I recommend everyone by PING test ping his router. Of course, with Gb link. So for me a lot of packet loss were also extremely general and Ping was 20-30% lower than with a standard CAT6 cable. Just because 1Gbit network status are, that does not mean that such a connection also runs perfectly. Had I but also wondered if such a flat cable could offer the same performance. Perhaps in a few meters, but at 15m it is definitely in the trousers.
