How Does a Wi-Fi Router Work

At an earlier time, many of us lived in a house with a single PC, where we only need a modem to connect to the internet. Technically, if you only want to connect one device, you can still use the modem only. However, for security reasons, it is best to use a Wi-Fi router even for only one device on your network.

But now that homes usually have more than one device, a router is important. You need a router to connect multiple devices to the Internet. If you are wondering to know how does a Wi-Fi Router Work? You are at the right place.

This article will inform you about how does a Wi-Fi Router Work, types of Wi-Fi router, and things to consider before buying a Wi-Fi router and more.

How does a Wi-Fi router work?

A Wi-Fi router connects the number of devices to a network without using wires from the computer to router. It allows users to connect to the internet quickly and easily, usually within 100 meters of the wireless signal. It does not only connect number of devices to the internet  but also help you to connect multiple devices with each other.

Without the internet, you can still build a local network for computers and other devices. This allows you to transfer and share files across specific devices within the network, including printers, scanners, and game consoles.

Please Note: Most of the modern modems are wireless and have a built-in router

What are the types of Wi-Fi router?

There are three main types of Wi-Fi router; single, dual and tri-band. The details of each are given below:

1. Single-band Wi-Fi router

Single band Wi-Fi router uses only one band; 2.4 GHz. More traffic in single-lane often results in slow speed. Its internet service is easily interrupted by the latest gadgets such as Bluetooth, camera, cell phone, television etc. It is good for the house with a single device. You can buy it for under $50.

2. Dual-band Wi-Fi router

It uses two bands; 2.4 GHz band and 5 GHz band. It is most useful for houses with 2-5 devices. It offers a faster and stable internet connection all over your home. It is not interrupted by any electronic device because of its separate network. It is considered dedicated networking for watching videos and playing games. Its price range is $100-$200.

3. Tri-band Wi-Fi router

It uses three bands; one 2.4 GHz band and two 5 GHz bands. It is best for home with more than 10 devices. It offers the highest speed, lowest interference, more bandwidth and wider coverage. Although, it is expenses with the price range of $300-$400. However, users say that the services worth the price.

Why you need a Wi-Fi Router?

The routers are very important when it comes to automating your home. Since a automated or smart home is also a local network of devices, without a router they cannot communicate with each other. Depending on the device, you may need an Internet connection if services are hosted by the cloud. But in the end, the router connects these data packages.

Moreover, Wi-Fi router is used to create local network. A router is a central route for your home network. It connects directly to your network cable, or via modem. All internal and outgoing traffic is transferred to the router. The physical position of the router and the direction of its antenna play an important role in getting the best coverage.

4  Things to Consider Before Buying Wi-Fi Router

You may have used a Wi-Fi network in a shopping mall or somewhere else but never set it up yourself. So, what do you need to know if you are getting a Wi-Fi router at home. The following points you should keep in your mind.

1. What type of Wi-Fi Router do you need?

Depending on your Internet service provider (ISP), you may need to purchase a router, a different router and modem, or a modem. Almost all ISPs use DSL or fiber for their service, which requires modem switching. Most modern routers have built-in modems, so you only need one device.

However, it is worth checking with your ISP as some require the use of a related modem.

Before jumping in, you should be aware of which router features are most important to you. Your needs will vary if you intend to use your Wi-Fi network for online games or activity.

2. How to Protect and Configure a Wi-Fi Network?

Once you have registered with the ISP and purchased your router, you will need to set up your home network. While this will vary with the device, there are general considerations for new routers.

Most routers have a well-known username and password. You must change your Wi-Fi control password because unchanged login details are easy to hack.

When connecting devices to Wi-Fi, you will need to enter a password to access the network. This password is different from your router and you can always find it on the label on the router itself. Wi-Fi password ensures that people don’t connect without permission.

You may find that after setting up your network, it seems to slow down more than you expected. Check out our slow Wi-Fi repair guide if that’s the case. If children are using your Wi-Fi network, it may be best to set parental controls on your router.

Wi-Fi security

Choose a router having built-in security features, like automatic firmware updates and device quarantine. It will protect your network from cybercriminals.

Wi-Fi coverage

It depends upon the size of your home and barriers such as thick walls, mirrors, fireplaces and other objects that block internet signals. Select the router that can provide network coverage to every corner of your home.

Wi-Fi controls

Latest routers are user friendly and easy to install. The option of a mobile app helps you to control user time, manage the guest network and parental control.
