Wi-Fi overview

Wi-Fi is the name of the popular wireless networking technology that uses wireless live to provide wireless high-speed internet and network connections.
Wi-Fi is a common misconception that the term "small for wireless loyalty".
It is sometimes written as WiFi, but none of these has been officially approved by the Wi-Fi Alliance. Wi-Fi is used at the end of the word "wireless", but wireless is really very broad.

How Wi-Fi Networks Works.

  • The main requirement for Wi-Fi is that there is a device that can transmit like a wireless signal, router, phone or computer.
  • There is no physical wired connection between the sender and the receiver in the Wi-Fi network using Radio Frequency (RF) technology - a frequency within the electromagnetic spectrum connected to the radio wave propagation. When an RF flow is supplied in an antenna, an electromagnetic field is created which is then able to propagate through space.
  • In a typical home, the router transmits an Internet connection coming out of the network like ISP and transmits the service to nearby devices that can reach the wireless signal.
  • Another way to use Wi-Fi is to have a Wi-Fi hotspot so that a phone or computer can share its wireless or wired internet connection, how the router works.

Check your Internet speed.

  • You pay for MBPs (megabit) in a certain amount of upload and download speed per second; Checking your actual upload and download speed will give you an approximate idea
  • Many Internet service providers advertise the speed of "up" to a certain number, which means that top speed is not guaranteed.
  • Most of the time, the highest upload or download speed of your computer, if the actual speed is close to the advertised speed, then your ISP is not a problem

Is Wi-Fi Always Free?

  • For Wi-Fi to work, the device transmitting the signal was an internet connection, which is not free. For example, if you have internet in your house, then you are probably paying the fee.
  • If you use Wi-Fi so that your mobile, iPad and Smart TV can connect to the internet, then those devices do not have to pay for the internet, but the line at home still costs in spite of Wi-Fi. Is performed.

How to Set Up Your Home Wi-Fi Network 

Find the right place for your router.  

Its optimal placement is the main place for your home, in which there are no barriers due to wireless interference like windows, walls and even microwaves. 

Close the modem

Turn off cable or DSL modems from your internet service provider

Connect the router to the modem

Plug the Ethernet cable (usually provided by the router) in the WAN port of the router, and then the second part of the modem.

Connect your laptop or computer to a router.

Plug the other end to the router's LAN port (do any one) at the one end of another ethernet cable and the other ports in your laptop's ethernet port. Do not worry

Strengthen the modem, router and computer -

Turn them on in that order

Go to the management webpage for your router.

Open the browser and type the IP address of the router's admin page; This information is provided in your router documentation (this is usually something like 19268.1.1). There will also be login information

Change the default administrator password (and username if you want) for your router

This setting is usually found in a tab or section called Admin. Remember to use it

Add WPA2 security

This step is required You can find the settings in the Wireless Security section, you choose which type of encryption you use, and then enter at least 8 characters passphrase - the more complex the more characters and the passwords the better. WPA2 is the latest wireless encryption protocol, which is much safer than WEP, but you may need to use WPA or Mixed mode WPA / WPA2 if you have no device in your device. WPA-AES is the most robust encryption available today.

Change the wireless network name (SSID)

To make this easy, select a descriptive name for your SSID (service set identifier) in the Wireless Network Information section.

Optional: Change wireless channels.

If you are in an area with many other wireless networks, you can reduce the network of other networks by interfering with the use of your router's wireless channel. You can use a WiFi analyzer app for your mobile phone or just use trial and error (since it does not overlap using channels 1, 6 or 11).

Set up a wireless adapter on the computer

After the configuration settings on the router are saved, you can unplug the cable connecting your computer to the router. Then plug your USB or PC card wireless adapter into your laptop, if your computer already has a wireless adapter installed or built in, then your computer will automatically install drivers or if you use the setup CD with an adapter installed

Finally, connect to your new wireless network

Connect to a new network and set up on your computer and other wireless-enabled devices (step-by-step instructions are in our Wi-Fi connection tutorial).

Buy a new router.

  • As mentioned previously, there's only so much that you can do with old technology. If your router and/or modem is more than a few years old, buying a new one will almost certainly increase your Internet speed and reception.
