Wi-Fi Router Buying Guide

You can very well ask, “What is there to see in a Wi-Fi router?” You can buy any router and set the ball rolling. No, it is not the case.

Do you know that various factors like the size of your home, the thickness of your walls, your neighbour’s Wi-Fi signal, your microwave, and other appliances can affect the quality of your Wi-Fi signal?

If I say that a wireless router has features like ASDL, Fiber Internet, single band, dual band, 2.4 GHz, 5 GHz, and use terms like IEEE 802.11n and IEEE 802.11ac, and so on, you will end up confused.

Through this buying guide, we shall explore these features and make things simple for you. Before commencing with the buying guide, we would like to make one thing very clear. “The most expensive router is not necessarily the best one for your home.”

First things first, “What is a Wi-Fi Router?”

In simple terms, a Wi-Fi router is a device that connects various wireless devices at your home such as your smartphone, laptop, tablets, printers, TVs, Set Top box, USB dongle, and so on to the internet. It enables these devices to communicate with each other.

What does IEEE stand for?

Institute of Electrical and Electronics Engineers (IEEE) defines the standards for electronics and electrical instruments. IEEE 802.11 specifies wireless devices communications standards.

Difference between IEEE 802.11n and IEEE 802.11ac

You will encounter these terms when you purchase your wireless router. Know the difference between these two terms.

IEEE 802.11n

  • Widely used standard in the current generation of Wi-Fi routers
  • Provides better speed as compared to the IEEE 802.1 a, b, or g standards
  • Compatible with devices built based on the older standards
  • The maximum speed of such routers is theoretically 600 Mbps and practically 300 Mbps.

IEEE 802.11ac

  • Next-gen IEEE standard
  • Practically seven times faster than the IEEE 802.11n standards
  • It can theoretically produce a maximum speed of 7Gbps and virtually around 2.2Gbps
  • Naturally, these routers are more expensive than the IEEE 802.11n
  • Explain single-band and dual-band Wi-Fi routers

Generally, Wi-Fi routers operate in two distinct radio frequency bands, 2.4 GHz and 5 GHz. As the name suggests, the routers that can use both these frequency bands to communicate with the respective devices are the dual-band routers whereas the single-band routers are those that use either the 2.4 GHz or the 5 GHz frequency band for communication.

What is the difference between the 2.4 GHz and 5 GHz bands?

The principal distinction between the two is in the signal coverage and bandwidth speed. The 5 GHz band can transmit data at faster speeds but have a shorter coverage area. Alternatively, the 2.4 GHz band can cover a larger area but results in slower data transmission.

Tri Band WiFi as Fast As Possible

Let us now understand the significance of the two frequency bands. If you have an iPad at home, you will notice that it can work at both the speeds. The regular smartphones and laptops do not operate in the 5 GHz band.

Both the frequency bands have their advantages and demerits. The signal coverage in the 2.4 GHz band can easily penetrate the walls and floors of your house. Hence, you will be able to use the Wi-Fi internet from your router while sitting inside your neighbour’s apartment.

At the same time, the lower frequency band cannot carry more data. It affects the downloading and uploading speed.

The 5 GHz band allows for faster downloading and uploading of data, but it cannot penetrate the walls of your house. It explains why your iPad slows down when you shift to a room different from where you have the Wi-Fi router. The 5 GHz band allows you to download and watch movies faster than the 2.4 GHz frequency band.

No, you understand that if you face slow downloading speeds, you should switch over to the 5 GHz wireless router.

Other factors that affect your Wi-Fi speed

Noise and interference can affect your Wi-Fi speed. When we say ‘Noise’, we do not mean the noise that we humans make, but the signals from your wireless devices like your smartphones and microwave ovens, and so on.

The Wi-Fi signal from your neighbour’s house can also affect your router’s performance.

Most of the devices in the home operate on the 2.4 GHz frequency. Fewer devices use the 5 GHz. Therefore, the 5 GHz frequency band is less crowded in comparison.

The 5 GHz band has 23 overlapping channels thereby allowing different devices to run simultaneously on this frequency. The 2.4 GHz has eleven channels of which only three are non-overlapping.

Channel width – How do you adjust it to get better coverage?

Compare the channel width with a road. The wider the road, the easier it is to travel on it. Similarly, bigger the channel width, the more data it can carry. The 2.4 GHz band has 11 channels, each of which has a width of 20 MHz.

The 5 GHz has 23 channels with a channel having a maximum width of 160 MHz. As fewer devices use the 5 GHz band, there is less congestion. It explains why the 5 GHz can accommodate higher speeds.

The tri-band Wi-Fi router

As the name suggests, this Wi-Fi router uses three frequency bands to communicate with devices. These are one 2.4 GHz band and two 5 GHz bands.

Compared to the standard single or dual-band routers, the tri-band wireless routers can provide higher speed and bandwidth. Hence, they are expensive.

The Concept of Mesh Wi-Fi system

The Mesh Wi-Fi system can cover more than 5000 sqft of area. It is a set of Wi-Fi router nodes organised in a mesh topology. In common parlance, it consists of one main hardware unit connected to an internet cable.

What is Mesh Wi-Fi?

There are multiple Wi-Fi nodes placed at different locations in the home. It becomes useful to communicate with various smart devices in your home. They are usually tri-band routers. Some of the primary manufacturers of routers are Asus, D-Link, Netgear, Google, and Samsung.

The role of the antennas in the Wi-Fi router

The antennas can improve the signal coverage of the Wi-Fi router. Usually, there are two types of antennas, Directional and Omni.

The primary difference is that the directional antenna can transmit and receive data in one direction only whereas the Omni antennas receive and transmit data in a circular pattern. Usually, you find the Omni antennas in your home Wi-Fi systems.

The significance of the terms, 2 dBi, 5 dBi, 7 dBi, and 15 dBi Omni antennas

What does the term dBi refer to? It refers to the power of the antenna measured in Decibels related to the Isotropic radiator at radio frequency. We need not go too deep into the technical aspects.

While purchasing the Wi-Fi router, we should note that the signal coverage and reachability of the router will be better for a higher level of dBi. You will also notice that some routers have more than one antenna. The more the antennas, the better is the signal coverage.

The Positioning of the antenna

Do you remember that the olden-day television sets had antennas on the terrace? You need to position them in such a way that they face the direction of the television tower in your city. It improved the receiving signal.

Similarly, the Wi-Fi router antennas are crucial. You should position them appropriately. If you live in a flat or an apartment, you should place the antenna upright.

If you live in a duplex house, it is advisable to keep one antenna upright, and the other one parallel to the floor. Under such circumstances, both the floors experience better signal coverage.

The Modem

You must have heard the word, ‘Modem.’ The modem is an acronym for Modulator-Demodulator. It is a hardware device that converts the analogue signal from the telephone or the cable wire to the digital signals that your computers can understand.

Similarly, it converts the digital signal into the analogue form while transmitting the signals over the cable/telephone wire.

Types of modems

You have two types of modems, the DSL and the ADSL modems.

Cable Internet vs. DSL Internet

DSL stands for Digital Subscriber Line and ASDL signifies Asymmetric Digital Subscriber Line. The difference between the two is that ASDL is an advanced version of DSL technology. It provides more bandwidth and faster data transmission than the traditional voice-band modem.

If you have the ADSL ISP, you need to have an ADSL modem. Network service providers like BSNL, Airtel, Reliance Broadband, and Tata still use the ASDL technology.

Fiber Internet

We have seen that the traditional ISPs come with ASDL telephone lines. There is a limitation of bandwidth and speed in an ASDL line. The Fiber Internet is an advanced technology that provides ultra-high bandwidth and ultra-high speed internet.

It uses Fiber Optics technology for transmitting data signals as opposed to the electromagnetic current or electrons to transmit data through copper wires in the case of ASDL.

Multinational companies, banks, Indian Railways, Google, and many TV channel operators use this technology. The Fiber Internet is also available for home internet through companies like ACT and more recently, Airtel as compared to the ASDL lines the Fibernet is expensive.

Wi-Fi Security

When you transmit data over a wireless medium, anybody can intercept it and steal the data provided they have the devices to capture the signals. You can prevent such unauthorised capturing of data by encrypting the data before transmitting it. There are various encryption security standards such as WEP, WPA, and WPA-2.

Software features in a Wi-Fi router


How will the router identify the device to which it is communicating? It uses a unique ID known as the Internet Protocol Address, also commonly known as the IP address. Every device, including the router, will have an IP address.

The DHCP (Device Host Configuration Protocol) is the software feature that enables the private IP address to each device in the network. If the DHCP feature is not present, the user has to manually configure the IP address of every device that wants to join the network.


The DHCP enables the private IP address to allow the router to communicate with each connected device. However, the devices will not be able to communicate with external servers like Google or Yahoo using the private IP address.

You will require a public IP address to communicate with the internet servers. The NAT (Network Address Translation) feature, when turned on, will change the source IP address of all data packets coming from the internal network towards the internet, to the public internet-visible IP address. Similar is the case with incoming data.

Different types of ports in a Wi-Fi router

Usually, you will find the following ports in your Wi-Fi routers. Note that all routers need not have all the mentioned ports.

RJ-11 Port

The RJ-11 port is useful for connecting the input telephone cables from BSNL, Airtel, and so on for the ASDL Broadband connection. These are small ports with the input connection comprising of two wires.

RJ-45 Port

When you use the Fiber Internet connections like ACT, Airtel Fibernet, Hathaway, and so on, you will need a bigger port known as the RJ-45 port. This port accommodates the input connections comprising of eight wires.

USB Port

The USB port does not require any explanation. You can use the USB Dongle or the Data Cards from telephony companies like Airtel, Reliance, Tata Photon, and so on.

SIM Card Slot

Nowadays, you get Wi-Fi routers having SIM Card Slots where you can insert the SIM cards from ISPs like Airtel, Vodafone, and Reliance, and so on to access 3G and 4G internet connection. The modern-day routers like iBall and Connectwide have these slots.


Tips for selecting the right Wi-Fi router for your home

We have seen the Buying guide in detail that explains each part of the Wi-Fi router thereby making it easy for you to understand the technical terms while purchasing the right one for your home. These following tips will make it easier for you.

1. Check out the connection you have. If you have the standard BSNL or the Airtel connection, you can go for the ASDL routers. If you plan to have the ACT or the Airtel Fiber Internet, you need to opt for the Wi-Fi routers having the RJ-45 ports.

2. Choose the IEEE 802.11ac standard as it is the latest one. This router will accommodate both the 2.4 GHz and 5 GHz frequency bands. These routers have the backward compatibility feature as well.

3. Always go for the dual-band wireless routers as your current generation laptops and iPads can use the 5 GHz frequency band for higher speed.

4. Opt for the routers that have USB ports. It can prove useful if you experience disconnection problems of the Fibernet or internet. You can plug in your data card and use the Wi-Fi router.

5. It is advisable to opt for Wi-Fi routers with multiple antennas as they can enhance the overall range of your Wi-Fi signals.

Frequently Asked Questions

1. What is a 4X4 MIMO Wi-Fi router?

Wi-Fi antenna signal streams cannot simultaneously receive and transmit signals. MIMO denotes Multiple Input and Multiple Output. The 4X4 MIMO Wi-Fi router will have four transmitting antennas and four receiving antennas.
Similarly, you have the 3X3, 2X2, and 1X1 MIMO Wi-Fi routers. The routers supporting IEEE 802.11ac standard must support the MIMO feature.

2. What are SU MIMO and MU MIMO routers?

SU MIMO denotes Single User MIMO thereby implying that it uses all its antennas and spatial streams to communicate with a single device in the network at any given point in time. MU MIMO stands for Multiple User MIMO, a self-explanatory term.

The advantage of the SU MIMO is that it can provide higher speeds and minimises data loss because many antennas communicate with a single device. In the case of MU MIMO, the device should support MU MIMO for the router to interact with it.

It is a better feature because the router can serve more than one device at a time. For example, three people can use the Wi-Fi for three different purposes at the same time in the house.

3. What is an ADSL Modem router?

A Wi-Fi router with an in-built ASDL modem in it is an ASDL Modem Router. Note that all Wi-Fi routers have ASDL ports. You should check out for the same when you buy the router as you would not be able to connect the ASDL phone line otherwise.

4. Does a Fiber Internet connection require a different type of router?

Usually, you do not need a special type of router for a Fiber Internet connection. Ensure that your router has the RJ-45 Ethernet ports also known as WAN ports in your routers. Most of the wireless routers have them.

5. What is the use of a Wi-Fi extender?

Sometimes, you find that you do not get the signal in rooms that are about 25 to 30 feet away from where you have placed the router. There could be many walls in between that could block the signals.

Under such circumstances, you can use a Wi-Fi extender. It is a device that extends the range of your Wi-Fi signal. You place the extender about 15 to 20 feet from the router to retransmit the signal more powerfully.

6. What do WEP, WPA, and WPA-2 stand for?

All these three terms refer to encryption security standards. WEP denotes Wired Equivalent Piracy. WPA signifies Wi-Fi Protected Areas, and WPA-2 is an advanced version of WPA. Naturally, the WPA-2 is the most potent and secure of the three.

7. Explain the distinction between Megabytes/Gigabytes and Megabits/Gigabits

Any student having an elementary knowledge of computers will tell that 1 byte is equal to 8 bits, 1 MB = 1024 KB, and 1TB = 1024 Gigabytes, and so on.

Therefore, when you have a 300 Mbps (Megabits per second) router, it will transmit 37.5 MB of data in a second and not 300 MB size file in a second. Similarly, an 8 Gigabits per sec (Gbps) will transmit 1GB (Gigabytes) of data per second and not 8GB.

8. What is the Firewall feature in a Wi-Fi router?

The Firewall is a parental control feature available in Wi-Fi routers to restrict the internet usage of children. It can prevent unauthorised devices from communicating with the router. It is a rule-based filter.

These rules tell the Wi-Fi router which of the devices does not have permission to communicate with it. The rules are based on the IP address or the MAC address (Media Access Control).

9. Explain the concept of QoS and how does it work

QoS denotes Quality of Service. It is a unique feature available on Wi-Fi routers that tells the router how to handle various classes of traffic. The advantage is that the router will never drop high-priority traffic even during load congestion whereas it will do so with the low-priority ones.

This example can explain the QoS feature better.

You have to use the internet for doing some critical office work. Children in the house would like to play games or watch movies using the same internet connection. Now, the high-bandwidth game traffic can affect the quality of the low-bandwidth VPN connection that you use for doing your work. You can resolve the matter in two ways.

Ask your children not to play games using the internet connection. Is this possible in this age with children of this generation? We leave the answer to you.

The second option is to silently turn on the QoS feature by configuring the router to give more priority to your VPN traffic and reduce the bandwidth for the video games.

10. What is the difference between a modem and a router?

Many people confuse between the router and modem and assume them to be the same. These are two different devices that look similar but perform various functions.

Routers allow multiple devices to join the same network. However, to access the internet, it is necessary for the router to connect to a modem. You can connect the modem to your router and ensure that all devices connected to it access the internet.
