I previously had cat5 from my router in the garage run through my house to my room. I then have that go into a gigabit switch, which goes to the computers throughout the room. Now that I have put in CAT6 into the room, I have been having problems, including one being that the connection was actually bottle-necked to 100mbps(when I checked via ethernet card status). I fixed this by just using a normal cat5 cable to the switch to my computer. Now the problem I face is that from the same location as my computer, my phone gets a faster speed on wifi than the ethernet itself. I have no idea why this would happen since cat6 should be considered a faster cable, right? If I wanted to fix this, would I just want to rerun from the wall port to the switch with cat5e cables?

Thanks

EDIT: I also have recently got a new router, which is the ASUS RT-AC5300 along with the cable change in my room. If this may have effected it, please feel free to let me know:)

One problem is that if you don't have all four cable pairs correctly connected, your 1000BASE-T (1 Gbps) connection will drop to 100BASE-TX (100 Mbps).

Another problem is that even experienced cable installers have trouble getting Category-6 or above to pass all the tests in the Category Test Suite.

Unless you have a real (read expensive) cable tester, you will not be able to certify a Category-6 cable. I don't mean any disrespect, but I seriously doubt that you could install a Category-6 cable and get it to pass the test suite.

The cat6 cable you have is either damaged or badly terminated.

Cat6 cable is not necessarily faster, it is designed to work better with higher frequencies and noise cancellation - but has tighter requirements for how it can be run (bend radius, termination etc).

Both Cat5e and Cat6 can carry gigabit traffic (cat6e will do better on 10gig connections)

  • I have Cat5e run from my router through the walls and into my room. Would the mismatch between Cat5e and Cat6 possibly slow it down? – Wup123 Apr 7 '17 at 19:21
  • No, you can use cat6 patch cables on a cat5e cable or vise-versa. Of-course, cable joins add reflections and worse depending on how they are done. The key thing is to work out why your connection has negotiated at 100 megabit - this would probably not be a cable issue, unless wires are not broken. – davidgo Apr 7 '17 at 20:19
