LAN connection issues at gigabit speed Device not responding Network configuration problems
Your setup shows clear differences in performance based on location, suggesting hardware factors rather than just software settings. The cables and router capabilities don’t match the speeds you’re seeing. Consider checking the physical connections, cable quality, and possibly testing with a different device. If issues persist, contact your ISP for further diagnostics.
Indicates a broken cable because Gigabit needs all four pairs (eight wires) properly connected and functioning to operate at that rate. A single damaged wire usually causes a drop to 100Mbit in most scenarios.
If the low speeds match using the port on the second floor, it likely points to a faulty cable.
I believe they're referring to the cable in the wall. It's worth checking if everything connects through the same ports and seeing if any are damaged or if the sockets in different rooms have issues. I'm also testing as many devices as possible directly on the router to confirm the problem isn't with those machines. Regarding your speed test, the variability you're seeing might be due to servers not supporting your connection speed. Gigabit connections can be challenging because many speed tests only offer 10Gbps servers.
I ran the Ookla and QuickLine speed tests. The fiber optic cable connects to a box on the first floor, then four cables go into the walls to reach four spots on two floors. I attempted to swap the cables from the box to check for damage, but it didn’t work. The cables on the first floor provide gigabit speeds, while the second floor does not. It might be that the installer accidentally damaged them during the routing process upstairs.
If the cables aren't checked, you'll never be sure they'll function correctly until you attempt your current task. With a warranty on the work, you can contact the company to report the issue and request repairs. You might choose to handle it yourself, but you'll need a LAN cable tester, a crimping tool, RJ45 connectors, and patience to properly re-crimp the Ethernet connections. Always verify that the standard procedure matches at both ends when working independently.
