ℹ️ What is a Guest Network?

A guest network is a separate WiFi network that provides internet access to visitors while keeping your main network and connected devices secure. It's like having two separate WiFi networks from one router.

Network Architecture

Internet ←→ Router ←→ Main Network (Your devices)
↓
Guest Network (Visitors)

Guests get internet but can't access your main network
