Can Two Routers Be Used on the Same Home Network?
Yes, using two (or even more than two) routers on the same home network is possible. The benefits of a two-router network include:
Support for more wired devices: If the first router is wired Ethernet, it supports a limited number of connected devices (typically only four or five). A second router provides more open Ethernet ports, allowing additional computers to join the network. Support for mixed wired and wireless network setups: If you have a wired home network and want to connect Wi-Fi devices to it, installing a wireless router as the second router allows those devices to communicate while allowing the rest of the network to remain on Ethernet. Conversely, a second router also helps when most clients in the home are wireless, but a few Ethernet devices in one room (like game consoles and file-sharing servers) could benefit from a wired setup. Improved wireless reach (signal range): Adding a second wireless router to an existing Wi-Fi network can extend its reach to accommodate far away devices. Network isolation: If you heavily utilize the network connection between specific computers (such as frequent large file transfers or LAN gaming), installing those computers to run from one router keeps that network traffic from affecting the other router and its attached devices.

How to Use Two Routers in One House
Installing a router to work as the second on a home network requires a special configuration. Setup involves choosing a good location, ensuring the right physical connections, and configuring IP address settings (including DHCP).
Alternatives to a Second Home Router
Instead of adding a second wired router to an existing network, add an Ethernet switch. A switch accomplishes the same goal of extending the size of a network, but it does not require any IP address or DHCP configuration, greatly simplifying the setup.
