PCI-e wifi cards can exert more power and performance because of the PCI-e connection.

Next is, they are just built better and have a stronger wifi connection. The first advantage is that it directly connects to the motherboard, which can help the speed and stability of your connection. There are a few advantages of using a PCI-e wifi card over a USB wifi adapter. You will want the most speed you can get because it is not directly connected to your motherboard. When installing a USB wifi adapter make sure it’s plugged into a USB 3.0 port to improve the maximum efficiency. Having a USB wifi adapter is a lot more user-friendly because the only thing you have to do is plug it into a USB port on your pc. Having a third antenna will make this signal even stronger assisting the two other antennas when they start to bottleneck. However, with 2 antennas you will have one dedicated to receiving a signal to your computer and another sending your computer’s signal out. If your wifi adapter has only one antenna, it will not be able to send and receive the signal at the same time making your connection slow down. Although you can connect to the wifi with 1 antenna or even 0 antennas, the extra antennas provide a stronger connection. Usually, the wifi card comes with either 2 or 3 antennas, which will provide your computer with a better signal. This is great because the wifi card will be directly connected to the motherboard, allowing it to perform at its maximum potential. The PCI-e wifi card connects to your computer via the PCI-e slot.

Still not sure which one to buy? I will go through the pros and cons of both the wifi card and USB adapter, that way you can make your final decision. There isn’t a big difference between the two wifi adapters, but there are some features that might make you pick one over the other.

Whereas a USB wifi adapter is more user-friendly and easier to install but will have a worse connection because it doesn’t directly connect with the motherboard. PCI-e Wifi cards offer a better wifi connection to your pc because the wifi card connects directly to the motherboard. Then, a few months later I switched to a PCI-e wifi card, and here is what I found. I ended up buying a cheap USB wifi adapter and it worked well for the first couple of weeks. When I first built my computer I was too far away from my router to connect an ethernet cable, so I had to buy a wifi adapter for my pc.
