PCI Wireless Cards

PCI Wireless cards are devices that are installed on your computer and they allow you to connect to a wireless network.

Nowadays as Wi-Fi is pretty much the most common way to connect to the internet and other networks, 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 wireless connectivity to connect to wireless networks.

While an Ethernet cable is a solid way to connect to a local network and in some cases, such as for high intensity gaming, the best case, it is often not practicable 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 most laptops either don’t allow you to connect a wireless card or even if they do the size and antennas found in a wireless card would ruin a laptop’s portability.

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 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. The computer should then install all the correct files 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 often don’t have the space or features required to allow a PCI card to be installed so a wireless adapter is often the way to go.

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.

PCI or PCI-E, Does It Matter?

If you do choose to use a wireless card to connect to your wireless network you will still have to choose between a PCI and a PCI-E (PCI Express) card.

Let’s take a look to see if there is likely to be any difference between the two formats.

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 both PCI cards and PCI-E cards offer more than enough bandwidth to be optimised for wireless internet, as the speed on offer generally isn’t as fast as the speeds they can handle.

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 use it won’t matter which type you use.

How to Install A Wireless PCI Card

Despite being harder than installing a USB adapter, installing a wireless card isn’t as hard as you may think.

How to Install A Wireless PCI Card

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.

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 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.

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 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!
