Speed limited to 100 megabits per second
You're experiencing inconsistent speeds depending on your PC. It seems the issue might be related to driver settings or network configuration rather than the cable itself. Try checking drivers, adjusting network adapter properties, or testing with a different device to narrow down the problem.
Your PC might only have a 100MB network card. Could you share your system details? It’s tough to fix without any information.
Verify the physical connector, ensuring pins aren't touching each other—this can occur occasionally during plugging or unplugging. For a 2.5 Gbps Ethernet card, confirm you have the most recent driver installed. Open Device Manager, navigate to your network card settings, and turn off any power-saving options (such as green Ethernet or eco mode). This forces your network card to operate at full power, potentially improving signal strength. In rare instances, using a lower-quality cable (especially long ones with poor CCA) can cause excessive signal loss if the card operates at reduced power levels. If enabled, it may mistakenly downgrade to 100 Mbps instead of transmitting at the intended speed.
I own a Ryzen 5 5600x paired with a B550M Aorus Elite. It confirms compatibility with 1gbps.
The cable functions properly. It worked on another machine and displayed 1gbps, but on my PC it only reached 100mbps.
Inspect the inside of your Ethernet port thoroughly, confirming all eight pins are properly aligned and not overlapping. Verify if you receive 1 Gbps using another cable. You can establish a link between two computers via a short cable for testing purposes—directly connecting network cards will ensure functionality.
All eight connections line up perfectly. I achieved 1gbps using a different Ethernet cable. With another setup, I managed to reach 1gbps, but not with this Cat6 flat cable—only on another device could it perform that way.
