Some homes (typically in apartment buildings or where there is a fiber optic internet service line) only have a router indoors because the line coming into the wall jack is already modulated/demodulated. 

If you are unsure whether your networking device is just a router or a combination modem/router, a quick online search of the make/model of your device can help clarify, or simply contact your Internet Service Provider.

See the below image for proper Winston setup with a Fiber connection (and only a router).

Please Note: 

- AT&T Fiber and Google Fiber both use their devices to authenticate the network, so they are treated as combination modem/routers and will need to be placed before Winston. Installing Winston

- Having an active VPN connection will result in the inability to access the Winston Dashboard.
