How does the Wi-Fi network work?
Perhaps it is not too late when we have moved away from the exclusive access to Wi-Fi in airports, coffee shops or special hotels, and today Wi-Fi networks or the 802.11 network, It exists in almost every home and company. Even in many cities of the world, they use this technology to provide free or low-cost Internet access to city residents. In this regard, one of the interesting questions about the Wi-Fi network is How exactly does WiFi work?modem router + ADSL2 TP-Link model TD-W8961N_V4 820,800 Tomans Modem TD-W9960-v1.20 TD-W9960-v1.20 VDSL/ADSL router 944,700 Tomans Buy all kinds of modems and routers from SafirSoft View all
What exactly is a WiFi network and how does it work?network or Wi-Fi is a system that uses radio waves, just like cell phones, televisions, and radios. In fact, it is interesting to know that communication through a wireless network is very similar to two-way radio communication! In this section, we examine everything that happens during your access to the global Internet:
What exactly is WiFi and how does it work? ?
The process can also work in reverse, so that the router receives information from the Internet and translates it into radio signals and sends it to the wireless adapter in the computer. Radios used for Wi-Fi communication can send and receive radio waves as zeros and ones converted to radio waves or vice versa; But you need to know that these types of radios have some basic differences with normal radios (in mobile phones and other devices). GHz is sent; This frequency is significantly higher than the frequencies used in cell phones, pocket radios, and televisions. In general, sending waves at a higher frequency allows the signal to carry more data.

In general, what The Wi-Fi standard we know and use uses the 802.11 network standards that have evolved over decades. garlic You can follow the evolution of this network in the rest of this article. 802.11b (introduced in 1999) is the slowest and least expensive network standard, which according to Its costs became popular for a while, but this type of network is less common today as the cost of other standard and faster communications drops. 802.11b is capable of transmitting radio spectrum in the 2.4 GHz frequency band and at the same time can support up to 11 megabits of data per second.
Other 802.11 standards govern specific applications of wireless networks, such as wide area networks (WANs) inside vehicles.
Hotspot, my internet isn't working!
A Wi-Fi hotspot is an area with an accessible wireless network, this term often refers to wireless networks in public areas such as Airport and coffee shops are used. As you have probably experienced, using a smartphone you can create a hotspot and create an environment with internet available to everyone.In general, sending waves with a higher frequency allows the signal to carry more data. to carry
Most new laptops, many modern computers (PCs) and almost all smartphones have a built-in wireless transmitter. At the same time, if your PC is not already equipped with this part, you can buy a wireless or wireless adapter and connect it to the computer's card slot or USB port. Many of these adapters can use more than one standard 802.11 network.
When a wireless adapter and its drivers are installed on a device such as a home computer, your computer should automatically detect the available networks. finds This means that when you turn on your computer at a point equipped with a WiFi connection, the device will show you the available networks. It should be noted that if you have an old computer, you may need to use a suitable software to identify and connect to the Wi-Fi network.

Principles and how to build and set up a wireless internal network h2>
If you have several models of computers and smartphones in your home, you can create a network with a wireless access point in the environment. Create your own. In order to set up an internal network at home, you need the following equipment:
- A port to connect to a cable or DSL modem
- A router
- A hub Ethernet
- Dongle or network card
- Wireless access point
In general, buying a wireless router gives you this It allows you to use wireless signals or Ethernet cables to connect your computers and devices to each other and to the Internet. In this regard, it is necessary to know that most routers provide coverage of about 100 feet (30.5 meters) in all directions. On the other hand, walls and doors can block wireless signals, so if your house is very large, you can buy an inexpensive amplifier to increase the range of your router. Like wireless adapters, many routers on the market can use more than one standard 802.11 network. Typically, 802.11n routers are a little cheaper than other models, but since their standard is usually older than 802.11ac or 802.11ax, they are also slower.

Also, you should Also buy a network card or dongle. Any device you connect to a WLAN must have a wireless network card. Wireless network cards for desktop computers may come in the form of network cards with antennas or USB adapters.
Wireless network configuration
The wireless router can support a WLAN and by using it in the network, you will be able to create a new wireless network or rebuild the current network. By installing the router to the electricity and then to the computer, you can enter the necessary information in the user panel and then assign a password for the wireless network so that no user can access your Internet. Make sure that all wireless devices and routers must have the same SSID. After applying the relevant settings, press the button to save the settings and restart the router so that the changes are applied.It is necessary to know that Wi-Fi signals propagate from top to bottom, so the higher the device is, the better the antenna condition is naturally. will be.
After applying the necessary adjustments to the rotor, it's time to find the center of the house! After identifying the central location in the house, you should place the router as high as possible. In general, you need to know that Wi-Fi signals propagate from top to bottom, so the higher the device is, the better the antenna will be. configure the You need to know that this process is not particularly complicated and can be done with the least possible effort, because Windows itself implements everything that is needed. In this regard, wireless network cards are set by default to work in "infrastructure" mode, which means that they automatically detect the WLAN channel number and connect to it.TP-Link TD-W8961N_V4 +ADSL2 Modem Router 820,800 Tomans TP-Link VDSL/ADSL Modem Router Model TD-W9960-v1.20 944,700 Tomans Buy Modems and Routers From SafirSoft View All
