility, which allows you to configure convenient parameters and saves the most frequently used profiles. The DWA-127 costs about $22, and the DWA-566 costs about $47.

Setting up a WiFi adapter on a computer

To configure the WiFi adapter for the first time, you will need the following components:

• The WiFi adapter itself;
• Disc with drivers and other software;
• User guide.

First you need to install the device into a USB port. It is best to use the ports that are located on the back of the system unit, as they are connected to the motherboard and are already completely ready for use. You can use the ports located on the front side of the system unit, but first make sure that they are in working order. After connecting the device, a message will appear indicating that a new device has been detected. Next you need to install the software and driver package. You should also install software utilities; they will not be superfluous, since with their help you can adjust network parameters and carry out more fine-tuning. Next, you need to look at the display of network connections (the network connections icon is located at the bottom of the taskbar). The drop-down window for network connections will list a list of devices that are connected to the PC; you must select the one that is currently installed. After this, you need to click on the new connection with the left mouse button. In the available network connections window that opens, click on the new network to enter the password.

Basic mistakes when choosing a WiFi adapter

One of the most common mistakes people make when shopping for a new device is that they unconditionally trust sales assistants. In reality, the seller, as a rule, tries to sell not the model that best suits the characteristics of others, but the one for which he can get his percentage. That is why, before purchasing, it is recommended to familiarize yourself with the functionality of the selected models and read reviews about them on the Internet.

Another mistake is that people think that all adapters are essentially the same. In fact, different models differ from each other in power and characteristics, even from the same manufacturer.

Many people are confident that there is no need to spend money on expensive devices. Of course, you can buy an inexpensive device, but its power will be much less than that of one for which you will have to overpay only a few hundred.

In addition, it is also worth noting one of the biggest misconceptions that absolutely all equipment produced in China is of poor quality. In reality, the quality of products does not depend on where the manufacturer is located, but on who ordered the production of these products and from whom.

As practice shows, absolutely any user can configure a wireless network. WiFi adapters are reliable devices that are becoming indispensable for people. Buying an adapter can save you from many inconveniences, such as a large number of wires.

Q. What is a Wireless LAN Adapter?

A. A wireless LAN adapter is a special device that provides communication between a wireless access point and a device: computer, laptop or netbook, tablet PC, smartphone.

Modern portable devices, such as laptops, tablets and smartphones, have this miracle module “on board”, that is, they are already complete and do not require the installation of third-party modules and brackets. Of course, it happens that a laptop or netbook does not have enough power of the internal wireless network adapter to “reach” the access point or uses an outdated B or G standard, the throughput of which is significantly less than or equal to 54 Mbps. Often, such moments upset owners of old equipment. There is only one way out of this situation - purchasing an external wireless network adapter. The USB adapter has good power and uses the modern N standard, which allows you to get speeds within a wireless network of up to 100 Mbps. Of course, the range also becomes larger, which allows you to connect to access points at a distance of up to 100-150 m.

With personal computers the situation is a little more complicated. There are 2 main types of wireless network adapters available for PCs: the most popular is with a USB interface and its older brother is the PCI adapter, which is installed in a special slot on the motherboard.

PCI adapters are older and an order of magnitude cheaper than USB adapters, less convenient, although they are simply not intended for portability, and cause horror in the eyes of beginners or ordinary PC users. Although, it is worth noting that they work stably, quickly, have a good range, and support b\g\n standards. Install once and work happily ever after.

Adapters with a USB interface are more expensive only because of their “friendliness” to all categories of users. Because nowadays everyone knows how and where to “stick” a flash drive. These devices work with all standards: b\g\n. They can have sizes not exceeding the size of the most ordinary flash drive.

So, wireless LAN adapters can be internal or external, have different power and bandwidth, and work with different standards: outdated b/g and currently relevant n.

There are two main types of network: wireless and wired. Network adapters can be used with both types of networks. At the same time, there are a larger number of network adapters for wireless networks, since there are more varieties of such networks.

Using an adapter, you can connect your computer to the network using a cable. For wired networks, a device is used that is a USB dongle with a special port for an Ethernet cable. This cable can connect, for example, a router and an adapter.

The adapter may come with software, but most modern operating systems recognize the USB adapter and themselves find the drivers necessary for its operation.

But most often, a network adapter means a device for wireless networks. Such adapters are popular due to their portability. They allow the computer to join a nearby wireless network.

The wireless network adapter resembles memory cards or flash drives in appearance. This is a small USB device with a light indicating that it is charged and ready to use. When it is connected to a computer, it scans the Internet channels of local providers and tells the computer software about the presence of networks. The computer, in turn, shows these networks to the user. For your computer to connect to the network of interest, just click on its name and enter the password, if required. The next time you turn on the computer, it will automatically connect to this network.

Many modern computers already have wireless network adapters integrated into the machine. They are microchips.

Finally, there are network adapters that are purely software. They simulate the functions of a network card. They are called "virtual network adapters".

Why are network adapters needed?

Most laptops have a built-in wi-fi card or wireless network card. But sometimes this card doesn't work. This is especially true when wireless network standards change to a new and faster connection protocol. Then old cards that support outdated protocols will not work with a router that supports the new standard.

When buying a new network adapter, you should pay attention to the protocol it supports. This small and necessary device can be found in any Hi-Tech store.

When the internal network card does not support the new standard, a new network card can be an alternative to the network card. It is fairly easy to replace on a desktop computer. But in laptops and notebooks this is much more difficult to do. In such cases, it is more convenient to use a network adapter.

Adapters refers to devices and devices that are completely different from each other in design. They have one thing in common: they harmonize two objects of one kind or another that are not directly compatible with each other.

Older people will remember that adapters are sometimes called pickups used in vinyl record players. In those years when gramophones and gramophones were widespread, many of their owners wanted to listen to records through amplifiers without changing the entire device. To match an existing gramophone or gramophone with an amplifier, an adapter was installed on it. Later, when players began to be initially equipped with piezoelectric or electromagnetic heads, they almost stopped calling pickups adapters. For the same reason, pickups for guitars and other musical instruments are still called adapters today, especially those in the design of which they were not originally provided. Tools equipped with them are called adaptable. Power supplies made in housings similar to enlarged power plugs are also called adapters. They match low-voltage, but sometimes high-current load inputs with the high voltage of the lighting network, consuming little current from it. Anyone who knows that power is equal to the product of current and voltage will understand that this does not contradict the law of conservation of energy. Adapters are also called any kind of adapters. Some of them are designed to harmonize electrical connectors of various designs, while others are used as part of hydraulic, pneumatic, mechanical and other systems. Sometimes even fasteners bear this name. What about the video card installed in your computer? You've probably heard it sometimes called a video adapter. And this is correct, because you cannot directly connect the monitor to the motherboard - only through a video adapter. The only exceptions are boards with built-in video subsystems. True, modern video cards are not entirely suitable for this, since they are separate computing systems, sometimes competing in performance with the computers in which they are installed. A telephone adapter is an electromagnetic device that operates similarly to the adapter for a musical instrument already discussed above. It allows you to coordinate the speaker located in the handset of the telephone with a voice recorder or hearing aid. If a device of an old design is used, the telephone adapter can pick up the alternating magnetic field not of the sound emitter, but of the conversation unit transformer.

Adapter is a polysemantic word that refers to many accessories for technical devices. How to use the adapter depends on what it is intended for.

Instructions

Network adapter - a power supply unit structurally combined with a power plug. The output voltage of this device must correspond to that for which the load is designed, and the maximum permissible output current must not be less than that consumed by the load. Also pay attention to the type of plug and the polarity of the voltage on its contacts. For circular plugs, the polarity is often marked on the adapter and on the load - they must match. Do not plug heavy power supplies directly into loose sockets; use extension cords.

To install a memory card of one format into a device designed for cards of another format, use an adapter consisting of two connectors connected by conductors. There is nothing electronic about it. Today, the most common adapters are for installing Micro SD cards into devices designed for full-size SD cards. Install the card into the adapter, and then the adapter and it into the device, and everything will work the same as with a full-size SD card.

Adapters for pairing different types of connectors are also called adapters. This accessory is useful, for example, for connecting a VGA monitor to a video card with a DVI output if analog signals are output to it. Also, using the appropriate adapter, you can connect headphones with a 3.5 mm plug to a device with a 6.3 mm jack, or vice versa. Choose the right adapter: to connect to the stereo output of stereo headphones, it must be three-pin, and to connect a mono microphone to a mono input, it can be either two- or three-pin.

Power plug adapters allow you to fit plugs with thick prongs into sockets with small diameter holes. Please note that many of them begin to overheat at more than 4 A. Do not use them with high-power devices, especially for long periods of time. Also remember that the device remains ungrounded when using such an adapter.

An adapter is also called an expansion card installed in a motherboard slot. Today, almost all peripherals are integrated into the motherboard or made in the form of external devices connected via USB. The exception is video adapters, and then only powerful ones. If you don't need significant GPU performance, use the video adapter built into the motherboard. And if you cannot do without a separate video card, do not forget to periodically carry out its maintenance: lubricate the fan, clean the radiator, change the thermal paste.

Another type of device called adapters is pickups. They are divided into guitar ones and those intended for use in vinyl record players. In both cases, select the correct amplifier input for connecting the adapter. It must have an input impedance close to the output impedance of the amplifier, and be designed for an amplitude close to that developed by the adapter. Sometimes coordination of amplitude-frequency characteristics (AFC) is also required. If there is no suitable input on the amplifier, then the signal amplitude must either be reduced by an external attenuator (if the input sensitivity is excessive) or increased using an external pre-amplifier (if the input sensitivity is insufficient).

note

Many types of adapters can only be installed and removed when all devices are de-energized.

A tonometer is vital for patients who must constantly measure blood pressure - hypertensive patients, people suffering from cardiovascular and other diseases. The most convenient for use is an electronic device that has a network adapter.

Features of electronic tonometers with a network adapter

Electronic tonometers can measure themselves, so there is no need to use them. Modern models have arrhythmia indicators that indicate an irregular heart rhythm. Such devices have a memory function for recording results, which helps track the dynamics of pressure changes. Automatic blood pressure monitors provide the greatest measurement accuracy.

Almost all electronic devices have the ability to connect a power adapter from the mains, the use of which saves costs. For safe use, the power supply must meet all the requirements specified in the technical specifications of the device. It is recommended to purchase a tonometer with an adapter from well-known manufacturers with a current reserve of up to 800-1000 mA. When connecting the device to the mains, it is not necessary to remove the batteries.

When choosing, you should also pay attention to the cuff. It is advisable that it have a metal fixing device that allows you to put it on without outside help. To obtain the most accurate measurement results, you need to choose devices in which the length of the cuff pneumatic chamber is at least 80% of the length of the arm circumference. The width of the cuff should be approximately 40% of the arm circumference (12-14 cm).

For automatic electronic tonometers, cuffs with one tube are used.

Additional functions of electronic tonometers

Many electronic blood pressure monitors that operate on the network are equipped with additional features. Some models have a system for automatically determining the air injection level. Based on the individual characteristics of the human body, the tonometer can itself determine the level of pressure to which the cuff is needed. For many models of electronic devices, measurement accuracy is achieved by automatically analyzing three consecutive measurements. You can choose an electronic blood pressure monitor with additional functions (arrhythmia indicator, memory, WHO diagnostics, alert timer, calendar and clock).

Some electronic blood pressure monitors can be connected to a printer.

You only need to purchase a tonometer with a power adapter in pharmacies or stores; the seller can recommend a suitable model. The product passport must be written in language, it must indicate that the device has passed clinical testing, and its accuracy corresponds to the reference mercury tonometer. Before purchasing, you need to ask to connect the device to the network and check its operation.

A Wi-Fi adapter allows the user to access the Internet without connecting wires. But before use, the device must be properly configured.

When choosing and purchasing a Wi-Fi adapter, you need to decide specifically for yourself why you will use it. For example, if you already have Wi-Fi Internet at home, but your desktop computer cannot enter the created network, because it simply does not see it. This problem can be solved by simply purchasing a standard Wi-Fi adapter with the function of receiving signals. In another case - when there is no Wi-Fi, but there is a computer with which you will distribute the Wi-Fi network. As mentioned above, in this case you will need to buy a Wi-Fi adapter that supports the signal distribution function.

Setting up a Wi-Fi adapter

After the Wi-Fi adapter is installed, the network must be configured. This process does not take very long. The most important thing is to follow the instructions exactly. The Wi-Fi adapter is configured slightly differently, depending on the operating system used. For example, the process of setting up an adapter on the Windows 7 operating system.

In the field where the network connection is provided, you need to find the item “Network and Sharing Center”. After the corresponding window appears, you need to find “Change adapter settings”. The Network Connections window will then open. In this folder you need to find the wireless connection and right-click to open the context menu and select “Properties”.

In the window that appears, you need to find and select the line “Internet Protocol TCP/IP v4” and click on “Properties”. Next, you need to check the box next to “Receive automatically” (on all values). Confirm this operation by clicking the “Ok” button. Then, if a connection has already been created on the router itself, you need to select the created connection in the all connections window and connect to the Wi-Fi network.

The setup and installation of the Wi-Fi network is complete, and users can easily use it.

WiFi or Wireless Fidelity is a technology for wireless data transmission over a special Wireless LAN channel. The WiFi network is half-duplex - this is due to the technology itself.

This feature means that only one device can operate on one frequency, acting as an access point. The access point can be either a computer with a Wi-Fi transmitter or specialized devices - routers that support the WiFi wireless protocol.

There are two ways to build a network using the Wi-Fi wireless protocol.

Setting up Wifi at home and connecting a laptop through it

Let's consider the option of a Wifi wireless network using a Router, when you already have a computer connected to the network (Internet) via a wired network and you also need to connect your laptop via WiFi.

This option is relevant, for example, if you have Internet from an Internet provider (say, Akado) for one computer, running over a wire. And you intend to connect the laptop to the same existing network, but via Wifi, in order to access the Internet from it and be able to move it around the apartment wirelessly.

And also, if independent Internet access on each computer is important to you. (You can turn off the computer and go to work on a laptop with the Internet in another room or in the kitchen).

To make this possible, you need to understand the scheme, read the article, following the instructions.

Scheme 1. Combining a Wifi router, computer and laptop:

What needs to be done to turn on the Router - step by step

If you are satisfied with the cable connection of the first computer (1) to the network and you do not plan to change it to Wifi, and Wifi is only needed for the second laptop computer (2), then you need to purchase a Wireless Router.

Such a wireless router has a wired connection option - UTP (LAN) connector(s), a WAN (“input”) connector, and an antenna for wireless contacts.

Let's look at the example of the ASUS WL-530gV2 Pocket Router (802.11g, 1xWAN+4xUTP) router operating according to this connection scheme. Which cost in Moscow in 2009 less than $100.

You can use, for example, a DLINK Router. The instructions are the same, with the difference that the WAN connector on it is labeled “Internet”.

Router ASUS WL-530gV2 (Pocket router)

In addition to the router, you also need an additional UTP-5 category cable, 1 m long (a regular cable for a computer network with connectors).

How to connect a router

The router must be connected to the gap between the modem that “gives” you the Internet from the provider and the computer (1).

To do this you need:

Turn off the power to the computer and modem. Place the router unconnected next to the modem.

Pull out the cable (UTP-5 type) coming from the modem from the computer’s network card (1) and connect it to the “WAN” input of the Router. For this model of router it is located on the side.

The router is now connected to the Internet. We need to distribute it.

We connect the computer (1) to the Router using the purchased additional UTP-5 cable:

One end goes into the computer’s network card, the other end goes into the LAN1 connector of the router.

We connect the router to power via its own power supply (must be included with it).

The router is connected.

Now you can turn on the power to your computer, modem, router.

Setting up a computer (1) to access the Internet via a Router via wire

Setting up a computer is essentially reduced to zero. If the Router has DHCP (a service for allocating IP and connection parameters for connected machines), just connect the PC connector to it and the computer will automatically receive an IP address from it.

The only thing is that if a specific IP address was set in the properties of the network adapter on the PC, then it must be reset to “Obtain an IP address automatically”.

IN Windows 7 this is done in:

« Control Panel\Network and Internet\Network Connections»

Go to: Start, Control Panel, Network and Internet, then:

View network status and tasks -> Change adapter settings.

Select your network adapter (where you connected the router), right-click - Properties, TCP / IP (IPv 4) - General.

Check “Obtain an IP address automatically” and “Obtain a DNS server address automatically.”

Click “OK”, “OK” again.

On Windows XP:

Start, Control Panel, Network Connections – select your adapter (“Local Area Connection”) – Internet Protocol (TCP/IP) – then everything is the same as in Windows 7.

Please note that the computer will “receive” the Internet only if the router is configured correctly and rebooted.

Setting up a Laptop (2) for Internet access

Go to “Network Connections” of your laptop in the same way as you entered when Setting up your computer (1), in accordance with the operating system already on the laptop.

Look for "wireless network connection".

Select your wireless network, named as indicated in the Router. Let's say mynet.

Click “Connect”. If the key was not installed when setting up the router (which is not recommended), then the Internet will connect immediately. Or, a window will appear asking you to enter the “Network Key”.

All. If the router is configured correctly, the Internet should already be available in the laptop.

You can check its operation by going to some fairly reliable site, such as www.yandex.ru, www.google.com.

These entered settings will not need to be specified again after the next turn off/on of the Laptop. It will connect to the Internet itself.
