Best PCI-E Wi-Fi Card For Desktop Computers

There are a number of ways to connect your desktop computer to your local network.

These include via Ethernet cables (the most traditional and stable connection type), via wireless adapters, and via PCI Wireless cards. Each of these methods has its own distinct advantages and disadvantages, but today we will take a look at PCI & PCIE Wireless cards.

So, without further ado, let's take a look at the best wifi card for PCs.

9 Best PCI-E Wireless Adapter Cards For Your PC

1. Asus Dual-Band Wireless AC1900 PCE-AC68 Adapter Card (Best All-Rounder)

This is a superfast adapter (with 802.11ac chipset) capable of delivering transfer speeds of up to 1.3Gbps. It is dual band, great for online gaming or HD video streaming, and includes fully flexible external antennas so you are more likely to be able to keep a consistent connection, by angling them to your home's aesthetics.

If your computer is further away from your router or wireless access point, this card also comes with an extendable external antenna (to help maximize wireless line of sight) which can be perfect if you have struggled to get good connections with other cards.

Much better to have your antennas as far away as possible from the back of your likely cramped PC.

Contains a heat sink to help dissipate high temperatures.

2. TP-Link Archer TX3000E AX3000 Wi-Fi 6 Card (Best PCIE card for Wireless AX)

This TP-Link Archer also uses the new 802.11ax (wifi 6) wireless standard which means you can theoretically get speeds of up to 3Gbps (over 5 & 2.4GHz wireless bands) using this adapter. Online gamers and HD video streaming junkies rejoice!

It also utilizes Bluetooth 5.0 which could come handy for any gaming peripherals, like headsets, for example.

Basically this is a great PCI card for those who want to harness all the power from their Wi-Fi 6 router. It's also backwards-compatible with Wireless AC and N should you have a really old router!

Also contains a heatsink for contained cooling.

3. Gigabyte GC-Wbax200 2x2 802.11AX Dual Band Card

This Wireless AX Dual Band adapter uses the 2.4Ghz and 5Ghz bands to give you theoretical speeds of up to 2.4Gbps. Of course, it is compatible with AC and Wireless N standard routers/access points.

This is another card that supports Bluetooth 5.0.

This 2x2 MU-MIMO card also has a detachable antenna, making it easier to capture the most wifi signal in your home.

4. Asus PCE-AX58BT (AX3000) Wi-Fi 6 Wireless AX Card

This wireless card from Rosewill is another high end product that uses the 800.11ax Wi-Fi standard. It therefore offers theoretical speeds of up to 2400Mbps on the 5GHz band and 570Mbps on the 2.4GHz band.

OFDMA and MU-MIMO technologies help you get more out of your Wireless AX router. 

This is another card that supports Bluetooth 5.0 allowing you to connect your headset and speakers etc, with better coverage.

The PCE-AX58BT works with older network technologies as well (AC & N).

5. TP-Link Archer T6E AC1300 Wireless PCI-E Card

This card is less powerful than many on the list above (we're back to the Wireless AC cards again) but nonetheless offers some good features that could make this a solid buy if you are on a budget.

With theoretical top speed of 1.3Gbps (over two bands), it's still pretty decent.

The antennas are detachable and there's 2-year warranty to help give peace of mind.

Oh, and there's a heat sink to keep the temperatures down.

6. Asus PCE-AC88 4x4 Wireless AC3100 PCIe Adapter

The Asus PCE-AC88 is now the flagship desktop card from Asus, taking over from the still, very credible, PCE-AC68 above. We kept the AC68 at the number 1 spot, because it's still a solid wifi card, but now even greater value, due to its dropping price.

This 4x4 adapter (that's 4 receive by 4 transmit antennas) is for those that will pay whatever the cost, for the latest and greatest. The antennas are adjustable and connect via a cable, to give you more flexibility with positioning correctly for optimum signal.

This card is "MU-MIMO supported", so you can have up to 4 wifi streams concurrently (as long as your router supports it). This will help with connection reliability, and you should see an increase of data throughput. Sweet!

Just like components (and peripherals), overheating can be a problem...causing bottlenecks and potentially system crashes. In case the PCE-AC88 is "getting hammered", Asus have included a customized heat sink, to help keep cool.

And so this is how we reach the 3.1Gbps in speed. Bear in mind, it's cumulative over both bands (2.1Gbps on the 5GHz 802.11ac, and 1Gbps on 2.4GHz Wireless N). And yes, it's theoretical too....but if your desktop is positioned in an optimum position relative to your router, and you set up the external antennas correctly, you should enjoy decent wifi speeds. Bring it on!

7. Gigabyte GC-WB867D-I Wireless AC PCI-E Adapter with Bluetooth 4.2 Connectivity

The GC-WB867D-I from motherboard giant Gigabyte, is an 802.11ac offering. Ok, not quite up there with the Asus AC cards, but this is still pretty powerful, with theoretical speeds up to 867Mbps. It's a dual band (2.4GHz & 5GHz) card.

This card, like some others on our list, has detachable antennas (2x2) that are attached by a cable, letting you position the antennas in the best position for the aesthetics of your home.

Also has the option of connection via Bluetooth (4.2) for those who may want that. Desktops, that actually have a Bluetooth option, tend to have a relatively poor range. This should hopefully change things within that department.

8. Rosewill RNX-AC1300PCE 802.11ac Wi-Fi Adapter

Another dual band wireless card, and again it's from Rosewill. 

This is again Wireless AC (Broadcom chipset), but with cumulative speeds of 1.3Gbps (867Mbps on the 5GHz, and a further 400Mbps on the 2.4GHz), so not as quick as the RNX-AC1900PCE AC1900 card above. It also has Beamforming technology for improved coverage.

Note that the antennas are affixed to the card, so sadly no option to position in the best possible position for your PC. The antennas are adjustable, however.

9. Asus PCE-N15 802.11N Wireless Adapter Card

Ok, so last, but not least, we have a basic Asus adapter. A little Wireless N card that will get you hooked up. Don't expect any magic to happen (online gaming enthusiasts, look elsewhere!) - like with the other Asus cards above. The PCE-N15 is basically a no-frills card that gets you onto the network at not-so-breakneck speeds...

The antennas may be adjusted to your liking, and you can use the WPS connect option for wireless pairing....although we don't recommend this method if you're security conscious...

Although quite an old card, it is supported within Windows 10, and offers easy installation.

What Are PCI Wireless Cards?

PCI Wireless cards are devices that are installed in your computer case using a spare PCI expansion slot, and they allow you to connect to a nearby wifi network.

Nowadays, as Wi-Fi is pretty much the most common way to establish an internet connection (via your router), it is generally quite important that your computer has Wi-Fi capability. A PCI Wireless card is, therefore, one way to connect a PC that doesn’t already have wireless capability to the internet wirelessly.

Why Use A Wireless Network Card?

The most obvious reason to use a wireless network card is to allow a PC that doesn’t already have a wireless connection.

While an Ethernet cable is a solid way to connect to a local network and in some cases, such as for high intensity online gaming, the best case, it is often not practical to have wires running throughout your house.

A wireless network card however will allow you to connect to your network, wirelessly from anywhere within range of your wireless router.

There are some occasions where using a wireless card is not the best option however. For example, if your PC is a laptop computer. This is because laptops either don’t allow you to connect a wireless card (well a pcie card, at least) or even if they do, the size and antennas found in a wireless card would ruin a laptop’s portability.

Of course, your desktop PC may already have wifi capabilities. But if the radio isn't particularly powerful, the wireless standard is a little older, or if the antennas are buried within the case, then it may be that you aren't enjoying the best wifi experience.

One option is to use a spare PCI slot on your mobo (mobo is short for motherboard - all the geeks know that, hehe) for a wifi card that is Wireless AC and has fully-adjustable antennas with an extension cable for more position options. 

And don't worry, we're going to show you how to get them up and running, for easy installation

Wireless Card vs USB Adapter - Is a PCI Wi-Fi Card Better Than a USB Adapter?

Both wireless cards and USB adapters have their plus points and negative points.

First let’s take a look at USB adapters. If you want the simplest way possible to connect a computer without wireless capabilities (or to improve the devices built-in wifi) to a wireless network, then a wireless adapter is certainly the way to go.

The only setup generally involved is plugging the adapter into the computer (into one of the spare USB slots). The computer should then install all the correct files, using Plug & Play, and you will generally be able to connect to a wireless network within seconds of plugging the device in.

USB wireless adapters are also good for laptop computers. These smaller portable computers don’t have the space or features required to allow a PCI card (well, the ones we're talking about today) to be installed so a wireless adapter is often the way to go. You can upgrade the internal card on some laptops. We wrote an article about it here

Recommended USB Adapter: Netgear AC1200 A6210

There are certain occasions however when wireless cards are the best choice to make. If for example your computer is a bit further away from your router and you struggle to get a consistent signal, the extra antennas on a PCI card mean that you will often get a much stronger signal which can boost coverage distance.

Of course you also get the benefits of having an extra USB slot if you use a wireless card.

It is also worth noting the difference between USB 2.0 and USB 3.0 adapters. If you are using a USB 2.0 adapter a wireless card will likely give you a much higher throughput and as such you should get a faster connection.

The difference between the latest USB 3.0 adapters and a wireless card is, however, less likely to be as pronounced.

Ok, that's great, but what about wireless cards....

Well, they are often a more solid bet for desktops, because they often sit in the same position 100% of the time and often in dark remote corners of a room. Yes, USB sticks are fine, but due to where PCs are physically positioned, the PCI expansion option can often be more preferred.

We'll come onto these particular reasons more later.

PCI vs PCI-E (PCI Express), Does It Matter?

Best PCI-E Wireless Adapter For Desktop PCs - Asus PCE-AC68 AC1900 Wifi Adapter Card

PCI-E Card

If you do choose to use a wireless card to connect to wireless, you will still have to choose between a PCI and a PCI-E (PCI Express) card. Sometimes referred to as just a pcie card

PCI-E is the newer standard and if you have a recently bought computer you will likely have space for a PCI-E slot.

PCI-E cards offer more bandwidth than PCI cards and because of this it may seem like a great idea to buy one of these cards.

However, before you do, it should be noted that PCI-E cards often offer more than enough bandwidth that can be utilized for most user's internet speed, although nowadays, ISPs are offering internet connection speeds that are challenging this theory.

It could perhaps be worth buying a PCI-E card if you're doing a lot of local network file transfers but for general internet connection, it won’t matter which type you use. Although, to be honest, the vast majority of cards sold these days are PCI-E, and it's most likely that's what your mobo will accept - unless you've resurrected a very old PC!

PCI-E Pins, Size & Connection

There are three different versions of PCI-E versions 1.0 , 2.0 and yep, you guessed it... 3.0

Luckily, all versions are backward and forward compatible with each other.

There's also the number of pins to think about, and the length. Well, you don't have to think too much about it, because they will all fit into a PCI-E slot. The 11th pin is always solid and unused. After this "pin", the manufacturer can add a certain amount of pins.

You can see the standard number of pins and the lengths in the table below. 

PCI-E Size

No. of pins


PCI Express 1



PCI Express 4



PCI Express 8



PCI Express 16



Explaining The PCI Jargon

When you're hunting around for the best pcie card, you'll see a lot of acronyms. What do they mean? Well, here's a short list of the most common acronyms you'll like come across when you're searching for your next wireless adapter, and a basic explanation of what it is and does...

PCI (Peripheral Component Interconnect) - Old skool slots on a motherboard. One particular way of connecting PCI cards for networking, USB, TV cards, and anything else that was a popular connect around 10-15 years ago.

PCI-E (Peripheral Component Interconnect Express) - A newer version of PCI, that has less pins, but much greater throughput (bus speed). Some graphics cards have also used PCIE over the years.

802.11ac - Also known as Wireless AC. A fairly new, and fast IEEE wireless standard, that uses the 5GHz radio frequency to transmit and receive data. Wireless AC is backwards compatible with older wireless standards, including Wireless N

802.11n - Also known as Wireless N. An older wireless standard, but uses both the 5GHz and 2.4GHz bands.

Dual Band - Devices that use both the 2.4GHz and 5GHz radio frequencies. 

5GHz - Wireless frequency range, within 5GHz. Faster than 2.4GHz, and less prone to interference as there are many non-overlapping channels to pick from. Range is not as good however...

2.4GHz - Within the 2.4GHz frequency range. Still the most widely used band. Wireless range is better/further than 5GHz, but is limited by speed and interference issues, as there are only three non-overlapping channels.

Gbps (Gigabits per second) - A unit of data transfer. The more, the better.

Mbps (Megabits per second) - Same as Gbps, but less fast.

N300 / AC3100 etc - The N or AC refers to the wireless standard as explained above. The following number is the cumulative theoretical data speeds over all radios.

Anything Else To Think About?

So, now we know what PCI and PCIE cards are and why a wireless card has its advantages, what else is there to consider?

More Antennas

More antennas mean the potential for more data streams (depending on your setup and devices), and faster wifi. You want to try to adjust your antennas to 45 degrees off each other. Our best antenna article might explain this better, but if you angle them at 45 degrees (and if a third one is available - leaving it totally vertical), then your chances of covering off all direction of wireless signal is increased.

Remember that wireless signals can bounce off your furniture and walls, so by adjusting the angle of the antenna off each other, you have a much better chance of capturing wifi signal as efficiently as possible.

Extension Cable

Most wireless cards have the antennas screwed in directly into the card. This means there's no options for adjusting the height of the antennas. This can be a bit of a problem, especially if your PC is tucked down at floor level under a desk, with the rear of the case tight against a wall. Your wifi signals will likely have to traverse the case, walls, desk or a combination of the three! 

Luckily, some PCI-E cards have a cable that connects the antennas to the actual card. This means you can raise the height of the antennas, and place them away from your PC and any furniture that might lead to wifi performance issues.

How to Install A Wireless PCI Card

How to Install A Wireless PCI Card

Despite being harder than installing a USB adapter (I mean, you literally just plug in and play!), installing a wireless card isn’t as hard as you may think. So yeah, easy installation.

However, it does involve opening up your computer so you should check out how that will affect your warranty before doing it. If you are unsure what to do, it is probably worth getting an expert to do it for you.

Here is the simple process required to install a wireless network card.

1. Turn off your computer

While it may seem obvious, this step is always mentioning as you can do your computer and yourself some real damage if you mess about with a computer without turning off the power.

2. Open your computer case

Most computers have a removable panel you can remove to get into your computer. It is worth checking your computer’s manual before doing this to make sure you don’t damage your computer.

3. Identify your PCI/PCI E slot

This is where you will have to install your wireless card. If you are unsure of its whereabouts again check the manual.

4. Remove the protective plate

Usually there will be a protective plate over the PCI slot. This can usually be removed by simply unscrewing the plate.

5. Align your wireless network card and the PCI slot and push in the card

Make sure all the important bits are aligned and that the chips are facing the bottom of the case. After this simply push the card into the slot.

6. Screw the wireless card back in

Using the screws from the protective plate in step four, fix the pcie wireless card in place.

7. Attach the antennas

Your wireless card should have come with some antennas. Now is the time to screw these in place.

Here's a handy video demonstrating how to install a PCI wifi card...

8. Close the computer and finish!

Now your card is successfully installed, simply close your computer and turn the PC back on. The final step is to install the drivers on your PC operating system which will be an automatic process if you use Windows 8 or above.

You may require a CD to install the drivers if you use Windows 7, although we'd be surprised if Windows 7 couldn't find the drivers for you You shouldn't be using Windows 7 anymore!

PCI-E Wifi Cards: In Short

To conclude, a wireless card can be a great way to connect a desktop computer to a wifi network. They offer quick speeds, good range and are relatively easy to assemble if you don’t mind doing a bit of manual work. To get more flexibility with positioning, try to get one with an extension cable. This will let you place the antennas in an optimal position, comparative to where your PC case is.

Of the cards we have looked at today, each one has positive features and reasons for you to buy that specific card.

If you don't have any wireless connection on your desktop, and you just need really basic wifi, then a Wireless N card will probably be enough for you - for example the Asus PCE-N15. It will get you connected, and will use the 2.4GHz frequency band, which has a better coverage range. 

If you are after the best possible performance for your card, then the Archer TX3000E could well be the way to go. It has the top of the range features you could need such as 802.11ac, Beamforming technology and four external antennas, which extend off a cable. 4K video streaming and other high-bandwidth, lower latency loving tasks, should work better with it

Remember that you might be just fine going with a USB wifi adapter. Just bear in mind that you'll lose one of your valuable USB ports, and you may not get the same wireless range that you could potentially get with the external antenna option of PCIE cards.

  1. I looked at all the cards on None of the say they support Windows 10. Is this article out of date?

    1. · Edit

      Hi James,

      I don’t currently have access to test, but a quick Google search shows that Win 10 drivers for all cards appear to be available at the manufacturer websites: <<< search for "RNX-AC1900PCE" So looks like all above appear to be supported, not sure what more research I could do. The following do not appear to have Win 10 support: 1) TEW-703PIL

      2) and the P-Link TL-WDN4800

      They are old .11n cards, so not surprising.

      Disclaimer: We highly recommend purchasing a card with a free returns policy in case there is an issue.

  2. Is there really that much difference between one PCI-e wifi card and another one? It’d kinda seem like there’s no such thing as a “good” wifi card or a bad one, it’s like it either works or it doesn’t. Sort of like how HDMI cables try to claim to give you “better graphics” but really either the cable works or it doesn’t, there’s no such thing as “better” HDMI cables (other than perhaps being constructed better and being more sturdy/etc.)

    1. · Edit

      Hi Mavis,

      There is a difference for sure (in a lot of cases). The key is looking at the quality of the amplifier and antennas on the card.

    2. Hi Mavis,

      I seem to be real late to the party here, but I was reading through the comments and thought I’d be able to chime in. HDMI lists a set of minimum specs, and while some products lie and don’t meet them, I.E. don’t work, others that do meet them do have very different levels of quality. For the average user, any HDMI cable SHOULD work, but it’s edge cases like research or military, where things HAVE to work right that some of the fancier ones make a difference. You are paying extra for both quality and consistency of how your signal is transmitted.

      Now for these WiFi cards, it’s a bit more complicated than HDMI. While yes, they either work or they dont, its how they handle non-ideal conditions that really separates them. My roommate likes to play with high voltage/current things. These generate noise. If say, you are super unlucky (like me), you may have a ton of environmental noise around you. This is where the amplifiers and filters bestwirelessroutersnow was talking about come in. They help clean up your WiFi signal and keep everything nice and working right under intense EM conditions. If you’re like me and need a decent signal a few feet from a high voltage transformer, you may need a better card or maybe a Faraday cage… Otherwise anything that people say is consistent and meets the required specs (N or AC or whatever you need) should work. If not, return it and get a different one.

      In the end, you probably don’t need the top of the line stuff. If you do, you are most likely already painfully aware of the issues middle of the road equipment can cause. If you would like to know more about some of the engineering behind the equipment and what makes it good or great, feel free to reach out.


  3. I was looking for a card of this nature for a very long time and this was certainly very helpful. Thank you so much!

  4. Everybody say USB port Works better then parallel port & PCI cards. I don’t agree with that at all. PCI ports are always better then USB adapters when it comes signal strength.

    1. · Edit

      Thanks for dropping by. That can certainly be the case!
