TL-SG105s reduces my speeds
I've just purchased the above Ethernet switch. Before fitting the 20 m Cat 7 cable I tested it with my PC upstairs (from router) and I got a speed of 560!! I then ran the cat 7 cable into the switch, which is upstairs then a cable to my PC from the switch I only get 230.
The switch has reduced the speed by 330, any explanation?
