A step-by-step guide to setting up a UniFi network

1. Access Phase

  • Assess your network requirements: Determine the size of your network, the number of devices you'll need (access points, switches, routers, etc.), and any specific features or configurations required.
  • Map out the network layout: Identify the physical locations where devices will be installed and plan the network topology accordingly.
  • Consider power and cabling requirements: Ensure that you have sufficient power sources and Ethernet cabling infrastructure to support the devices' placement.

2. Hardware Setup

Start by connecting the UniFi devices (access points, switches, etc.) to power and network (Ethernet) connections. Make sure they are properly powered up and ready for adoption.

3. UniFi Controller Installation

  • If you aren't using a DreamMachine or Cloudkey download and install the UniFi Controller software on a computer or server. You can choose to install it on-premises or use a cloud-hosted instance.
  • Launch the UniFi Controller and follow the initial setup wizard to configure the basics, including language selection, time zone, and administrator account setup.

4. Device Adoption

  • Access the UniFi Controller interface and log in using your administrator credentials.
  • Go to the "Devices" section and click on "Adopt" to start the device adoption process.
  • The UniFi Controller will search for devices on the network. Once discovered, you can adopt them and assign them to specific sites or network groups within the controller.

5. Network Configuration

  • Configure the network settings: Set up the network SSID(s), security protocols, VLANs, guest access, and other relevant network configurations in the UniFi Controller.
  • Set up device-specific configurations: Customise settings for each device, such as transmit power, channel selection, and specific features unique to the device model.

6. Monitoring and Management

  • Monitor device status and performance: Use the UniFi Controller to monitor network device status, client connectivity, network traffic, and other key metrics. Leverage the analytics and reporting features to gain insights into the network's performance.

Troubleshooting

Device Adoption Issues

Issue: Difficulty adopting UniFi devices in the UniFi Controller.​
Solution: Ensure that the devices are on the same network segment as the UniFi Controller. Verify that the UniFi Controller software is running and accessible. If adoption fails, try resetting the device and adopting it again. Make sure to update the device firmware and UniFi Controller software to the latest versions.

Wireless Coverage and Connectivity Problems

Issue: Weak signal or dead zones in certain areas of the network.
Solution: Optimise access point placement to ensure adequate coverage. Consider factors like interference, building materials, and the number of connected clients. Adjust transmit power, channel selection, and channel width settings to minimise interference and maximise performance. Use additional access points strategically to extend coverage and provide seamless roaming.

Slow Network Performance

Issue: Slow network speeds or high latency.
Solution: Verify that the network hardware (routers, switches) can handle the desired bandwidth and traffic load. Optimize network settings, such as QoS configuration and bandwidth management, to prioritize critical applications and manage bandwidth allocation. Check for any network bottlenecks or sources of congestion and adjust accordingly.

VLAN and Routing Configuration

Issue: Difficulty setting up VLANs or routing between different network segments.​
Solution: Ensure that VLANs are properly configured on the UniFi devices and UniFi Controller. Verify that the proper VLAN tagging is applied to network ports and access points. Check firewall rules and routing configurations to allow traffic flow between VLANs. Double-check that the DHCP server is correctly assigned to the appropriate VLAN.

Guest Network Issues

Issue: Problems with guest network access or captive portal functionality.
Solution: Verify that the guest network settings are correctly configured in the UniFi Controller, including authentication methods and captive portal customization. Check that firewall rules are correctly set to allow guest network traffic. Clear browser cache and cookies if users experience issues with captive portal authentication.

Firmware and Software Updates

Issue: Delayed or unsuccessful firmware or software updates.
Solution: Ensure that the UniFi devices and UniFi Controller are on compatible firmware and software versions. Verify that the devices have proper internet connectivity to download updates. If updates fail, try restarting the devices and the UniFi Controller. Consider updating devices manually if automatic updates encounter issues.

User Access and Permissions

Issue: Difficulty managing user access and permissions within the UniFi Controller.
Solution: Verify that the administrator account has appropriate privileges to manage the network. Create additional user accounts with limited access if needed. Double-check the access rights for specific network configurations and features within the UniFi Controller to ensure proper permissions for different user roles.
