How to access Expert settings on Home Internet

Its not a router. Its Gateway. They are similar in ways. Routers have built in gateways. the gateway in your router is only used if computers on the local network are using different protocols. It makes those computers able to connect and talk on the intranet of the local network. Gateways do that over the internet, but do not handle port forwarding. That would put your local network at risk by exposing it externally. A router has also a network switch built in. A router should always be before the gateway. A router has a firewall that protects its switch from from unwanted incoming traffic. NEVER hook a switch or managed switch to a gateway. Gateway to router to switch then from the switch to access points or computers. The only exception to this would be if you wanted to have a hardware backed firewall other than using the routers firewall. you then would connect the firewall to the gateway first. 

 Hope this helps everyone understand, ISP's don't build your local intranet, they supply your local intranet the gateway to the internet.
