What does a wifi adapter consist of?

After that you must also solder the antenna to outputs ANT and GND, it is highly recommended to install LED type AL 307 on the pin 3.3 V cathode and on the pin USB +5 V anode (otherwise you should perform soldering by hinged mounting of DCDC converter). Finally assemble everything and place it in the case from under the flash drive, if necessary fix the parts with hot melt adhesive.

Wi-Fi adapter for computer: what is this "beast" and how to work with it?

Wi-Fi adapter for computer – a device designed to receive and distribute a wireless network. Its use compensates for the disadvantage of modern PCs or laptops that do not have a built-in device, or saves when the Wi-Fi module fails. Below we will consider the rules for selecting, installing and configuring this product, highlighting the main problems and ways to solve them.

What is a Wi-Fi adapter for a computer?

Wi-Fi module for PC is a small product for data exchange, working in the broadband Wi-Fi range. The adapter receives a data packet using a special antenna. The information is digitized inside the chip with the software installed on it. For the operation of the device it is necessary to install the software, which provides control and normal functioning of the product.

Wi-Fi adapter for computer is designed to receive-transfer data in a situation where a computer, laptop or other device is not equipped with a built-in module. The product is capable of receiving and transmitting information, which allows you to simultaneously receive and distribute the Internet from one computer to other PCs. The device has a number of limitations on the data transfer speed, which rarely exceeds 3-5 Mbps. But it is enough for full-fledged surfing, downloading and watching videos on the web.

Wi-Fi adapter for computer is used to solve such problems:

• connection to an already installed and connected router, modem;
• organization of Wi-Fi connection for connecting other equipment;
• arrangement of a wireless network in case of failure of the built-in adapter;
• solving additional tasks, for example, analysis of the network.

After installing and configuring the Wi-Fi transmitter for your computer, you can work on the Internet as usual.

Can I use my router as an adapter?

Today's routers are multi-functional devices that can handle tasks of varying complexity. One option is to receive rather than distribute the Internet. So the answer to the question of whether a router can work as a WiFi adapter is yes. But each model has its own nuances.

This function is useful if for some reason the adapter on a PC, laptop or other device does not work, and you have another router in stock. It can be used as a receiver and thus save money on the purchase. The question is whether it is easy to set up the desired mode, test its operation and cope with possible difficulties (if any).

How to make an adapter from a WiFi router?

Note that there is no single scheme that allows you to use a router as a Wi-Fi adapter. Each individual model has its own settings and parameters.

TP-Link

TP-Link routers are not able to work in the repeater mode, which creates a number of difficulties when setting up. But that does not mean that they cannot be used as a receiver. To use a WiFi router instead of an adapter, start by changing the Wi-Fi channel on your main router. Keep in mind that the signal source will be used as a bridge, which requires proper configuration. In other words, it must distribute wireless Internet.

• Log in to the sharing device and set a static channel for WiFi. Approaches may vary depending on the manufacturer. If the main router is also Tp-Link, go into the setup panel, go to Wireless and in the Channel field specify a static channel. This can be a one or a six. After that, save and wait for a reboot.

• To turn your new router into a Wi-Fi receiver, go into its settings and change its IP address. If you use the router as an adapter, there should not be a match. Otherwise, address conflicts and malfunctions will occur. To make changes, go to Network and then LAN. There find the IP Address section, which will be different from the main device information. For example, you can use IP 192.168.1.2. After saving, check if the information is still there.

• Enter the Wireless section. In the Network Name field, enter the name of another network, and in the Channel field, specify the channel set in the settings of the base router. Then check the Enable WDS Bridging box and click Survey. Determine the network of interest that you will use and click Connect.

What is it for?

A network adapter for Wifi for your laptop is needed to connect your laptop to a WiFi network and surf the Internet. The equipment provides reception-transmission of information by means of broadband radio communication and works within certain frequencies. The laptop WiFi module converts electronic information into radio waves and transmits them through the air. In addition, the unit receives such waves with subsequent conversion into a digital signal. Structurally, adapters consist of the following elements:

To work properly, the WiFi module for your laptop needs a special driver software to be installed.

How to Connect a Laptop Wi-Fi Module to a Computer

Ensuring the compatibility of the portable module with the PC motherboard is done with the help of a physical adapter, which is a simple adapter that reassigns the pins needed for the device to work. The only electronic "wrapping" designed to provide power and located on the front side of the PCB is a pair of electrolytic capacitors and a voltage regulator (3.3 V). Almost always two antennas are included. The sequence of steps when connecting a notebook WiFi miniPCIe board to a PC PCIe slot is as follows:

• disconnect the WiFi module from the laptop's motherboard;
• Insert the module into the miniPCIe slot of the adapter, securing it with screws of the appropriate size;
• use the connectors at the ends of the coaxial cables to connect the antennas and the WiFi module;
• insert the WiFi-adapter from the laptop to the PC into the PCIe slot of the motherboard;
• Configure the device in the operating system by installing the appropriate driver-controller;
• Set up the connection by entering the name of home or office wi-fi network (SSID) and password, then make connection.

Useful to know! If the brand of WiFi-adapter is unknown, it is always possible to find the driver for it by means of PCI/VEN-ID. In Windows it is necessary to right click on "My Computer", choose "Properties" and "Device Manager", find unknown Wireless device, open its properties and choose "Device ID" from the pull-down menu in the "Information" tab. Then enter the copied ID into any search engine, it will give a number of queries, from which you can choose the appropriate one. On Linux, the response from the PCI installed hardware, containing the device model information, is obtained with the lspci utility from the pciutils package. To determine the WiFi module you must type the command "lspci | grep wireless". If you know the model, you can easily find the necessary drivers on the manufacturer's website or on third-party software vendors.

WiFi adapter on DVB T2 digital set-top boxes and satellite receivers

You can understand why you need a Wi-Fi adapter on set-top boxes and receivers by taking advantage of all sorts of Smart features. Wi-Fi adapter is needed for such purposes:

For the various functions to work, you need an Internet connection.

Please note! Any STBs, tuners, usually have the ability to connect to the Internet via LAN input, that is, by cable. But there are models that support Wi-Fi adapters that connect via USB. To do this, just connect the device to the appropriate jack on the set-top box and set the desired settings.

But to use this device on set-top boxes, receivers, tuners, you need to consider a number of basic points:

• First, before you buy an adapter, you need to make sure that the set-top box or receiver actually supports the ability to connect to the Internet. Some of them have USB-connectors designed to connect only the drives. To do this, you can read the characteristics of the device, study the menu or reviews on the Internet;
• For a particular type of set-top box, you need to select a type of adapter as well. They can work only with certain types, this should also be taken into account before buying. Sometimes it turns out that the set-top box simply doesn't see the connected adapter. Devices with the same chipset can work together. And they do not necessarily have to be from the same manufacturer;
• If you intend to place the set-top box far from the router, in a place where the signal is not too strong, it is better to buy an adapter with an external antenna.

How to choose

An adapter is a device that has characteristics that must be taken into account to provide the best signal. They are indicated on the device itself or in the manual. Consider what to pay attention to when buying:

1. Communication standard. It determines the speed at which the information is transmitted. Buy a device with speeds up to three hundred megabits per second with support for the modern 802.11ac standard. If the router is 802.11ac and the adapter is 802.11n, there will be connectivity to the network, but the speed will be limited to 802.11n;
2. Frequency range: 2.4 or 5 gigahertz;
3. Power is measured in dBM decibels. Responsible for connection stability. Buy at least twenty;
4. Protect your data from hacking. The reliable protocol is WPA/WPA2-PSK;
5. Range. For use in an apartment, choose models designed for a distance of five meters. This will ensure full coverage of the apartment and the connection will be stable. Orient this figure depending on where the device will be used. In an open area or indoors.

For example, if your home router does not support 802.11ac, do not buy a device that supports five gigahertz. When buying, do not look at the manufacturer, but at the features of the device and its cost. Look for information in online stores, read product reviews.
