I have a D-Link DIR-615 router and there is an Ethernet port in my room that is connected to one of the router's LAN ports. But it's stowed away in a closet so Wi-Fi signal is abysmal at some areas of the house. I have a spare SMC router and I would like to use it as a way to expand Wi-Fi range by connecting it to the Ethernet port. No, I'm not talking about amplifying the pre-existing Wi-Fi signal but to add another network so I can be completely wireless in my room. Still stuck with Ethernet. Is there an easy way?
