What Exactly Is a Router?


A router wirelessly transmits the WiFi signal from the modem given by your internet service provider (ISP) or one you purchased yourself to your home’s gadgets, such as laptops, smart speakers, TVs, smartphones, and tablets.


Routers generally contain connectors that allow you to connect them directly to a game console for example, via an Ethernet cable for quicker and more reliable WiFi connectivity. You mat also connect a printer to you home network with an Ethernet connection so that it can be shared by everyone in your household.


As part of your internet plan, your ISP may give you with a wireless router for a monthly leasing price. The device can sometimes act as both a router and a modem.


However, if your router is old or has a limited range, your WiFi signal may be too slow or weak to give internet access in critical areas of your home.  Automatic firmware updates are another characteristic of many current routers. This guarantees that your router receives the most recent security patches as soon as they are released, keeping you and your data safe.


Wireless Routers Types


Traditional single-unit wireless routers and a newer form of router known as a mesh router are both included in our rankings.


The first variety, which you just plug into your modem to form a home WiFi network, is arguably the most familiar. A single-unit wireless router may or may not be sufficient to spread WiFi throughout your home, depending on numerous factors such as the size of your property and the building materials utilized.


Mesh routers can help with this. These are made up of many units that you place strategically about your home, usually in packs of two or three, where you require the best internet connection. One device connects directly to your modem, then communicates wirelessly with the other two to form a big "mesh" network that effectively distributes WiFi around your home.


Getting a decent WiFi connection can be as much art as science, regardless of which router type you choose. Drywall and plaster will obstruct your router's performance; even uninsulated doors and floors, as well as the water in a fish tank, might degrade signal quality. Aluminum studs (found in office buildings and some new flats), insulated walls and floors, glass, and solid brick and stone are the worst offenders. The signal suffers the more floors, walls, and windows of any kind that are in the way.



Benefits Of Routers


A router is a practical way to connect several devices to high-speed internet, whether for business or home use. Before purchasing a router, you should examine a variety of factors, such as whether you require a twin or single band router. Although most consumers prefer single-band routers, dual-band routers do offer a number of significant advantages.


1. Multiple devices are supported.


If your Ethernet router only supports three to five devices, it may be necessary to purchase a second router to connect more computers to your network. This also makes it possible to connect to a hybrid network. Make a wireless connection using the second router, for example, if you wish to add Wi-Fi devices to your network.


2. Convenient


A wireless link is advantageous since it can reach far-flung networks and devices. Furthermore, it provides network isolation, which is useful when using routers to connect several devices (for example, LAN gaming or file transfers), because network traffic will not influence devices connected to the secondary router.


3. Internet usage should be separated.


A high-bandwidth router allows you to multitask across several devices, such as streaming music and movies, browsing the web, and checking email; in other words, you can browse the web while simultaneously streaming movies without encountering network traffic.


4. Simple file sharing


A router also allows for high-speed connectivity, which is necessary for things like streaming video and sharing files over a network. Despite the lack of a 5-GHz band, technological experts agree that this is a good way to stream and share video files as well as play games.


Despite the fact that they let you to connect several devices at faster internet speeds, they lack stable signal strength, especially when connecting multiple devices.


5 Things to Think About When

Purchasing a Wireless Router


A wireless router is required to set up a home Wi-Fi network. Because there are so many models with varied functions, choosing the proper router might be difficult. This shopping guide will assist you in determining the finest wireless router for your needs.


Keep in mind that your internet service provider may limit the functionality of your network equipment (such as your router and modem) (ISP). You won't get the full benefits of a high-end router unless you have a comparable internet package.

There are hundreds of router types available from dozens of manufacturers, however the following are the most important considerations:




What to Expect in Terms of Price

$50-$99 Suitable for a single user or a small family living in an apartment or small home for video streaming, video chat, and other basic online activities.

$100-$300 Ideal for larger houses and more intensive online activities such as high-speed gaming and live-streaming.

Ideal for large buildings with a lot of users. $300-$400+ Extra security features are frequently included in higher-end versions.




The speed of wireless routers is measured in megabits per second (Mbps). The initial consumer Wi-Fi routers offered 11 Mbps, followed by 54 Mbps 802.11g routers, 150 Mbps to 600 Mbps 802.11n routers, and now 802.11ac routers with speeds exceeding 1 Gbps.

Don't just look at routers with the fastest speeds. The real performance you'll get in practice will almost always be lower than the package's maximum rating. A high-speed router will not be able to compensate for a poor internet connection. If an ISP offers 25 Mbps service, a router capable of speeds greater than 1 Gbps will only work at 25 Mbps.

The router and the speed given by the ISP—whichever is slower—determine the network's maximum speed. So, if a router promises ultra-fast speeds but your ISP only gives a little amount of bandwidth, the router will only deliver that amount. The reverse is also true (that is, a slow router will deliver slow speeds even if you have fast bandwidth).


Buy a router that delivers speeds at least as fast as your ISP to enhance the speed of your wireless network.


Range of Wi-Fi


Do you need your router to reach a few rooms on one floor or a three-story house with a garage? The router's strength is determined by this function. Some single-unit routers may or may not be capable of delivering Wi-Fi throughout a whole household (depending on how big the house is and how powerful the router is). Consider a long-range router, a mesh network with several routers packed into one, or a Wi-Fi repeater/range extender if you have a vast area to cover. In large, multi-level homes or if you want to extend Wi-Fi outside, a second home router can be useful.




If you're new to networking or technology, look for a router with a user interface designed for first-time home buyers. Here's how to figure out which router you'll need:

The IP address of older routers can be entered into a web browser to access the router's settings. Because you must remember the password and be at home when making changes to the network, this technique is tough for beginners to maintain a network (such as changing the Wi-Fi password and other settings).


Smart routers are controlled using a smartphone app that connects straight to the network from anywhere, even when you're not at home.

If you want a cheap wireless router, go with the first type, because the convenience of the other type is usually what drives up the price. Furthermore, mesh Wi-Fi network solutions typically use a mobile app, whereas IP address-based routers are typically only seen with standalone devices.




External network adapters were once prevalent when routers were purchased. When brand-matched, networking providers occasionally introduced proprietary enhancements to their devices, resulting in somewhat better performance. Vendors can also evaluate compatibility with their own equipment rigorously.

Brand-matching your Wi-Fi router can make sense if you own some consumer electronics. Otherwise, look into the various brands and choose one you can trust.


Who Should Consider Purchasing a Wireless Router?


Because routers are an essential component of every network, anyone who requires Wi-Fi will require one:


Wi-Fi users at home. You'll need a router that can support all of your wireless devices if you want to access the web, stream movies, or play online games.

Offices. For most work environments, high-speed internet and Wi-Fi are required.

Businesses. If you own a business, you'll almost certainly need Wi-Fi to run it, and you may wish to offer free Wi-Fi to your customers.

Public Areas. Free Wi-Fi can be found in libraries, churches, community centers, and other public places.
