What device allows you to set up your home WiFi connections?

The device that allows you to set up your home WiFi connections is a router. A router serves as the central hub that links your various devices, such as computers, smartphones, and tablets, to the internet. It manages both the data traffic between these devices and the connection to your internet service provider via a modem.

When you have a broadband internet connection, the modem connects to the internet, but it is the router that enables you to create a local area network (LAN) and provides WiFi access throughout your home. It does this by broadcasting a wireless signal that devices can connect to, allowing them to communicate with each other and access the internet without the need for physical cables.

In addition, a router often comes with built-in firewall functionality to enhance your network's security, but its primary role regarding WiFi connections is to facilitate and manage the wireless networking aspect.
