What requirements you need to know before buying a Wi-Fi router

At present, the Internet has become a basic human right. In the past, most users used the Internet from desktop computers. Now the use of a laptop computer from the desktop is gradually increasing. 

Nowadays, the number of internet users on mobile phones is increasing rapidly. With Internet TV, smart home devices are connected to each other through wireless internet. And the device that is essential for this wireless internet is the Wi-Fi router. You need a router to use an internet connection at home or in the office. 

There are also different quality routers of different prices in the market. But who needs to know what kind of router.


Why Wi-Fi Router

If you use the internet on just one mobile phone or device, you can turn on the internet package as needed. But if the Internet has to be used on more than one device, it is impossible to use it with one package. First of all, there is no opportunity to share an internet connection connected to the mobile phone or desktop with other devices.

Another reason is that mobile phone internet packages are relatively expensive. It is possible to use packages of several times higher speeds and higher data volume on the same cost broadband internet or WiMAX connection.


Buy a router by understanding the type of work.

The way to use multiple users from an Internet connection and multiple mobile phones and computers is to connect a Wi-Fi router to that connection. 

There are different types of routers in the market with different features. You have to choose your router according to the type of work. A state-of-the-art router with very high capacity is not something you have to buy. Rather, the choice should be based on what kind of work the router will be used for.


Keep in mind the band of the router

There are single, dual, and tri-band routers. Simply put, there are a few bands that can be found on the router. The use of single-band routers is high. It has a network of 2.4 GHz. The dual-band has a network of 2.4 GHz as well as 5 GHz. The 5 GHz network can exchange data at high speeds. But this high speed makes it difficult to get the signal across walls or large objects.

Tri-band routers have a 2.4 GHz and two 5 GHz networks. The purpose of having multiple networks is that high-speed devices and relatively low-speed devices can exchange information without any problems.

If you are thinking about the wireless network's speed and want to use more than 10 devices from the router at the same time, you can only buy a tri-band router. A 2.4 GHz router is sufficient for general use in-home or small office.


Know the wireless standard (it is better not to go below AC1200)

There are several wireless standards, such as the AC1200, AC1900, or even the AC5400. If you see that the router is AC750, AC900, or anything less than AC1200, it means that the router is old technology;

 the old technology router is a modern smart home where you need speed, stability, and security to stay connected to many devices.


MU-MIMO or 802.11ac Wave 2 support

MU-MIMO, Multi-User MIMO, or Multi-User Multiple Input Multiple Output can transmit multiple wireless clients at once or transfer data to a network client.


Processor (single-core 800MHz) and RAM (better not to go below 128MB)

Check whether your router is single-core or dual-core, or quad-core. Naturally, dual-core and quad-core routers can keep more devices connected than a single core.

How fast your router will work depends on the processor as well as the RAM. If money is not a problem, take 256MB or more of RAM.


Cloud Support App

You can also control the router from outside the home.


USB connection (better if USB 3.0)

You can easily connect a USB storage device to the router.


Advanced features (e.g., QoS, Smart Connect, and Beamforming)

QoS or Quality of Service is a tool that allows you to set the speed manually on different devices.

Smart Connect is a tool that uses the same network name in both the 2.5GHz band and the 5GHz band, without having to use different network names in the 2.5GHz band and the 5GHz band. Smart Connect connects by providing bands according to the capabilities of each device according to device.

Beamforming (included in the 802.11ac standard) is a tool that allows the router's wireless signal to focus on the area of ​​the device without focusing in all directions.


VPN support

Suppose your home is in Mirpur. You have hosted a file server on a private IP in your home. Now you want your server to be accessed from your friend Gulshan. 

Usually, this is not possible. But it can do this with a VPN supported router.


Portability

Some routers can use mobile SIM. The device has a battery that can be used to charge a router outside the home.

What requirements you need to know when using a router

When enabling Wi-Fi on that router, the router's name is mentioned as the default network, and the password is also written on a sticker at the bottom of the router. If necessary, the method can be known by looking at the usage instructions.

Change the name of the wireless network by connecting the router for the first time.

The name of the wireless network should be changed by connecting the router for the first time. 

Network passwords should be used as well. Anyone can join the router if no password is given. Such a condition should never be kept for personal use.


If you forget the password of the router, it can be reset or reset. Usually, This can be done by pressing a button next to the router.

The router should usually be placed in the middle of the house. This allows you to easily connect to the router's Wi-Fi connection from other homes.

Choose a router depending on how large you want to connect to Wi-Fi.

Multiple local area network connections are connected to the router at the same time. If you want to add more LAN connections, you should look into buying a router.
