bought 5m, and connected to my router Netgear R7000, in lieu of a Category 6 cable is gray and ugly. Unfortunately if the cable is flat, white and pretty it is not recognized by my router as a gigabit cable (diode lit in orange instead of white) so I removed. The test also makes my Freebox Revolution Live (by disconnecting the netgear router), and the same problem. Yet by taking a cable Category 7 I had thought it would be above the Category 6.
