  • PCI-E 4: 39 mm (39 pins)
  • PCI-E 1: 25 mm (18 pins)

PCI Wi-Fi Card VS. USB Adapter – A Comparison

In terms of purpose, both PCI wireless cards and USB adapters can help you access the internet. There are a few differences, however, that set them apart.

A Wireless Card

PCI wireless cards have emerged as a go-to choice for maximizing wireless connectivity. You can plug one into the PCI port in your computer’s motherboard and adjust the antennas to get your connection up and running.

A lot of users set off in fear at the thought of opening their PC to embed a wireless card, and their reasons are legit. After all, working around with electrostatically-sensitive parts of your computer is no joke. However, once the card is successfully installed, it can boost the Wi-Fi signal reception.

Most of the wireless card models typically have two antennas. Some of them pack three to four antennas to scale the networking speed even more.

Multiple antennas take advantage of multiple-input-multiple-output (MIMO) networking, which can rather be complicated. On the upside, these can be beneficial in terms of signal strength and connectivity. Also, most wireless cards have Bluetooth capability, which is mostly unavailable in USB adapters.

The placement of antennas is a matter of concern with wireless cards. Some people have found that placing antennas between the computer case and the wall have negatively impacted the receptivity of the connection. Even though the antennas are power-packed, putting metal in between antennas and the source of your Wi-Fi signal can lead to poor signal strength.

A USB Adapter

A USB adapter works on similar lines as those of a PCI wireless card. You plug it into a USB port and it connects your device to a wireless connection. The biggest advantage of a USB adapter is that it’s easy to use, and you don’t have to fiddle with the sensitive components of your device’s motherboard. Moreover, a USB adapter is compact and can be used with a laptop or a desktop.

However, the manageability of a USB adapter comes at the expense of performance. Most USB wireless adapters don’t have external antennas and hence provide poor signal strength. Some models, on the contrary, have a single antenna but their receptivity isn’t any close to what triple-antennaed PCI Wi-Fi cards can provide.

That said, some people have had a positive experience of working with USB adapters and prefer them for the sake of intuitiveness.

Best Wi-Fi Cards for Desktop in 2021: Final Words

That’s a wrap to our review of the 9 best WiFi card for PC. We hope our effort helps you make the right choice for yourself. If you have any recommendations or suggestions, drop a line to us in the comment section below.

Some of the most common parameters for comparison of Wi-Fi cards for PCs are—wireless protocols, the number of bands, OS compatibility, stability of the connection, signal strength, and coverage area. While a majority of Wi-Fi cards we mentioned above run on IEEE 802.11ac, a few of them may not be compatible with previous versions such as IEEE 802.11n, IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, and more.

So, make sure that whichever device you choose should be compatible with previous versions. Also, you need to make sure that the device is compatible with the operating system of your computer since some of these may be difficult to install and operate in Windows 10.

For stability of the connection, optimized signal strength, and better coverage area, you need to ensure that the Wi-Fi card you choose must be integrated with proper heat-dissipating mechanism and has multiple numbers of antennas. A 3×3 is often the most suitable one for advanced operation. 

Another consideration should be the router antenna, which should be pointed in the right direction. It’s important because Wi-Fi signals are short and cannot reach beyond 150 feet from the source. Moreover, these signals can be blocked by metallic surfaces or absorbed by walls. So, the position of the Wi-Fi router antenna is important for internet speed and strength.

All the above-mentioned Wi-Fi cards have an omnidirectional antenna which emits equal strength electromagnetic wave in all direction. They are commonly used in Wi-Fi Routers and Wi-Fi Adapter. However, you also need to make sure that it can focus the signal in one direction with additional built-in technology. Moreover, detachable and upgradeable antennae are of great help in case you need to change for better in the future.
