Things To Consider

We’ve just explored some incredibly impressive PCI-e wifi possibilities, and we know you’re dying to click ‘confirm purchase’ already, but before you do that, it makes sense to run over some key wifi card considerations.

Data Transfer Speed and Bandwidth

Let’s start with one of the most exciting aspects of a wifi card, the connection speed. You can buy wifi cards with pretty juiced speeds these days, but it’s not as simple as buying the fastest one.

A lightning-fast wifi card is fantastic, don’t get us wrong, but it won’t speed up the network connection that your router has already established. Your card can only run as fast as this primary network connection.

So, what you need to do is find a wifi card that matches your established network speed. This way you’re not forking out cash for technology you can’t take full advantage of.

For things like competitive online gaming, we’d suggest looking for something with at least 1GBps transfer speeds. This should be enough to support pretty much any online gaming scenario, no matter how data-heavy the game is.

For standard usage, you can settle on something more low-key with transfer rates upward of 300MBps. On the other hand, if you want the ultimate wifi experience, why not treat yourself to something with a 2 or even 3GBps transfer rate?

Cooling and Signal Stability

Computer chips get hot. It’s just a fact of life. And it’s another fact of life that heat kills computer chips…it’s sort of Superman/Lex Luther, Batman/The Joker state of affairs. If a computer component gets too hot, you’ll begin to see a decline in performance and in severe circumstances, crashes.

When it’s your PCI-e wifi card that’s overheating, you’ll first notice your connection speeds dropping significantly. From there on out, your connection will become unstable. This is obviously something you’ll want to avoid, and the best way to prevent it from happening is to choose a wifi card with a dedicated heat sink.

These heat sinks collect the heat from the core components of the card and transfer it to benign areas where it can then be dissipated by your cooling system. It’s not the end of the world if you choose a card without a thermal solution, but you’ll have to take it upon yourself to keep it cool.

Range

Next on the agenda is wifi range, which is largely determined by the quality and number of antennas that come with your card. Besides making your wifi card look like a cute little bug, they’re responsible for receiving and transmitting the wifi signal, so in a way, they’re the most essential part of the card.

Generally speaking, a wifi card with more antennae will be capable of processing larger amounts of data across a wider area. Wifi cards that come with a dedicated unit for the antenna are preferable as you can place them strategically to maximize coverage of the area.

Furthermore, antennae aren’t made equal. The quality of their design has a direct impact on their range and signal strength. Some wifi cards will have detachable antennas, so feel free to make an aftermarket upgrade to boost your signal.

MU-MIMO

When multiple devices are drawing wifi signal from a router, the router can only communicate with one at a time. This basically creates a device queue. If there are only a few devices communicating with the router, you won’t notice you’re in a queue because the router communicates so quickly with each one. If there are more devices or more data-intensive applications, you’ll have to wait longer for the router to communicate with each one.

This is where MU-MIMO (multi-use, multi-input, multi-output) comes into play. It separates lines of communication, so each device has its own direct link to the network. MU-MIMO isn’t an essential technology, but if there are a number of you dipping into the same network connection, it’s definitely worth your while.

Wifi Generation

Wifi 6 is currently our highest performing wifi, but unfortunately, you can’t just buy a wifi 6 card and expect 2402MBps connection speeds. To reap the benefits of a wifi generation, every part of the network chain must be built using the same generation of technology. So, for instance, if you have a wifi 5 router, all your other connective hardware needs to be wifi 5 too.

FAQs

What PCI-e Wifi Card Should I Get?

You should get a PCI-e wifi card that makes the most of your primary network connection. Matching up the bandwidth is an important aspect of this process. You should also consider how much range you’ll need from a wifi card. Are you near the router or a staircase and two rooms away? More or better quality antennae can help boost coverage.

Are PCI-e Wifi Cards Better than USB?

PCI-e wifi cards tend to be faster and more powerful than USB wifi adapters. The reason for their unparalleled speed is that they plug directly into your motherboard, which negates the latency of a USB adapter having to transfer data through the I/O to your main board. PCI-e is also much faster than USB in the first place, so even if they both had direct access to the motherboard, the PCI-e card would be more efficient.

Do Wifi Cards Make a Difference?

A quality wifi card can make a huge difference to your computing. Firstly, you won’t need a cable physically connecting you to your router, freeing you up to set your computer up anywhere in the building. Secondly, they often provide such stable connections to the network that people use them in place of the integrated wifi in their motherboards.

Does a Wifi Card Give You Wifi?

A wifi card doesn’t give you wifi. Wifi is drawn from your main router. A wifi card simply allows a device to receive the wifi signal that’s already being emitted by your router. Wifi cards also boost the range of your router’s wifi allowing you to set up camp further away.
