Devices: Secondary Router (TP-Link AX1500/TP-Link AX1800) - Unreachable Primary Router
In a typical home network setup, two routers are often used to extend the network coverage and provide a stable connection to multiple devices. This article focuses on the scenario where the secondary router, either TP-Link AX1500 or TP-Link AX1800, is unable to reach the primary router.
Understanding the Setup
The two routers in question are TP-Link AX1500 and TP-Link AX1800. The primary router is connected to the modem via its WAN interface, while the secondary router's WAN interface is connected to one of the LAN ports of the primary router. This creates a network topology where all devices connected to either router can communicate with each other.
Troubleshooting Unreachable Primary Router
When the secondary router is unable to reach the primary router, it could be due to several reasons. Here are some steps to troubleshoot the issue:
- Check the physical connections: Ensure that the Ethernet cable connecting the secondary router's WAN port to the primary router's LAN port is securely connected.
- Restart the routers: Sometimes, a simple restart can resolve the issue. Restart both the primary and secondary routers and check if the secondary router can now reach the primary router.
- Check the IP address settings: Ensure that the secondary router's IP address is within the IP address range of the primary router's DHCP server. If the IP address is outside the range or if it is static, it might not be able to communicate with the primary router.
- Update the firmware: Ensure that both the primary and secondary routers are running the latest firmware. Outdated firmware can cause compatibility issues and prevent the secondary router from reaching the primary router.
- Check for interference: Other networking devices or electronics can cause interference and prevent the secondary router from reaching the primary router. Move the secondary router away from such devices and check if the issue is resolved.
Configuring the Secondary Router
If the secondary router is still unable to reach the primary router after troubleshooting, it might be necessary to manually configure the secondary router. Here are the steps to do so:
- Connect the secondary router to a computer using an Ethernet cable.
- Access the secondary router's web interface by entering its IP address in a web browser.
- Change the secondary router's IP address to an available IP address within the primary router's DHCP range.
- Disable the secondary router's DHCP server to avoid IP address conflicts.
- Save the settings and reboot the secondary router.

After following these steps, the secondary router should be able to reach the primary router. If the issue persists, it might be necessary to contact TP-Link support for further assistance.
In conclusion, having two routers in a home network can provide better coverage and stability. However, it is important to ensure that both routers can communicate with each other. By following the troubleshooting steps and configuring the secondary router correctly, the network should function smoothly.
