However, what if you want to use a laptop or computer to access the Internet, from anywhere in your home? That's where a wireless router comes into play.

Introduction

A wireless router is basically a network device that lets you connect several computers to the Internet without the use of cables.
It works on the technology of wireless access points or WLAN. In essence, routers allow the freedom of several users to be able to access the Internet. Plus, they also free you from messy wires.

Working

This networking device works using signals that have the same radio frequency range as the wireless network card installed in the PC. The significant feature of this exchange of signal is that, both the devices function on the same radio frequency range, thus allowing the transmission of data to-and-fro between them.
Being an intelligent device, it can determine whether a signal needs to be transmitted to a local computer on the intranet or to the Internet.
The signal strength depends on the manufacturer of the device and the Internet Service Provider (ISP). A wireless network has the added functionality of providing security with firewalls, keys, filters, etc.

Setup

To set it up, all you need to do is connect it to your Internet connection and install the drivers in your system. When you purchase this device you get the following: a user manual, driver installation disc, instructions, and setup guide. Simply follow the instructions given in them.

Advantages

4. User-friendly: The installation and setup process is very easy.
