PCIe WiFi Card Buyers Guide


It is not difficult to find a great PCIe wireless card, but you need to consider some things. First, you need to know what you are looking for so that you end up with the most suitable PCI express wireless network card.

Number of Antennas

All wireless PCI cards will have at least one antenna. In addition, some have external antenna arrangements that plug into the main card using special cables supplied with the card. So how many antennas do you need?

The bottom line is that usually, more antennas are better. With more antennas, you will be able to carry more data. Each one of the antennas connected to your dual-band PCI wifi card is really its own network. Every single antenna will carry its own level of data.

Quality of the Antennas

It is not just a matter of the number of antennas you have when choosing a Wi-Fi adapter. You need to look at the quality of the antennas as well. Pay attention to the size of the tubes. The size determines the data-carrying capacity and the range.

A stock antenna will not be that impressive, but with some Wi-Fi adapters for your PC, you can replace these with higher-quality antennas. It is important that you can move the antennas around easily as this is important to find the optimum signal levels.

The Speed of the Card

Think about how fast you want your PCI express Wi-Fi card to be. This is not a calculation to perform in isolation because you need to consider the entire network. However, most of the PCIe wireless cards available these days will have a reasonable speed even at the lower end of the pricing scale.

If you know that you will need the fastest possible PCI Wi-Fi adapter for your desktop, then lookout for this when comparing the different products available. Naturally, you will pay more for fast PCI adapters prepared for this.

What Operating System?

Most modern dual-band PCI wireless cards will work with computers running Windows 7, Windows 8, and Windows 10. But what if you have a Mac or Linux machine or an older Windows operating system?

You need to check the specifications from the manufacturers. For example, in the descriptions of most wireless PCI adapters, you will see what operating systems are supported. If you don’t check for this, you can be disappointed if the card doesn’t work.

Cooling of the PCIe Card

The wireless network cards heat up quickly, and if they do not have the right heat dissipation components, they can stop working. Therefore, always check whether a heat sink is included with any PCI wireless card you are considering.

Size of the Card

This might seem strange, but some people own computer desktops that have a small form factor. There may be a problem with installing certain PCI Wi-Fi adapters into smaller machine cases, so always check the dimensions of the card before you purchase it.
