What does a wireless router do?

A wireless router primarily functions by distributing a signal wirelessly, allowing multiple devices to connect to the internet and communicate with each other without the need for physical cables. This capability is fundamental to creating a wireless local area network (WLAN), which enhances convenience and mobility for users.

In addition to its core role of connecting devices, a wireless router typically incorporates features such as internet security and the ability to manage network traffic. However, its main purpose is focused on the wireless distribution of signal, which enables smartphones, laptops, tablets, and other devices to access the internet seamlessly. This wireless connectivity is essential in modern households and workplaces, where mobility and ease of access are prioritized.
