What is guest WiFi and how does it work?
Guest WiFi is a separate network that is created for visitors or guests to use when they are on your premises. This network is typically isolated from your main network, which means that guests cannot access your private files, devices, or sensitive information. When a guest connects to your guest WiFi, they are usually required to accept your terms of service and may be asked to provide some basic information, such as their name and email address. This information can be used to send them a welcome message, provide them with information about your business, or to follow up with them after their visit.
The guest WiFi network is usually created by configuring your router to broadcast a separate SSID (network name) that is specifically for guests. This network can be configured to have its own set of rules and restrictions, such as limiting the amount of bandwidth that guests can use or blocking access to certain websites. By creating a separate network for guests, you can provide them with a convenient and secure way to access the internet while protecting your main network from potential security threats. This is especially important for businesses, as it allows them to provide a useful service to their customers while minimizing the risk of a security breach.
