How to Extend Wi‑Fi Coverage: Add a Second Router in Three Simple Steps

This guide explains three practical methods for expanding home Wi‑Fi coverage by adding a second router—using a secondary router as a WAN‑linked device, converting it into a switch, or configuring it as an access point—complete with step‑by‑step configuration details and screenshots.

How to Extend Wi‑Fi Coverage: Add a Second Router in Three Simple Steps

Method 1: Secondary Router as a WAN‑linked Device

When a house is large or a villa, a single router often cannot cover the whole area, so a second router is added.

Connect Router 1 to Router 2 – Use an Ethernet cable to connect any LAN port of the primary router (Router 1) to the WAN port of the secondary router (Router 2).

Set Router 2 WAN IP – In Router 2’s admin page go to Internet Settings → WAN Settings → WAN Connection Type and select Auto‑obtain IP address (or DHCP). Save the changes.

Configure Router 2 LAN IP – Change the LAN IP to a different subnet (e.g., 192.168.2.1) so it does not conflict with Router 1’s 192.168.1.1. Disable the DHCP server on Router 2. Save and reboot.

Method 2: Use the Secondary Router as a Switch

Turn the second router into a simple switch by disabling its DHCP server and assigning it a LAN IP in the same subnet as Router 1.

Change LAN IP – Set Router 2’s LAN IP to 192.168.1.X (2 < X < 254) while keeping the first three octets identical to Router 1.

Disable DHCP – In the router’s admin page go to DHCP Server → DHCP Service and turn it off.

Method 3: LAN‑to‑LAN Connection (Router 2 as Access Point)

Connect a LAN port of Router 1 to a LAN port of Router 2 using an Ethernet cable (do not use the WAN port). Ensure Router 2’s LAN IP is in the same subnet as Router 1 and DHCP is disabled. After these steps, Router 2 will provide Wi‑Fi coverage without creating a separate network.

All three methods configure only the secondary router; the primary router does not need any changes, but it must be functioning correctly before extending the network.
