    If a direct connection from a laptop in the living room to the modem is getting slightly over 100 Mbps instead of 200 Mbps, that still sounds like something is flaky.

     

    What color is the link light on the R6400 LAN port connected to the living room?  It should be white for Gigabit speeds.  If it's amber then the port is running at 100 Mbps, so either your cable is faulty, the distance to the living is too far or there is interference affecting the line (e.g. A/C power lines may be too close).  

     

    Gigabit Ethernet requires all 4 wire pairs in the Cat 5e cable to be in good working order.  Do you have a cable tester (like this)?  While it can't detect interference, it can verify basic connectivity on all 4 wire pairs.
