Things to consider when picking the best wireless adaptor for your desktop

Which is best: USB Wireless Adaptor for desktop or an internal PCI Wireless Card?

This usually is the first question that needs to be answered when choosing the best wireless adaptor for your desktop. Should I pick a USB wireless adaptor or a PCI wireless card? The difference between both solutions depends on your needs and how comfortable you are with opening a desktop tower.

USB wireless adaptors are by far the easiest to install. If you’ve ever used a USB stick to transfer files between one computer to the other, you are golden. If not, don’t worry, it is a simple plug and play solution that will get you connected to the internet in no time.

Some tools will be needed to open your desktop computer to reach the PCI slot.

So, which one is the best wireless adaptor for my desktop? There is pros and cons for both USB and PCI. Gamers will most often pick the PCI card as it offers faster speeds and better range, thanks to the multiple antennas that can be mounted on the card. The USB however, trades performance for convenience and decent speeds can be achieved with the newer USB 3.0 interface.

Wireless Frequency 2.4GHz or both 2.4GHz/5Ghz?

WiFi equipment such as your home or work router use either the 2.4 or 5 GHz frequency band. You might have heard the term dual band access point; this means that your router will emit both signals.

Your wireless adaptor will, by default come with the 2.4Ghz frequency. The 5GHz frequency is optional but has become the new standard in all top rated wireless adaptor for desktop. The 2.4GHz frequency is the long-standing signal that has been used in over a decade while 5GHz is the latest frequency. There are a lot of devices that live in the 2.4 frequency band, such as other access points, microwaves, ovens, cordless phones, wireless cameras and etc. This frequency is very loud, very busy, very congested and prone to interference.

The new WiFi standard 802.11n and 802.11ac have made a shift to 5Ghz. The benefit is less interference and more bandwidth. Most modern devices prefer the 5Ghz band. But by far the biggest downfall with the 5GHz network is the fact that it does not travel as far as the 2.4 signal.

If you want better range, use the 2.4Ghz. For better performance, it is recommended to use the 5Ghz if your router has it enabled. Thankfully, most leading wireless adaptor for desktop come with both frequencies.

What type of USB ports: 2.0 or 3.0?

The key difference here between the 2.0 and 3.0 USB interface is data transfer rate. USB 2.0 is an old standard of USB. This interface provides a maximum transfer speed of 60 MB/s. While on the other hand, USB 3.0 is a newer standard of USB and provides a maximum data transfer rate of 640 MB/s.

Before picking one or the other, we recommend you check your desktop to verify that you have a USB 3.0 port. Even the best wireless adaptor for desktop on the market will perform poorly if plugged into a 2.0 port.
