Network problems at home Issue with connectivity or device performance
Hello there! I'm just getting started with Linus's YouTube channel and have been following it for a while now. I'm trying to get my home network set up properly. I have an ISP box from Plusnet inside the wall, which has an Ethernet port for connecting to my router and a power jack. My PC is on one side of a door, and I've been using some internal trunking to connect everything through a wall box with RJ45 ports. I'm planning to expand it later by running cables into other rooms.
Recently, I noticed my internet speed isn't what I expected. After setting up the initial connections, I did a speed test and found that my download speed was only around 90 Mbps, while upload was about 70 Mbps. When I tried a direct Cat6 cable from the ISP box straight to my router, the speed improved significantly—over 500 Mbps—but the upload stayed the same.
I'm puzzled by this drop in performance when using the port I connected it to. The patch cable is Cat7 and only about 20 feet long, while the ISP box uses a 30-foot Cat6 cable. It seems like the distance might be affecting the signal quality. Could anyone help me understand what's happening?
Since the connection speed is under 100 Mbps, the problem likely lies with the cabling. Only four wires are sufficient for 100 Mbps or less, but eight are required for speeds above that. Consider reterminating the cable. Ethernet works well within about 100 meters.
It looks like the problem persists even after testing with the patch cable. The tester initially showed all 8 pins connected, but now only one is disconnected. It seems the connection wasn’t fully broken at first, which might have been a lucky break. I’m considering switching to an unshielded Cat6 cable and using a male connector for the ISP box. The Cat6a cable was tricky to work with initially—maybe the wires or insulation are too thick or thin. Thanks for the advice!
