Objective
This article describes how to troubleshoot load balance failure on the Omada Gateway.
Requirements
Introduction
Load Balance is mainly used in multi-WAN scenarios, in which the Omada Gateway will distribute network traffic to multiple WAN ports based on traffic and resource usage, reducing network congestion and resource wastage.
If your network includes multiple Internet Service Providers (ISPs), you can use dual or multiple WAN ports to access the Internet. The Omada Gateway's Load Balance feature can distribute network traffic proportionally to the WAN ports. The device will then determine the WAN port for the next data packet based on the currently online WAN ports and the weights you set for each WAN link.
Troubleshooting Steps
Step 1. First, check the physical connection of the WAN ports to see whether the network cable is loose and whether the WAN LED of the gateway is blinking.
Step 2. Go to Status > System Status to check the connection status of the WAN ports. If Load Balancing is enabled, the ports should be displayed as Link Up.
Step 3. Go to Transmission > Load Balancing > Basic Settings to check whether Load Balancing has been enabled.
Step 4. Check the port status of the WAN ports.
Go to Transmission > Load Balancing > Online Detection to see whether the corresponding WAN ports are Online.
Note: If the WAN port is displayed as Offline, go to Transmission > Load Balancing > Link Backup to check whether the port is configured as Backup WAN. If not, check the ISP network connection of the WAN port.
Step 5. Refer to the configuration guide (Why cannot I get multi-wan bandwidth aggregation test effect via speedtest.net by SMB router?) and test the speed correctly with Load Balancing enabled.
Note that the unsatisfactory Speedtest® results should not be the sole criterion to judge whether Load Balancing is effective or not. When using Speedtest®, the server will build multiple sessions with the device that will distribute traffic according to the connected sessions. However, the number of sessions is limited for a Speedtest® server. Thus, some WAN ports may receive fewer sessions that do not fully utilize the bandwidth, leading to lower actual speed than expected.
Conclusion
This article briefly introduces the Load Balance feature and its troubleshooting steps. If the function still fails to take effect following these steps, contact TP-Link Support for technical assistance.
