Problem with Ethernet connection not resolved.
Problem with Ethernet connection not resolved.
Our ethernet ports in our bedrooms never worked since we moved in. Wifi is fine and we assumed it was a bad cable from the termination hub to the modem. So we ran a new cable through last night and punched down ourselves. We wired it according to the color codes and since our hub is a 568-A version, all the others looked fine too. But our ethernet still does not work. Any suggestions? Here is a link to what our hub looks like https://smile.amazon.com/Open-House-H628...Y0BGN3B6QS Here are pics of our cables as well. The blue ones were already plugged in when we got here and we did the whiteish/gray one.
Wiring appears intact at this location; do you have a switch available for connection? To activate Ethernet, you’ll need a network switch along with patch cables connecting the top ports of the termination hub to the switch/router/modem. The panel shown is only for routing cables—it lacks any communication electronics. For testing, connect an Ethernet cable from the modem’s LAN port into the RJ45 port above your new cable, then plug a laptop into the wall outlet on the opposite side and check if you can access the internet.
Today most cables use the T568-B format. A cable switching from T568-A to T568-B should function (at least 100Mbit) as long as your gear supports Auto-MDIX, which has been around for a while. A tester would be helpful—it can confirm whether a connection is being made.
I tried it myself. I connected the other side (with the RJ45 cap) to the tester. Used a fresh cable and plugged it into the other end of the tester as well as the port above the termination line. It seemed to be incorrect, here the video https://photos.app.goo.gl/Wg8HHc5RBXQSCg16A
It looks like there are several issues here. Each LED should turn green one after another, but some aren't working at all, indicating a lack of connection. Others are red, suggesting the cable was cut or damaged. This usually happens when using T568-A and T568-B on the same cable. Even though such cables might still function if the devices support Auto-MDIX, a hub isn't a switch and likely won't work properly now. That could explain why you're not getting internet. Some cables are straight-through, others are crossover, so compatibility matters.
These connections are really exposed, but you should ensure each wire has a light with the continuity tester. Many people find it normal to see nails or damaged wires affecting the map. If your device uses alligator clips, you could inspect each one separately. TIA568A/B isn’t too critical since gigabit standards support auto MDI/MDIX.
