Hello, after shutting down your PC, the 1.0Gbps connection is no longer active, leaving only 100Mbps available. I’m not sure if there’s a specific solution, but I can help troubleshoot further.
As Lurick suggested, examine the cable closely. Consider these steps: unplug the cable and plug it back in, restart your computer, verify the driver, and ensure the manufacturer’s driver is installed. Disable and re-enable the interface in Windows. If these don’t resolve the issue, inspect your switch, check the duplex setting, restart it, and test with a different known good cable.
