All-In-One Modem/Router (often referred to as a Gateways and are offered by most ISP's) is a combination Modem/Router. 

With Winston's new support for All-In-One equipment the installation is much simpler, as the configuration would be the following:

Combination modem/router LAN -> Winston WAN (with no connections needed to the LAN port of Winston).

Note: Disabling IPv6 within the router is required for this new installation method for proper connection to the Winston Dashboard.

If you do encounter any errors during the setup of Winston with this new installation method please proceed with a power reset of Winston and refreshing the setup page.
