PCI WiFi Adapter VS USB WiFI Adapter
Likely you want to enable WiFi access on your desktop or laptop without wireless adapter to eliminate the need for so many cords. Well it is good your here to learn the difference.
PCI WiFi Adapter
I’d like to start this one off by saying if your getting a wireless adapter for your laptop stop reading and just buy a USB dongle you can’t add PCI devices to a laptop.
If your wanting to add wireless to a desktop though that is a different story. PCI devices are much faster than USB devices, and can achieve much greater speeds, and allow for more stable connections. Their raw power, and ability to transfer data is much higher than a USB dongle.
While I say PCI don’t worry if all you have are PCI-E slots most if not all WiFi adapters have this port option available.
Usually these kind of adapters are best if you do a lot of bandwidth intensive task, and game a lot. Their price is not bad either considering they range from $10~$100 dollars. The more you pay the better off you are though. At $10 your probably looking at B/G wireless adapters which will max out at 54mbps which for more people is good enough, and perfectly fine for gaming or YouTube. If you need more though be ready to pay more.
Doing a quick Amazon search you can see the prices aren’t bad. PCI devices are really easy to install too. All you got to do is open the side of your computer see which slot it fits, and than identify that slot if it exist on your motherboard. These days they are usually marked on the board as well in white text. You can also look online using Google image search.
USB WiFi Adapter (Dongle)
Depending on who you go with, and what speeds your looking for these range from just a few bucks to $40+ according to Amazon. The main thing with USB Wifi Adapters is that they are convenient, pretty fast, and very portable. If your laptop’s WiFi adapter burns out a cheap USB Wifi Adapter is the best option rather than getting it repaired.
USB Adapters are great for space too. Usually people who are working on small projects with Raspberry Pi devices use these to give their devices WiFi capability.
The downside to USB WiFi adapters are signal range, and the fact they usually max out at 300mbps on the market. Anything above 300mbps starts to get expensive.
If your looking for convenience, or need a laptop WiFi replacement than get a USB WiFi adapter. If your using a desktop than I would recommend a PCI or PCI-E WiFi adapter card which are relativity cheap, and easy to install.
