Best PCI WiFi Card

There are so many options to choose best PCI WiFi Card  from, you can lose your mind sorting them out.

Do I need a WiFi Card or Adapter ?

While convenient to be able to connect to a hardwired ethernet connection when able, sometimes the extra cords can get in the way, and become a real hassle when making room available for your custom computer.

This is why, when creating your computer, you may want to consider putting a wireless adapter into your build. It eliminates unwanted wires, and, with the right adapter, provides internet speed that rivals even the best wired connections.

What is it ?

Wireless network adapters are devices that are installed to allow the sending and receiving of data via a wireless network. This convenience is highly important for just about every computer, as wireless network adapters ensure that users enjoy flawless network and internet connectivity.


If you need to get wireless connectivity on your beige box, you have a few options: you can use either USB Wi-Fi adapter, a PCI-E Wi-Fi card, a new motherboard with built-in Wi-Fi.

Best PCI WiFi Card

One type of wireless network adapter are known as PCI wireless adapters- they’re intended for desktop computers. As long as your computer has an available PCI slot on your motherboard.

Most PCI-based wireless adapters come with multiple large antennas that stick straight out of the rear of your system and help maximize your throughput in a Wireless N environment thanks to a transmission technique called spatial multiplexing. Since you have to install a PCI adapter right onto your system’s motherboard, you’ll discover that it’s less convenient than a USB adapter if you ever need to move it to another system. But a PCI-based adapter, like the Xtreme N PCI Express Desktop Adapter (DWA-556) is an excellent choice if you want top-notch wireless power for a single desktop PC.

A PCI wireless adapter card connects to a desktop computer’s PCI bus. Because the PCI bus is contained inside the computer, the unit must be opened and the wireless network adapter installed inside.

When choosing wireless networking hardware for your new computer, the choices available can sometimes be overwhelming. Not only must you choose the right card, but you need to ensure you have the right antenna for your needs.

The specific card and antenna combination necessary will generally be based on 3 key factors: what you will be using the network-connected device for, what kind of wireless network you are connecting to and how far away you are from the source signal? If you know the answers to these basic questions, choosing the right network solution can be fairly easy.

2. TP-Link AC1750 Archer T8E PCI Express Adapter

For the fourth, and last time, on our list of PCI Adapters today, we see TP-Link. This time, they attempt to blow the competition out of the water with another of their Archer models, the T8E.

TP-Link AC1750 Archer T8EPCI WiFi Card

  • Combined speeds of up to 1750Mbps with next-gen Wireless AC technology
  •  Dual 5GHz (1300Mbps) and 2.4GHz (450Mbps) bands for lag-free HD video streaming and online gaming

  • Ad-hoc and infrastructure modesPros
  • Dual Band (5Ghz at 1300Mbps) (2.4Ghz at 450Mbps)
  • High bandwidth data transfer
  • Backwards compatible wifi


  • Compatibility with Windows 10

To start, this adapter is capable of lightning fast speeds. Capable of internet speeds of up to 1750Mbps across the adapter’s dual bands, the T8E is able to give users fast, uninterrupted internet while gaming online or during other activities.
If you happen to download a lot of stuff online, then you will like that the T8e offers higher bandwidth options, that reduces download times like never before. Even if you happen to be using an older wireless internet connection, you will still get the same great speeds out of the T8E, as the device is fully backwards compatible.
One major drawback that does come out of the T8E is for Windows 10 users, as there seems to be some compatibility issues with the device. While these issues can be fixed, the extra time and effort that goes into making the adapter work properly with Windows 10 can be more than some people wish to deal with.

I have found that while the driver hasn’t been updated since 2015, there is a recent video on TP Link’s website that describes how to get through some common troubleshooting issues.
All in all, TP-Link proves once again that they know how to make quality PCI network adapters. Dominating nearly half of todays list, if TP-Link is in the brand name, you know you will be buying a quality product. If you’re savvy computerwise, given the price and the speed that the T8E offers – I still think it’s worth it.

One unique thing about the T6E is that it is backwards compatible with some older wireless connections, including 802.11 a/b/g/n. Despite being backwards compatibility, the does not seem to be compatible with Linux operating systems, which seems like a slight oversight for an otherwise versatile adapter.
What is not an oversight is the wide wireless range of the T6E. Even if your computer happens to be on the other side of the house from your adapter, you can be certain that you will not lose connection thanks to the wireless network adapters large and strong signal range.
If you use a Linux OS, you’ll have to look elsewhere. For everyone else, however, the TP-Link Archer T6E is capable of giving your computer the strong wireless internet that you have been looking for.

5. Gigabyte GC-WB867D-I Rev PCI Express Adapter
