Their is only one phone jack where a modem can be placed in our house and it is to complicated to get Ethernet from the modem up to my computer. I can still connect with wireless internet but I want to be able to use Ethernet. The modem is a all in one (router+modem). If I buy a router and place it in my room can it connect to the all in one modem without using a phone jack (Just plugging it into the power outlet) alowing me to connect the router to the PC using Ethernet?
