You can replace your router with Plume or add Plume to your existing network setup.
Plume Replaces Your Router
You’ll still need the modem as always, but can ditch the router! From now on, your modem will connect directly to Plume. Whichever Pod you connect to the modem will automatically become the Gateway Pod that directs all others, so no need to be picky. Keep in mind that any hardwired devices will need to be connected to another Plume Pod in this scenario.
Here's a diagram of your old setup:
Remove the old router and replace it with a Plume Pod.
Add Plume to Existing Setup
If you need to keep your router to access some of its features, you can setup Plume by connecting a Pod to the router. Just remember to turn Wi-Fi off on your router after the setup. Your networking mode is set to Auto by default to allow Plume to select the appropriate networking mode for you.
