Learn why a router is an important piece of computer hardware and what you need to know to maintain and troubleshoot it.
A router is an important piece of hardware that allows devices to connect to the internet. It allows you to access websites, play games, send emails, download documents, stream videos, and do anything else that requires an internet connection. It forwards packets of information from your internet provider to different devices to get connected, such as computers, laptops, and smartphones.
Depending on your needs or the needs of your clients, you can use two main types of routers: wireless routers and wired routers.
A wireless router allows you to connect to the internet with an antenna. These antennas are built into wireless routers and devices to communicate back and forth via internet connection. The router gets its internet connection through an Ethernet cable connected to a modem, a device your internet service provider places in your space to get internet.
You can operate an electronic device with WiFi capabilities from anywhere in your proximity without being limited to a physical location next to the router.
A wired router requires you to physically connect your device to the router using an Ethernet cable plugged into each device for a wired connection. Your router is also connected to your modem through an Ethernet cable.
A wired router allows you to have the same connection to the Internet but does not allow you to move to different areas and stay connected. However, wired configurations tend to provide greater security and connection speed.

Router configurations
A router is a key device for connecting your home electronics to the internet. It receives internet data from your modem and forwards it to your devices (computers, phones, tablets) wirelessly or via cables. Wired connections offer better security and speed, while wireless routers provide more flexibility in device placement.
