You have two setup options:
I. Add Plume to your current setup
You can leave your current wired connection setup as is and plug in Plume to an open Ethernet port. Plume handles the WiFi from there, and we recommend you turn off the WiFi on your old router.
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.
A. Modem -> Router -> Plume Pod
B. Modem/Router -> Plume Pod with additional Plume Pod for your wired device
C. Modem/Router -> Switch -> Plume Pod
