Hi all,
I’ve been wiring my house with cat6 cable and ran into an issue where I’m getting very poor speeds at the end of a run. I ran a cable from my fibre modem into the basement then back up and into a network switch behind my TV. I did a speedteat on my Xbox over wifi and received 150~mbps, I then plugged the cable into the Xbox from the switch and only received 50~mbps. I thought maybe the switch was lagging me down even though it’s rated for gigabit so I plugged the ethernet cable I ran directly into the Xbox and it dropped to 35~mbps. The cable length is far less than what it’s rated for, less than 100ft for sure. I have no idea what the issue could be but open to any ideas.
Thanks
Edit: wanted to add, I wired them as T-568B and used a cable tester which ran 1-8 successfully.
Bad punches at the end of your runs is one possibility. Cheap/bad cable is another.
Another - maybe more likely - explanation is that the cable runs parallel to some electrical wire and induction is generating RFI on your CAT6 cable.
