- 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.
