Setting Up a Guest WiFi Network Safely

Most modern business-grade routers and access points support a separate guest WiFi network, and setting one up is worth the ten minutes it takes. It gives visitors, clients, and contractors internet access without putting them on the same network as your servers, printers, and business data.

When configuring a guest network, make sure "client isolation" or "AP isolation" is enabled if available — this stops guest devices from even seeing each other, let alone reaching your internal systems. Use a separate password from your main network, and change it periodically.

If your guest WiFi traffic is heavy (for example, a retail or hospitality location), consider whether it needs its own bandwidth allocation so guest usage can't slow down the connection your staff depends on for business systems.
