Private IP Address Use with ASUS AiMesh System Behind TP-Link ER605 Router
If you have a gigabit fiberONT TP-Link ER605 router and an ASUS AiMesh system, you might notice that the ASUS AiMesh system is assigned a private IP address, which is behind the TP-Link ER605 router. This article will explain the concept of private IP addresses, the reasons behind this setup, and how to configure your network for optimal performance.
Understanding Private IP Addresses
Private IP addresses are special IP address ranges that are not globally unique and are not routed on the Internet. These addresses are used for local communication within a private network. The three commonly used private IP address ranges are:
- 10.0.0.0 to 10.255.255.255
- 172.16.0.0 to 172.31.255.255
- 192.168.0.0 to 192.168.255.255
In your case, the ASUS AiMesh system is assigned a private IP address from the 192.168.x.x range, which is typical and poses no issues as long as your network is configured correctly.
Reasons for Private IP Address Assignment
The TP-Link ER605 router assigns private IP addresses to devices connected to its LAN ports or through Wi-Fi. This is done for the following reasons:
- Security: Private IP addresses are not accessible from the Internet, providing an additional layer of security.
- Address Conservation: Private IP addresses allow for a larger number of devices to be connected to a local network without running out of unique IP addresses.
- Simplicity: Using private IP addresses simplifies network configuration and management.
Configuring Your Network
To ensure optimal performance and proper communication between your devices, follow these steps:
- Connect your gigabit fiberONT to the WAN port of the TP-Link ER605 router.
- Connect the ASUS AiMesh system to one of the LAN ports of the TP-Link ER605 router.
- Log in to the TP-Link ER605 router's web interface and reserve a static IP address for the ASUS AiMesh system within the DHCP reservation settings.
- Ensure that the ASUS AiMesh system is configured in 'Router' mode instead of 'Access Point' mode.
- Verify that both the TP-Link ER605 router and the ASUS AiMesh system have the latest firmware installed.
