eero is designed to replace your current router with a WiFi system that provides greater Internet connection and reliability throughout your home. Most customers no longer need their older routers after installing eero.
Some customers prefer to maintain their existing routers alongside their eero networks. While this isn’t our preferred configuration, it is certainly possible and may even be necessary in certain networks.
When using eeros alongside other routers, we recommend putting either your existing router or your eeros into bridge mode. Doing so will ensure you maintain a single SSID for your network and minimize unnecessary interference. In this configuration, your eeros will still utilize mesh technology to help you increase the range and speed of your network. If you choose to bridge your eeros, however, please keep in mind that your existing router will manage your network traffic and your eeros will simply act as access points in the network. As a result, you’ll lose control over the advanced networking features available through the eero app. This is why we recommend that you bridge your existing router—as opposed to your eeros—whenever possible.
