![]() But instead of terminals, it’s using IP addresses. It performs “traffic directing” on your network, sort of like a traffic director on an airplane runway directs planes to the appropriate terminals. How it WorksĪ router forwards data packets between computer networks. Without a modem, however, neither of us can get online. For example, I can send a file to my co-worker’s computer through the LAN. You don’t actually need a router to connect to the Internet, but you do need one if there’s more than one device on your network, or if you’re using Wi-Fi.Ĭonversely, if you have only a router and no modem, the devices on your LAN can still communicate. The router allows multiple computers to connect to the same modem, which provides access to the Internet beyond. If you’re not sure which box is your modem and which one is your router, routers usually have antennae for Wi-Fi. ![]() It’s the bridge between your computer and your modem. What Does a Router Do?Ī router has both a LAN port and a WAN port. Together, you have the basic setup to connect your small office or family home to the Internet. ![]() Through your modem, your LAN connects with the wide area network (WAN), which extends over a large geographical distance, such as Manhattan or any metropolitan area. Your modem faces outwards-it’s what connects your LAN to the outside world, the Internet. It creates a local area network (LAN), which is what you would call your internal network of computers in your office or home. Your router faces inwards-it connects multiple computers in one network together. They sit next to each other, they look pretty identical, and they both help you connect to the internet.ĭespite having so much in common, they are actually opposites. For suitable Ethernet switch and gigabit switch of good quality, FS would be your great choice.The router and the modem are two of the easiest devices to get confused. After two minutes, the network and Internet connection is ready to go.Īs you read this, you may be clear about the knowledge of Ethernet switch, router and modem and the proper way to connect them in a network. Step5: Plug the power supplies of the modem, Ethernet switch and router in. Step4: Connect another Ethernet cable to numbered Ethernet port on the switch and plug the other end into the LAN port on the wireless router. Step3: Plug the other end of Ethernet cable connected with modem into WAN port of router. Step2: Connect telephone wire with modem, and then connect an Ethernet cable to the Ethernet port on the back of the cable modem. Unplug any Ethernet cables that are plugged into any of them. Step 1: Unplug the power supplies of cable modem, switch and wireless router. Here are the detailed steps for connection: Placing the router between modem and Ethernet switch creates an extra layer of protection from threats on the Internet. Once the switch is behind a router (which in most cases uses NAT), all devices connected to either the switch or the router can access the internet simultaneously. There are a handful of ways to set up a shareable home network connection, but the safest and most reliable way is to use a router and switch in combination. Connection Between Ethernet Switch, Router and Modem The main purpose of a modem, when used in a home networking environment, is to establish a connection between your home network and ISP. A modem is a short way of saying “modulator, demodulator”, which is a hardware device that allows a computer to send and receive data over a telephone line or a cable or satellite connection.
