Hello - I use a Verizon Actiontech MI424WR router/modem which is directly connected to my iMac. I have an Apple Airport Extreme router and Airport Express extreme extender also installed.
My wifi download speeds are excellent for most of the house. However, they are terrible in the main TV room. I use MoCA connected to my TiVo for cable TV viewing so that is fine. However, my Roku is currently configured for wifi and that performance is poor.
I'd like to be able to use the Roku via Ethernet. Can I split the cable line and use some kind of ethernet converter for the Roku? Or can I add a second modem to the system that is closer to the TV? FiOS line-in from the street is accessible from the basement below the room I'm talking about. But I have no way of connecting to the Actiontech from that room.
