What is WiFi extender and how do they work? What are the advantages and disadvantages of various WiFi extenders that are available in the market?

Wifi Extender

WiFi extenders are one of the most commonly used networking devices in today’s era.

Reason for their so much popularity is their affordability and performance.

These WiFi extender devices are capable of resolving your network related problem with great ease and that too at low prices.

For instance, if you want to extend the network range of your existing network, then you will require to set up a new networking device.

In such a case, you can go for the network router, network switch, and any other network device, but they will hit hard on your pocket.

Whereas in case of WiFi extender devices, you can extend existing network coverage and that too with much lesser cost than in case of the network router or network switch.

Another advantage of these devices is that they come with varied sizes.

WiFi extenders are compact-sized devices, whereas other networking devices such as router or switch are comparatively larger.

At the same time setup process of WiFi range extenders are too simpler than that of other networking devices.

So we can easily conclude that these features make WiFi range extender as a preferred choice over other networking devices.

Now comes the second question that is for which extender to go with.

Answer to this is that you can choose among various WiFi range extenders available in the market as per your choice.

There are multiple brands which provide such devices with which you can go, such as

NETGEAR WiFi range extender, Linksys range extender, TP-Link WiFi range extender, D-Link WiFi range extender, Belkin range extender, and many other.

You can go for any brand as per your requirement whereas essential characteristics as well as the advantages and disadvantages of these different extenders we will discuss extensively in coming sections.

You can take reference of them while choosing among different extender devices.

But before that, let’s have a look at how these extenders work.

How WiFi Extender Works?

How Wifi Extender Work

As the name suggests, these networking devices are tasked to extend the already existing network coverage. That is the reason why they are named as an extender.

Thus their working will also depend on any primary device, whose signal they are going to extend.

For example, let’s say you have a network router in your network setup, which is transmitting network signal throughout your vicinity.

Then you add a WiFi extender in this setup.

Then this WiFi extender will be tasked to amplify the signal, which is coming from your network router. Then it will send this amplified signal to other networking devices that are present in your network.

Thus we can say that these extender devices work as an amplifier.

On the other hand, this amplified signal will be capable of being transmitted to quite a far end of your vicinity, thus will eliminate all dead ends or dead spots present in your network.

Reason for the same is that this amplified signal becomes capable of withstanding against penetration losses.

(Penetration losses are losses that are caused when a signal pass through various objects such as doors, walls, furniture, etc. which came in its way of transmission)

It also adds another benefit with it, and that is this amplified signal also reduce noises or disturbances that get induced in your signal during transmission.

So we can easily conclude that these WiFIextenders are although primarily tasked to amplify the signal but come with other advantages also such as noise reducer.

Now after understanding how these WiFi range extenders work, let’s move toward different WiFi extenders available under various brands.

We will discuss these extenders one by one.

So let’s get started.

1. Linksys WiFi range extender:-Linksys is one of the leading brands of WiFi range extenders.

We all know there is a vast difference between the speed of the router and extender.

And if in case your extender is using the same frequency band to receive a signal and transmit the amplified signal, then this may reduce the signal speed in a significant way.

But you can override this issue by going for dual-band WiFi range extender.

Another disadvantage is that the name of your extender network and router network will be the same just with the difference of _Ext as a suffix in case of WiFi range extender network.

It may cause a roaming issue in some cases.
