Just like how one cannot envision a world without food, water and air, one cannot imagine the current world without the internet. The Internet, which was once a luxury, has become a necessity. Most people around the world have computers and laptops which swiftly connect to their residential or workplace Wi-Fi, which enables them to use the internet to transfer and acquire data. But the act of our devices getting connected to the internet is something that we have all taken for granted. How many of us actually know the process behind every device connecting to an available network?

A Network Interface Controller (NIC) is a card that is embedded onto every computer’s motherboard. It is both an input and output device. It recognizes the presence of a network and connects to it upon the user’s command. Without this hardware component, the internet would have never attained its omnipresent, omnipotent status. Ethernet NIC is one of the most popular NICs that are in use and is typically integrated into every motherboard of a laptop/ desktop.

But in some cases, NIC may not have been embedded, the embedded NIC would malfunction or the device, by itself, would require an additional network card. In such scenarios, the device would not get connected to the internet, despite the network being stable and sufficiently strong. One may not want to add a cable since it would restrict one’s usage. Or one’s internet speed would be very low, despite using a strong network. For all these troubles and a lot more, there is only one solution.

The Wi-Fi card or rather, the best Pcie wifi card is a sure shot solution to most NIC- related issues. 

What is a Wi-Fi card?

It is a card that can be purchased separately and integrated with the motherboard, so one can connect to any network seamlessly and if one wants, one can also increase their internet speeds, especially when one is using performance-intensive, internet guzzling applications like gaming and certain simulation software. Also known as LAN cards, they help in quick, easy and wireless connection with a network or for that matter, even with a hotspot, enabling us to browse on the go, from wherever we are and giving us the flexibility to choose the network we want to connect with. It also significantly reduces one’s expenses in setting up internet connectivity, especially in corporate environments since cabling costs are practically non- existent.

Things to consider before buying a Wi-Fi Card

When more antennas are used, more signals can be picked up and more number of devices can be connected, with each consuming a large amount of bandwidth. This increases reception and internet speed, especially when multiple devices are connected

One must always remember that speeds of Wi-Fi cards are not absolute but relative. They heavily depend on the network they are connected to. However, there are Wi-Fi cards that give high throughputs but even that depends on the network

When devices work for a long time, they tend to overheat and that is a serious threat to the safety of the device. Hence every Wi-Fi card must have a proper heat dissipation system such that heat is dissipated equally to all components, cooling action is uniform and the core components are not affected.

This ensures the safety of the data transmitted on the network. It protects data privacy by preventing access, interception and interruption from devices that are not the designated recipients of the data being transferred. 


It stands for Peripheral Component interconnect, which directly connects peripherals to the computer’s processor. 

It is basically the amount of data that passes from one device to another in unit time. 

It depends on the user’s requirements. USBs don’t need any installation but are slower than Wi-Fi cards. Wi-Fi cards, on the other hand, transfer data thrice as fast as typical USB cards but have an intense installation procedure and are more expensive. 

The user must sort his requirements, compare with the features offered by each WiFi card and its price, check whether the wifi card is compatible with his OS before making a decision. 

Dual bands support both 2.4 GHz and 5GHz bandwidth. They have higher wireless range, faster data transmission and longer bandwidth than single bands, hence they must be chosen. 

Final Verdict

The user is advised to evaluate the merits and demerits of each product by comparing it with his requirements, before making a decision. However, the best product out of this bunch is the TP-Link TL WDN4800. It is highly compatible with all devices, has a flexible antenna for better reception, efficient heat sinks which ensure the safety of the device and the user, and is the best choice for energy-intensive, throughput- dependent applications like gaming and streaming high-quality videos.
