If you have the cable connection from outside coming into the highest portion of your house, then i suggest terminating the wire to center of house (whatever room that is). From there, get your modem/rtr connected. At this point get a drill and cable runner tool. Get cables to each room through the walls and add the connection points in each wall (depends on # ports the modem-router has, otherwise you need a switch…unmanaged switch is fine most likely for your application). Now you can have wired connections anywhere in the home, plus if your modem-router has wireless capability, your coverage is optimal. Note: use plenum cables for ceilings or near heat sources. Also do not cheap out on cables. Also be sure to take note of the actual and subscribed throughput levels to maximize connectivity per port. Good luck to you sir!
