8 Best PCI-E WiFi Cards (2022)

When Ethernet is not a viable option, and your other options are delivering speeds way below what your router provides, your PC or laptop can get connected using the best PCIe WiFi card as well.

Having access to a reliable connection is crucial for everyone. Your devices will have either USB ports, Ethernet ports or card holders to help you get connected. Each has its own distinct advantages and disadvantages.

You must be thinking why on Earth you would ever need to be looking for the best PCI wireless card when everything works on your computer. Your computer may need an upgrade, or perhaps it is functioning on a much older wireless standard. This is when PCIe cards come in handy.

For today, we will focus on PCI and PCI-E wireless cards. The BlueGadgetTooth team dived deep into these networking devices, to see why they should be our preferred mode of getting connected.

What Is A PCI WiFi Card

PCI (Peripheral Component Interconnect) WiFi cards are networking devices that are installed in your computer using the spare PCI expansion slot. These help you get connected to nearby WiFi networks.

There are some devices that do not have the capability to connect to a wireless network. As wireless networks are the most common mode to get connected online, it is important that your device has the capability to get connected. A PCI WiFi card helps your device get connected to a network.

How To Choose The Best PCI & PCI-E WiFi Card

PCI-E Wireless Card Adapter Specifications

The best PCI or PCI-E wireless card should be chosen with these factors in mind:

Speed:

If you computer is not receiving a strong signal or you find that your speed is very slow, a wireless card will boost your speeds, offering better throughput.

Antennas:

If your computer is not located close to your router or modem, you could be at a slight disadvantage if you cannot get a strong signal. A PCI card has extra antennas that helps provide a stronger signal, offering better range and coverage without having to wire your entire house or buy WiFi extenders. Simply adjust 2 antennas at 45 degree angles facing away from each other, and point the third one vertically for potentially accessing more data streams.

Extension Cable:

Antennas come fixed with the wireless card. If your computer is at an awkward location placed against an object, surrounded by walls and other obstacles, you will have no option in adjusting the antennas. Many PCI-E cards allow the antennas to be connected to the card via a cable. This allows you to raise the antennas’ height, placing them away from obstacles to deliver a stronger signal to your computer.

WiFi Range:

The antennas on a PCI or PCI-E card pick up the signal and boost it, allowing the WiFi range to expand. This is great for people who work at a location which picks up weak signals.

8 Best PCI-E WiFi Cards For PC & Laptop

PCI vs PCI-E (PCI Express) – The Difference

If you have decided to use wireless cards, you will have to finalize between PCI or PCI-E cards. PCI-E is abbreviated for PCI Express, the latest standard.

The latest computers should have space for a PCI-E slot.

PCI-E is faster than PCI: Being the latest standard, PCI-E’s speed is a massive jump from the PCI card. In comparison, a standard PCI slot can deliver 133MB/s, whereas a 16 slow PCI-E can handle speeds up to 16GB/s.

Different Interfaces: PCI-E uses a serial interface, replacing the older parallel interface used by the PCI cards.

Sizes: PCI slot sizes are fixed, making it easy for any device to use. A PCI-E’s slot size can vary depending on the type of PCI-E card being used. Bigger cards can have a maximum of 16 lanes, with each lane delivering 1GB/s, this equalling 16GB/s. While some PCI-E slots will shorter for 1x gadgets.

Popularity: As of now, PCI cards are more commonly used by manufacturers, even though PCI-E cars are far superior, simply because devices have not progressed to super fast internet speeds which warrants the use of a PCI-E card. PCI cards are simpler to use as well.

Reasons To Use A Wireless Network Card

Wireless Network Cards help to pick up a signal better than the networking hardware on your computer. If your computer is located at a spot which experiences poor signal, a wireless network card would be just what you need. You should consider getting a wireless network card if your desktop computer has available PCI slots and you want to keep your USB slots free for other devices.

If you care about the strength of your signal, and have a lot of online activities which involve heavy downloads and uploads, a wireless network card is perfect for you.

WiFi Card vs USB Adapter – Which One Is Better

Both wireless cards and USB adapters can get you online. Read on to know the differences between the two.

Wireless Card:

PCI adapters have been used from the beginning since wireless connections were a thing. You just have to plug the wireless card into the PCI slot in your computer to maximise your signal. The antennas on the PCI cards can be adjusted to capture the signal.

As PCI cards have antennae, they are more suited to gaining access to a stronger signal than USB adapters. Most PCI cards come with at least 2 to 3 antenna attached. A huge plus point to PCI cards is that their antenna can be easily detached from the card and replaced with a better antenna that can pick up the signal. This option may not be available for many USB adapters.

Using a PCI card keeps your USB slots free for other uses. USB adapters can heat up with a lot of internet usage, while PCI cards can handle the data transfers with ease.

USB Adapter

These are newer as compared to PCI cards and were not as well received. Their popularity has grown over the years due to their ease of installation. Just plug in the adapter into your USB port and you’re good to go!

You need to open up your computer to add the PCI slot, which is more work, leaving with you a slight chance you could do something wrong if you don’t know what you’re doing.

There are various types of USB adapters, some of which come with a cradle – where you can extend your adapter with a USB cable that plugs into your computer, with the adapter being in a cradle. This can be placed at a distance away from your computer, where the strongest signal is available. This is similar to a PCI antenna extension.

Also, most laptops these days are equipped with a WiFi adapter in built into their hardware. If damaged, it is hard to fix without professional help. There are not many laptops that come equipped with a PCI slot, while USB ports are still very common.

Which Is Better?

If you don’t want to deal with the hassle of installing a PCI card and are looking for convenience– a USB adapter is a good choice. However, if you want better wireless speed, strength and coverage, you should go for a wireless card.

PCI-E Connection, Size and Pins

There are versions to PCI Express cards – Version 1.0, 2.0 and 3.0. Fortunately, the latest versions are all backwards compatible.

Different PCI-E sizes have different number of pins. If these numbers confuse you, don’t worry about it. The cards will easily fit in your PCIe slot. The 11^th pin is always left unused. After this pin, ‘x’ amount of pins can be added by the manufacturer.

To briefly share info on PCIe card pins and sizes:

PCIe 1 has 18 pins and is 25mm in length

PCIe 4 has 39 pins and is 39mmin length

PCIe 8 has 49 pins and is 56mm in length

PCIe 16 has 82 pins and is 89mm in length

How To Install A PCI-E WiFi Card

It may not be as easy as installing a USB adapter, but trust us, it sounds more complicated than it actually is.

Step 1: Turn off your computer’s power

Step 2: Open up your computer’s removable back panel

Step 3: See where your PCIe slot is located

Step 4: Remove your PCIe default protective plating

Step 5: Push in your PCIe card into the slot

Step 6: Install the wireless card by screwing it in with the screws from the protective plating in Step 4.

Step 7: Screw in the antennas which came with your wireless network card

Step 8: Place the removable panel back and close it up. Turn on your computer and ensure that all drivers are installed.
