 Commercial Wi-Fi Deployment Guide: Router + Access Point

1. Understanding the Setup

Component Role
Router Connects to ISP, handles DHCP, NAT, firewall, and overall routing.
Access Point (AP) Extends Wi-Fi coverage — acts as a wireless bridge to the router.

 2. Connecting Router to Access Point

 Option A: Wired Access Point (Best for Commercial Use)

  • Connect Ethernet from router LAN port to AP's uplink port.

  • Set AP mode: Switch to "Access Point Mode" (check the vendor UI).

  • Turn off DHCP on the AP to avoid conflicting IP assignment.

  • Assign Static IP to AP (e.g., 192.168.1.2) in the same subnet as the router.

🔄 Example:
Device IP Address DHCP
Router 192.168.1.1 ON
AP 192.168.1.2 OFF

💡 Tip: Use PoE (Power over Ethernet) if available, to power APs without extra adapters.

 

2. Configuring Wi-Fi for New Customers

✅ Public Guest Network (Hotels, Cafes, Malls)

  • Create a Guest SSID on the AP.

  • Isolate guests from private/internal LAN (via VLAN or AP settings).

  • Enable a Captive Portal:

    • Show welcome/login screen.

    • Collect email or accept terms.

    • Optional: payment or voucher system.

  • Rate Limit users (e.g., 5 Mbps down/1 Mbps up).

  • Session timeout (e.g., auto-disconnect after 2 hours).

Optional Add-ons:

  • Social login (Facebook, Google)

  • Splash page branding (for marketing)

 Security Considerations

  • Use WPA2/WPA3 for private SSID.

  • Disable WPS and change default credentials.

  • Regular firmware updates.

  • Use firewalls or VLANs to prevent unauthorized LAN access.
