3. Will it work with Modem +
Router (
also known as DSL Router)?
Very few modem + routers can turn a LAN port into a WAN port.
In case you want such a device, please look around on the forum for model numbers (
Asus DSL-
AC68U,
TP-Link TD-W8968). In most cases, Modem + Router will not work out for you.
