Why set up a guest Wi-Fi network?
The most compelling reason for setting up a guest Wi-Fi network is security. Your main network handles all your data, including any shared network storage, passwords, and personal information. It’s best practice to keep too many people from having access to that. Guest networks also keep your main network safe if a visitor accidentally connects a malware-infected device.
Another reason to set up a guest network is to have more control over your guest’s internet use in your home. Many guest network settings allow you to limit the number of devices connected to the network or how much bandwidth the network can use.
Both these reasons make guest Wi-Fi networks great for small businesses, homes with visitors, and homes with renters. It keeps your networks safe, and it prevents others from running over your data cap and costing you a fortune in overage fees.
