Common Setup Challenges and How to Address Them

While the installation and configuration of the USG PRO 4 are generally smooth, there are some common challenges users may encounter. Here’s how to address them:

1. Device Not Showing Up in UniFi Controller:

• Problem: If the USG PRO 4 does not appear in the UniFi Controller after being powered on.
• Solution: Ensure the USG PRO 4 is connected to the same network as your UniFi Controller. You may also need to reset the device (by holding the reset button for about 10 seconds) and attempt the adoption process again. Ensure your UniFi Controller software is up-to-date.

2. WAN Connectivity Issues:

• Problem: If the device is not able to connect to the internet through the WAN port.
• Solution: Double-check the WAN port configuration in the UniFi Controller. If your ISP uses dynamic IP (DHCP), make sure the settings are configured correctly. For static IP or PPPoE connections, input the required details such as IP address, subnet mask, and gateway.

3. Slow Network Speeds with DPI Enabled:

• Problem: Enabling Deep Packet Inspection (DPI) can slow down network speeds, especially during heavy traffic periods.
• Solution: If you’re experiencing slow speeds with DPI enabled, try adjusting the DPI settings to reduce the amount of traffic analyzed or disable it temporarily. The USG PRO 4 can still maintain a high level of security with DPI off, though enabling it provides extra protection.

4. VPN Setup Errors:

• Problem: Users may experience difficulties when configuring the VPN.
• Solution: Ensure the VPN settings (IPsec, L2TP) are configured correctly. Verify that firewall rules allow VPN traffic on the appropriate ports (e.g., 500/UDP for IPsec). Also, ensure remote users have the correct credentials and network settings to connect.

5. Firmware Issues:

• Problem: Some features may not work as expected due to outdated firmware.
• Solution: Always ensure your device firmware is up-to-date. The UniFi Controller provides automatic firmware update prompts, or you can manually check for updates in the settings section.
