Network cable for long-range connections
Network cable for long-range connections
today i set up a long network cable in my new room. first I used a 25-meter one, then added an extender with ethernet ports on both sides, followed by another 10-meter cable, all using cat 6. currently it delivers 130/40 mbps, while the service plan is 250/100. when testing with my laptop and a 1-meter cable from the router, I got 230/80, which works fine for me. i’m wondering if the signal quality drops significantly at around 35 meters (about 35 yards). it seems unusual that the loss is so high. what should i do?
According to the electrical spec, it performs up to 100 meters. Below that range you should have no problems, and above it it typically won't function properly or may trigger many errors. You can connect the extender shown here: https://smile.amazon.com/Inline-Coupler-...B07DWPW5MJ
It suggests the 130/40 outcome came from another device, not just your laptop. The laptop might have been used with a different cable.
I would strongly exclude that particular coupler. Usually they aren't that problematic, but there seems to be an issue with the line. My approach would be: 1. Run each cable through the same PC and check if speeds match closely—no more than a few percent difference. You shouldn’t notice a big gap like before. 2. Then test the coupler using fresh cables and compare the results. In an ideal scenario, you could use Cat6 over 100 meters (~320 feet). If removing the coupler is feasible, I’d do that.
