So my pc is upstairs and my service provider is Rogers. I just bought a 100ft cat 6 ethernet cable to connect it from my router to my pc directly. I pay for 1000 down but im only getting a max of 60. When i use my powerline adapter i get 50. I'm not really sure why the speed is so low because when my pc was downstairs i used to get much much faster speeds. Could it be the length? Is the wire defective?
