- Click Connect. It's in the lower-right side of the network's name box.
- Enter the network's password. Type in the network's password when prompted.
- Click Next. It's below the network. As long as the password is correct, doing so will connect you to the network.
- Connect other computers in the network to the Internet. For each computer that you want to use in your network, repeat the Wi-Fi connection process. Once each computer is connected to the Wi-Fi network, you can proceed with setting up file sharing.
- Open Start
- Type in control panel. Doing so will search your computer for the Control Panel app.
- Click Control Panel. It's a blue rectangle icon at the top of the Start menu.
- Click Network and Sharing Center. This option resembles a set of blue monitors.
- If you see "Category" in the upper-right side of the page, first click the Network and Internet heading on the main Control Panel page.
- Click Change advanced sharing settings. It's a link in the upper-left side of the page.
- Check the "Turn on network discovery" box. This will ensure that your computer can interact with other computers that are plugged into the Internet source.
- You can also enable the "Turn on file and printer sharing" option and the "Allow Windows to manage homegroup connections" option if they aren't automatically selected.
- Click Save changes. It's at the bottom of the page.
- Enable network discovery on the other network computers. Once each computer in the networked group has network discovery enabled in Control Panel, your wired network will be ready to use.

- Close the System Preferences window. Your changes will be saved; the current computer is now set up for network sharing.
- Enable file sharing on the other network computers. Each computer that's connected to your Internet source will need file sharing to be enabled. Once you've completed this process, your wireless network will be ready to use.
Method 3 of 4:
Using a Wired Network on Windows
- Make sure that you have the necessary hardware. You'll need an Internet source (e.g., a router) into which you can plug each individual computer, as well as Ethernet cables to connect the computers to the Internet source.
- Most standard routers only come with a few Ethernet ports, but you can buy network hubs that support upward of 10 connections.
- Make sure that you know the approximate distance from each computer to the Internet source. You'll need Ethernet cables that can span this distance.
- Set up the Internet source. Plug one end of an Ethernet cable into the "Internet" port on the back of the modem, then connect the other end of the cable to the "Internet" or "Ethernet" port on your Internet source.
- You'll also need to plug in the Internet source's power cable before proceeding.
- Plug each computer into the Internet source. Attach one end of an Ethernet cable to the square Ethernet port on your computer, then attach the other end of the cable to the Internet source.
- Typically speaking, you'll use desktop computers for a network, which means the Ethernet ports will be on the back of each CPU box.
- Open Start
- Type in control panel. Doing so will search your computer for the Control Panel app.
- Click Control Panel. It's a blue rectangle icon at the top of the Start menu.
- Click Network and Sharing Center. This option resembles a set of blue monitors.
- If you see "Category" in the upper-right side of the page, first click the Network and Internet heading on the main Control Panel page.

- You can also enable the "Turn on file and printer sharing" option and the "Allow Windows to manage homegroup connections" option if they aren't automatically selected.
- Click Save changes. It's at the bottom of the page.
- Enable network discovery on the other network computers. Once each computer in the networked group has network discovery enabled in Control Panel, your wired network will be ready to use.

- Typically speaking, you'll use iMac computers for a network. This means that you'll find the Ethernet port on the back of the iMac's monitor.
- If you're using Mac laptops for your network, you'll need to buy a USB-C network adapter for your computer and then plug it into one of the USB-C slots on the side of your Mac, since Mac laptops no longer include Ethernet ports.
- Open the Apple menu
- Click System Preferences…. It's near the top of the drop-down menu.
