Restarting your eero or your network couldn't be simpler, and you can do it from your app with a couple of clicks.
1. Open your eero app
2. Identify the eero that's been designated as your 'Gateway' device (in this case it's called Living Room') and press it. (Always start with the gateway eero, but you can restart other leaf/node eero's by selecting them rather than the gateway device)
3. Press the Settings icon (that's the circle with the tree little dots at the top right)
4. Scroll down and press 'Restart <Device Name>' (In this case it's Restart Living Room)
5. To continue, press Restart eero at the bottom of the screen
