A wireless router is a device that connects to the internet and allows multiple devices, such as computers, smartphones, and tablets, to access the internet without physical cables. It uses radio waves to transmit data, enabling users to connect to the internet from various locations within a home or office. In addition to providing internet access, a wireless router often includes features like security settings to protect the network and the ability to manage connected devices. Many modern routers also support advanced technologies, such as Wi-Fi 6, which enhances speed and efficiency for users with multiple devices.
