Cat6 bandwidth restricted
Cat6 bandwidth restricted
Hi everyone, my Cat6 cable isn’t hitting the full 1000mbps speed—it’s capped around 100mbps. A tester confirmed all eight wires are functioning properly, with signals sent and received on every wire. The router’s back light now displays orange instead of green. TL;DR: I recently moved into a new home and started working from home. To improve privacy, I kept using an old Cat5e cable for my PC. It worked well with a 1GB fiber connection, but I needed a more stable solution. I ordered Cat6 shielded cable and tested it—signals appeared on all eight wires. I’m still unsure if it can reach 1GB over such a distance, so I’ll measure the remaining length and estimate maybe 40-50 meters before it drops.

). It seems I'll need to replace the Cat6 cable, though I hope there are other options. Removing the current and rerunning it would take a lot of time and money. T568B is what I'm using. I also tried A, but it didn't help much. Both ends match, which is good. My tester confirms this too—it sends a signal through each wire and shows the expected pattern. If a connector isn't properly crimped, it will show "receiving signal 1" and so on.

10-13-2024, 11:50 PM #4I don't have another machine or router on hand. I've put a switch in between, connecting the PC to the switch at 1000mbps. However, real speeds only reach 100mbps. I'm currently stripping the remaining Cat6 cable and planning to run it internally between rooms for testing. Unfortunately, I can't move the PC around (WFH—need it online ).

Connecting router to switch to Cat6 cable and then to PC creates a path for data transfer. You're concerned the signal might be dropping during this process. If STP was used, both ends should be properly grounded. Otherwise, the setup might not function correctly, especially at higher speeds like 10Gbps or 1Gbps. Issues often appear around 10Gbps, making your setup special. We've encountered problems with 100Mbit/1Gbit settings before, but people usually check for hardware issues first. Right now, I'm trying various devices to figure out what's wrong.

10-13-2024, 11:50 PM #7I don't believe anything is properly grounded. I just remove the shielding and attach the connector. It's not near power lines either. I bought shielded because I thought it was a smart move, felt safer at the time.

10-13-2024, 11:50 PM #8STP functions best when both connections are correctly grounded using shielded RJ-45 connectors. Your goal is Gigabit, but without power lines nearby it shouldn’t affect performance. Share your progress on the workaround you’re using. The wire tester might not be precise enough for a damaged wire that could hinder data transfer.
I plan to download everything later and troubleshoot again with a direct connection. I'm using shielded cables—should I just confirm the shield from the cable connects to the metal shielding on the connector?

10-13-2024, 11:50 PM #9I just tried using the Switch after the router. Router > Switch > cable to PC. No signal came through. I thought about replacing the connector, but it seems the Switch might be the issue or the new one is working. I checked the old one carefully and it was fine, but now it functions.

10-13-2024, 11:50 PM #10Tested without the switch, everything functions now. It was only the connector. I’ll just have to hide in embarrassment later. Anyway, I’m sure the updated connectors will be adopted eventually.
