    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.

    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.

    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.

    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.

    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.

    • 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.

    Yes, in the server settings menu, you type SMB colon, forward slash, forward slash, followed by the name of the computer you're looking to connect. That should connect the PC.

    You may not have computer discovery or file sharing turned on. You need the computer to be "unlocked" for it to connect to a network.

  • Question
    How do I set up a computer with proper subnet masks for a local network?
    Community Answer
    Without knowing what IP addresses you are using I can only give you an estimate. I can show the default values based on the private IP addresses I assume you're using. If you see anything between 10.0.0.0 and 10.255.255.254, the default subnet mask is 255.0.0.0. If you see 172.16.0.0 to 172.31.255.254, the default subnet mask is 255.255.0.0. If you see 192.168.0.0 to 192.168.255.254, the default subnet mask is 255.255.255.0, which is the most common range on home equipment and small networks up to 254 computers, so I would guess this is the one you need.
