How to Add Wi-Fi to your Desktop PC

I was looking for a spare PC, and I found one in my storeroom. When I turned it on its working fine, but I couldn’t connect it to Wi-Fi. In the past, I usually connect to the internet through an Ethernet cable on my PC. Now, everyone uses wireless devices and don’t need Ethernet cables anymore.
