  3. Basic Configuration

    • Create admin account
    • Set up site information
    • Configure basic network settings (DHCP, DNS, etc.)
    • Adopt devices into the network

Network Design Best Practices

  1. Wireless Network Planning

    • Conduct site survey for optimal AP placement
    • Configure appropriate channels and channel width
    • Set appropriate transmit power levels

  2. VLAN Strategy

    • Segment network for security and performance
    • Create separate networks for IoT, guest, and trusted devices
    • Implement appropriate firewall rules between networks

  3. Security Implementation

    • Enable IDS/IPS features
    • Configure WPA3 where possible
    • Implement 802.1X authentication for enterprise environments
    • Create guest portal for visitor access

Advanced Configuration

Performance Optimization

  • Fast Roaming

    • Enable 802.11r for seamless handoff between APs
    • Configure minimum RSSI thresholds
    • Optimize band steering settings

  • Quality of Service (QoS)

    • Prioritize critical traffic
    • Limit bandwidth for non-essential services
    • Create traffic shaping rules

Remote Access

  • UniFi Cloud Access

    • Enable remote management
    • Configure two-factor authentication
    • Set up notifications for important events

  • VPN Configuration

    • Set up L2TP, OpenVPN, or WireGuard
    • Configure split tunneling if needed
    • Implement proper access controls
