How Do You Connect a Desktop Computer to Wi-Fi?
Most desktop computers come with a built-in Ethernet port for connecting to your local network and the internet via an Ethernet cable, but not all with Wi-Fi connectivity pre-installed. You can use a Wi-Fi adapter, of course, but you can also connect a desktop to Wi-Fi without an adapter. The easiest way to do it is using your smartphone’s built-in USB Tethering. Your PC should have connected to your local Wi-Fi network via your smartphone. You can confirm its active network connection by selecting the Taskbar Icon arrow in the bottom right of your screen, then select the network icon. It will appear as a rectangular screen—not a Wi-Fi symbol, as the computer is technically connected to Wi-Fi over a wire). Select the Network you’re connected to (in our screenshot, Network 5) to go to the Network and Sharing Center. There you’ll see your newly connected network as being Connected. If it says No Internet, confirm that your smartphone is on the Wi-Fi network. If it is, but you still don’t have internet, follow router troubleshooting steps to get yourself back online.

When ready, follow these steps on how to share your internet connection.
Can a PC Connect to Wi-Fi Without Ethernet?
Ethernet is a wired connection, so if you want to connect to a wireless Wi-Fi network, you don’t need Ethernet at all. The best way to connect to your Wi-Fi network is by using a Wi-Fi adapter. Some desktop PCs and most laptops have them built-in, but there are add-in ones you can buy. They are relatively affordable and offer the best speeds without being limited by battery life. Alternatively, you can use a smartphone and USB tether it as in the instructions above, but you’ll need the correct USB cable, and you won’t be able to unplug your smartphone if you want to retain that Wi-Fi connection on your PC.
How Can you Connect a Desktop PC Without Internal WLAN to a Wireless Network?

The only downside is that you must leave your smartphone plugged in to take advantage of it.
