Question: Can Two Routers Be Used on the Same Home Network?
You or your family may be considering purchasing a new home network router to upgrade from an older one. Or perhaps you have a very large home network already and are wondering whether a second router can improve performance.
Answer: It is technically possible to utilize two routers on the same home network. The benefits of a two router network include:
  • supports more devices - if your first router is a wired Ethernet router, it supports only a limited number of connected devices (typically only four or five). A second router provides more open ports allowing additional computers to join the network.

  • can simply hybrid network setups - if you have a wired home network and want to connect some new Wi-Fi devices to it, installing a wireless router as the second router allows those devices to connect while allowing the rest of the network to remain on Ethernet.

  • wireless range / reach - adding a second wireless router to a Wi-Fi network can extend the reach of your network to accommodate far away devices.

  • network isolation - If you heavily utilize the network connection between certain computers (such as frequent large file transfers, or LAN gaming), installing those computers to use one router, isolates the network traffic from affecting the other router and all of its attached devices.

Installing a Two Router Network

Installing a router to work as the second one on a home network requires special configuration. Setup involves choosing a good location, ensuring the right physical connections, and configuring IP address settings (including DHCP).

Alternatives To a Second Router

Instead of adding a second wired router to an existing network, consider adding an Ethernet switch instead. 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 setup.
