Introduction

Most of us are aware, that network security is extremely important. If your WiFi network is not properly secured, it makes you and all of your home or office resources vulnerable to a variety of security threats. To stay ahead of the curve, many companies and home users have guest WiFi. Unlike your regular WiFi network that you or your company members use, the guest WiFi network restricts what your guests can do in your network. It gives visitors access to the Internet connection, but nothing else making you or your company a lot more secure. This chapter is a guide on configuring a guest WiFi.
