If you have two networking devices in your home, they are usually a modem and separate standalone router.

When tracing wires from the wall jack, the coaxial cable first leads to your modem, which usually has a single ethernet port. The ethernet wire coming out of the modem connects to a router, which often has antennas and multiple ethernet ports.

The WAN port of Winston should be connected to your Modem and the LAN port should be connected to your router.

If you're unable to resolve the Winson Dashboard you will need to log into your router and set the primary DNS to with no secondary or tertiary DNS set.

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