How to configure the router at the switch access point

To set up a router or switch as an access point, you need to configure its IP address, disable DHCP, and connect it via LAN to the main router while setting the wireless SSID and password.Understanding AP Mode vs Router ModeRouter Mode: The device manages network traffic, DHCP, NAT, and firewall functions.Access Point (AP) Mode: The device acts solely as a wireless access point, extending the existing network without handling routing functions. In AP mode, DHCP and NAT are typically disabled, and the device relies on the main router for IP assignment and network management .Steps to Configure a Router as an Access PointReset the Secondary Router: Press the reset button for 10 seconds to restore factory settings and note the default IP and login credentials .Connect to the Main Network: Use an Ethernet cable to connect a LAN port on the secondary router to a LAN port on the main router . Avoid using the WAN port unless specified.Log into the Router Interface: Open a web browser and enter the router's IP address (found on the device label or via a network scan) to access the web management page .Set a Static IP Address: Assign an IP address in the same subnet as the main router but outside its DHCP range (e.g., if the main router is 192.168.1.1 with DHCP 192.168.1.100–192.168.1.200, set the AP to 192.168.1.2), .Disable DHCP: Turn off the DHCP server on the secondary router to prevent IP conflicts .Configure Wireless Settings: Set the SSID (network name) and password for the AP. You can match the main router's SSID for seamless roaming or use a different name for identification .Switch to AP Mode (if available): Some routers have an Operation Mode menu to select AP mode directly, simplifying setup .Reboot and Test: Save settings, reboot the router, and connect a device to verify wireless connectivity and proper IP assignment from the main router .Additional TipsCable Length: Ensure Ethernet cables do not exceed 100 meters to maintain signal quality .Device Discovery: If the AP's IP changes after enabling AP mode, use the manufacturer's device discovery utility to locate it .Older Routers: If AP mode is not supported, manual configuration of IP, DHCP, and wireless settings is required .Switch Integration: If using a switch, connect it to the main router and then connect the AP to the switch; no additional configuration is needed on the switch itself. By following these steps, your secondary router or switch will function as an access point, extending your network coverage while maintaining centralized IP management and avoiding conflicts.
