You have two setup options:
I. Add Plume to your current setup
You can leave your current wired connection setup as is, keeping your existing router to connect your wired devices and handle routing functions. Plug in Plume to an open Ethernet port on your router or switch. Set the Plume network mode to 'Bridge Mode' will enable both networks to see each other and Plume handles the Wi-Fi from there. We recommend you turn off the Wi-Fi on your old router once Plume has been setup.
II. Connect the device or switch to a Plume Pod
Each Plume Pod comes with an Ethernet port. You can connect a device or switch to the Pod with an Ethernet cable. If your devices are located in the same room as the first Pod (connected to the modem), you can add another Pod to connect your wired devices. Please note you will need to power cycle the Pod for the device to be recognized on the network.
A. Modem -> Router -> Plume Pod
B. Modem/Router -> Plume Pod with additional Plume Pod for your wired device
C. Modem/Router -> Switch -> Plume Pod
