Problem streaming Amazon/ Netflix UHD
LG 65ub9200 TV with WIFI router getting greater that 35 mbs, (recommended 25 mbs or more) ; the picture for UHD on Amazon Prime and Netlix looks very bad and buffers. The tv is about forty feet away from router in an enclosed room with block wall. Would running ethernet cable directly to TV resolve the poor streaming. Its not the TV because BLU Ray looks amazing!
